The present invention discloses the stereo projecting method and apparatus of non-stereo cine film, and features that two frames of image with the basically same contents and backgrounds but with difference in taking time and space are used as one pair of images with certain spatial visual different for the right and left eye of the viewer to simulate the parallax between two eyes. The cinema projector is so improved that the dislocated superposed image on the screen consists of two frames meeting the stereo parallax of two eyes. The viewer wearing the polarizing glasses can separate the right and left images automatically and the images on the retinan of two eyes have always time and space difference to activate the latent stereo visual function of visual system in viewer's brain and to produce stereo feeling of viewing image separated from the screen.
Description
The invention belongs to the motion picture projection technique field; The three-dimensional projection method and apparatus that relates to non-three-dimensional film particularly relates to two images with time difference that utilize conventional plane screen film movie, annular screen film movie, concave ball shape screen film movie and arrives the three-dimensional projection method and apparatus of space-time function conversion.
At present the film movie projector adopts electric motor driven sprocket that film is pulled through the sheet window with single-image hole off and on the standard speed of per second 24 frames.This single-image is put the visual effect stagnation that image method causes the projection of plane film movie in decades, and at present the film of plane film because of take or manufacturing technology improve and maturation and large-scale application make the content kind of film of made still with suitable quantity growth, along with having increasing plane film, the prosperity of film industry comes out, no matter how high the scientific and technological advanced degree of the shooting of film and the equipment that post-production is adopted is, no matter its manufacturing cost is high to what degree, how the effect of computer three-dimensional making that let it be yet is tending towards true, projection screen becomes the barrier that separate of spectators between the photoplay plot all the time, the reality of the on all four imaging on the retina of both eyes of the spectators left and right sides can only mainly be realized its stereoeffect by the association or the understanding of spectators' brain to plot.
The stereoscopic visual effect of people's eyes in the true stereo environment mainly is to carry out vision logic comparison and generation by the translation of general image and dislocation and difference overlapping, local pixel.Twentieth century, the film equipment engineering technical personnel succeed in developing the stereo colour film, and spectators can enjoy is rich in relief art of film, makes spectators feel on the spot in person; The stereoscopic rendering of stereopsis by spectators with special eyeglasses separate a left side automatically, the image of right eye association, become the standard of whole world maturation, but the shooting of three-dimensional film TV is to adopt the two-shipper simulation, or exaggeration people's eyes are taken synchronously, increased the difficulty of taking, though the shooting of part stereopsis at present adopts the unit after improving to take, these facility have the anthropomorphic dummy eyes 65mm spacing about take the object that window is taken close shot, but the stereopsis development still is in initial stage, the manufacturing cost of stereopsis is still quite expensive, and its shooting and post-production technical difficulty are more much bigger than plane film.
The method and apparatus that the purpose of this invention is to provide a kind of three-dimensional projection of non-stereo film film, by improvement to existing non-stereo film movie projector, increase corresponding parts, make mute in plane or the screen of curved surface metal to be imaged as the content major part identical, basic corresponding pixel has certain difference, orthogonal basic corresponding two images of right and left eyes of stereoeffect when taking of polarization direction, spectators separate the dislocation image of right and left eyes correspondence automatically with going up the special-purpose left and right sides orthogonal polaroid glasses of light transmission shaft direction, left eye or right eye are watched the certain shooting time difference of corresponding existence or certain shooting spatial diversity piece image respectively, through the image pixel contraposition of the left and right sides of spectators' brain vision system, mathematical logic computing and fusion, make spectators feel to put the shadow dynamic image and separate, provide more real three-dimensional perfect the enjoyment to spectators with screen.
The objective of the invention is by to the physiological structure of people's eyes and the analysis of function, to people's the cerebral cortex vision system left and right sides binocular stereoscopic visual sense formation and the analysis of production process, and the analysis of each process of people's binocular stereo vision and corresponding several models again in conjunction with the shooting of various non-stereo film films and projection equipment to the shooting of each each picture of camera lens and the analysis of projection process, and by existing projection equipment being improved accordingly or reequiping, the stereopsis function of the vision system of each eyes when having the picture of regular hour difference and spatial diversity that the special-purpose polaroid glasses that increase corresponding parts or device and cooperate spectators to put on activate that spectators left and right sides eyes watch the film movie projection realizes the three-dimensional projection of non-three-dimensional film.
The retina photosensory cell is nearly more than 100,000,000 in each human eyeball, each photosensory cell surface diameter is about 2-6 μ m, they are distributed on the eyeball inwall concave ball shape retina, set up people's eyeball perfect optics regulating system model respectively, retina cell's induction model in the eyeball to the visible light of different colours varying strength, the desirable mathematical distribution model of retina cell's set in the eyeball, the electrophysiology information addressing conduction model of visual response cell mass, the contraposition pixel mathematics logical operation synthetic model of regional vision about the cerebral cortex visual centre, the brain visual centre cooperates other sensory synchronous perception information and produces the model of final electric physiological vision stereoscopic image in the past with reference to vision historical trace information and learning experience.With various ideal models the binocular stereo vision process is described below, the perfect optics regulating system comprises folding, may command light-inletting quantity iris, the imaging crystal of eyelid and regulates muscle accordingly and refreshing smart conduction path, follow adjusting muscle and the refreshing smart conduction path that zone motion up and down and left and right sides eyes focus on about the binocular vision maincenter by the suitable rotation of regulating left and right sides eyeball, and their common coordinative role makes on people's the retina of both eyes and clearly manifests the extraneous scenery optical imaging that human brain is thought perception; On the shape of intraocular retina photosensory cell and function, can be divided into cone photosensory cell and body of rod photosensory cell, because of respectively having superiority to the power of light and color reaction, they determine their quantity and the difference of distribution, is that benchmark numbers in order with each photosensory cell with the photosensory cell position on the eyeball visual axis, the interior retina photosensory cell of left eye ball has L1...LN, and (N=1.07 hundred million, variant specific to everyone), the retina photosensory cell has R1...RN in the right eye ball, each retina photosensory cell all has corresponding god to be proficient in the road to link to each other with the visual centre of brain, the retina photosensory cell is divided into two parts of flexibility and changeability in the left eye ball by the zone, a part is variable haplopia district, a part is variable diplopia field, the retina photosensory cell also is divided into two parts of flexibility and changeability in the right eye ball by the zone, a part is variable haplopia district, a part is variable diplopia field, retina photosensory cell diplopia area size is along with the angle of binocular visual axis changes and respective change in the eyeball of the left and right sides, the interior retina photosensory cell haplopia area size of ball this moment changes and correspondingly does with the diplopia area size variation of complementation along with the angle of binocular visual axis, left eye is about 150 degree of angular field of view in the horizontal direction, right eye is about 150 degree of angular field of view in the horizontal direction, right and left eyes is at about 140 degree of vertical direction angular field of view, and horizontal direction angular field of view about 180 is spent after the angular field of view logical OR computing of right and left eyes, about 140 degree of vertical apparent direction angular region; Behind the angular field of view logic and operation of right and left eyes square to angular field of view about 120 the degree, at about 140 degree of vertical direction angular field of view, focus on the corresponding change of angle of the variation adjusting optical axis of three-dimensional scenery distance along with eyes, behind the angular field of view logic and operation of right and left eyes in the horizontal direction the visual angle size to faint variation should be arranged, the size of the retina photosensory cell diplopia field of right and left eyes is corresponding simultaneously changes synchronously, though the imaging content in the retina photosensory cell diplopia zone of right and left eyes is identical, but the viewpoint of its observation is at a distance of about 65 millimeters and make the local detail of imaging that certain difference be arranged, retina of left eye photosensory cell diplopia field domain imaging is the take back image of face of observing scene, retina of right eye photosensory cell diplopia field domain imaging is the take over image of face of observing scene, and the degree of their each local overlapping dislocation focuses on the corresponding synchronous change of variation of three-dimensional scenery distance simultaneously along with eyes.When eyes are watched scenery outside 500 meters, binocular visual axis is substantially parallel, arbitrary air coordinates is put the straight line at pupil of left eye center and the angle Φ L between the left eye optical axis and this point to the straight line at pupil of right eye center and the angle Φ R basically identical between the right eye optical axis on 500 meters outer scenery, make the imaging content in 500 meters outer scenery retina photosensory cell diplopia zone of retina photosensory cell set in the right and left eyes eyeball identical, the size of its dislocation and retina photosensory cell sizableness though local detail has small dislocation, the electrophysiology information addressing conduction model of visual response cell mass that causes each retina photosensory cell diplopia zone of right and left eyes adopts symmetrical contraposition addressing mode to learn the diplopia zone corresponding image signals that the logical operation synthetic model transmits few of difference to the left and right sides of cerebral cortex visual zone visual image prime number, learn haplopia region image signal that the logical operation synthetic model transmits with the simple independent addressing conduction of electrophysiology information of the visual response cell mass in each retina photosensory cell haplopia zone of right and left eyes to cerebral cortex visual zone left and right sides visual image prime number and be merged into scene image outside in the eyes angular field of view 500 meters, thisly lack the relief image of partial 3 d (in brain, producing) near two-dimensional characteristics and cooperate other sensory perception information again and produce the final record in short-term of visual pattern and handle with reference to vision historical trace information and learning experience in the past (with the bioelectricity form in brain) with the bioelectricity form, also can produce certain stereo perception to some scenery by the comprehensive comparison of integral body or local message, but this stereo perception varies with each individual and results from the final stage of binocular vision process, this stereo perception degree brachytely degree is slow, needs the participation consciously of people's brain.When eyes are watched the scenery at 10 meters, the binocular visual axis ∮ that forms an angle, arbitrary air coordinates point D on 10 meters the scenery
X, Y, zArrive the straight line at pupil of right eye center and the angle ∮ R between the right eye optical axis because of D to the straight line at pupil of left eye center and the angle ∮ L between the left eye optical axis and this
X, Y, zX, Y, each parameter change of Z and marked change, though the imaging content in the scenery at 10 meters retina photosensory cell diplopia zone of retina cell's set in the right and left eyes eyeball is identical, to the arbitrary air coordinates point D of the scenery at 10 meters
X, Y, zThe arbitrary air coordinates point D of respective differences similarities and differences scenery of the coordinate position of the imaging in the retina photosensory cell diplopia zone of retina photosensory cell set in the right and left eyes eyeball
X, Y, zWith eyes cooperate angle parameter ∮ L, ∮ R has direct relation, there were significant differences to make the coordinate of 10 meters the scenery corresponding pixel of the imaging in the retina photosensory cell diplopia zone of retina photosensory cell set in the right and left eyes eyeball, the electrophysiology information addressing conduction model contraposition indexed addressing regional visual image prime number to about the cerebral cortex visual centre of visual response cell mass that causes each retina photosensory cell diplopia zone of right and left eyes is learned the logical operation synthetic model and is transmitted the diplopia zone index contraposition picture signal with local coordinate difference, cerebral cortex visual zone left and right sides visual image prime number is learned the logical operation synthetic model and is received after these diplopia index contraposition information every pair of pixel according to it on a left side, the numbering of the imaging on the retina of right eye or respective coordinates are carried out fast and fuzzy mathematics trigonometric function operation, greatly blur scanning calculating about the tens million of electricity physiological signals to each retina photosensory cell diplopia zone of right and left eyes within 15 milliseconds to the paired pixel on the retina photosensory cell, in brain, draw the electric physiology stereoscopic three-dimensional image of scenery visual angle, 10 meters diplopia field, learn the scenery combined electrical physiology stereoscopic image that haplopia range image signal that the logical operation synthetic model transmits is merged into 10 meters in the eyes angular field of view with the simple independent addressing conduction of electrophysiology information of the visual response cell mass in each retina photosensory cell haplopia zone of right and left eyes to the left and right sides, cerebral cortex visual centre zone visual image prime number, the formation time of scenery combination stereogram elephant in this eyes angular field of view is approximately 16 milliseconds (receiving the picture information that 60 frames change by the multipotency of human visual system's per second calculates) the soonest, scenery combination stereogram picture in this eyes angular field of view produces with the bioelectricity form in brain fast and in real time and cooperates other sensory synchronous perception information, with reference to vision historical trace information and learning experience in the past the visual electrophysiology picture information that produces is done last record in short-term and processing again, scenery combination stereogram in this eyes angular field of view resembled in brain exist with the bioelectricity form, IC and the real corresponding 3D vision Virtual Space of three-dimensional world of behaving, biological information record space for the magnanimity that utilization ratio is the highest in the human brain, approximately through disappearing after 40 milliseconds short time, carry out about 40 milliseconds short time memory (retentivity time of eye that promptly it has often been said), can produce stereo perception by the comprehensive comparison of integral body or local message to the local image in the haplopia district of the scenery combination stereogram elephant in the eyes angular field of view, this stereo perception is people's a vision natural reaction.
When people's eyes are watched plane film and TV, plane dynamic picture imaging in the double eyeball of the normal person left and right sides on the retina is identical, three-dimensional scenery beyond the stereoeffect that it is faint and normal person's eyes are watched 500 meters is similar, have only by time concrete dynamic image, various contrast perception in the spatial dimension, and spectators in the past in the reference of the accumulation of real world neutral body vision and produce faint stereoeffect, this faint stereoeffect is different because of people's emotion, because of the scope of one's knowledge of people different, because of people's practice accumulation different, because of specifically the dynamic image content is different.
Human is through the evolution survival of the fittest of the biology in tens million of years and come as five-star animal, it also is state-of-the-art that the integrated performance index of its vision system is compared with rudimentary animal vision system, along with initially being born of people, the indefatigable work of people's vision system almost is accompanied by all activities except that sleep of people, human use's binocular vision systematic learning, practice, memory, enjoy life and live, IC electric physiology the people is simulated in the 3 D visual image forming process in the objective reality world, often is accompanied by people's emotion and the senior intelligency activity of brain.The physiology hardware change and the software function of human vision system, each stage in life the people changes to some extent, the physiology hardware of vision system forms in the g and D process of fetus, the perfect all one's life that is accompanied by him of the software function of normal person's vision system.The vision system of normotrophic fetus is shaped gradually along with the growth of the growth of embryonated egg, fetus, and is constantly perfect at its physiology hardware system of this stage, just do not pass through any practice of vision in parent.In the process that the vision system of fetus forms, also be accompanied by the growth of vision system software, these are grown functions and are determined by the information that inhereditary material is passed in the gene-code of fetus.Fetus becomes ewborn infant during the parent childbirth, its vision and various sensory system are adjusted with the shortest time as early as possible because of the unexpected variation of environment and are adapted to, show initial several days vision system and auditory system and faint, to such an extent as to before its eyes to ordinary person be normal various vision and acoustic stimulation test have no basically the reaction.This moment, the corresponding accumulation in its cerebral cortex sensory storage zone was blank out basically, and particularly the corresponding consciousness of eyes visual sense feel or knowledge accumulation are zero substantially.Distance between neonate's eyes is less, and the concrete distance between its left and right sides eyes is mind, and its size is different because of the size of neonatal brain or head; Earn out eyes in a few days, from noting the world on every side, the accumulation that has summing-up slowly note down and vision process in some emotion incident also be stored among neonate's brain, along with progressively rotating, eyes reach flexible, make him with less left and right sides eyes distance and inherent stereopsis, automatically calculate the real 3D world, adapting to the in riotous profusion three-dimensional world of color, along with his growing and the typing of brain structure size, eyes are maxd apart from becoming, to blue or green, middle age back eyes are stabilized in about 65mm (between the men and women and slightly variant between each individuality) as last apart from maxd.Eyes after finalizing the design to adult one apart from mind through the eyes of the natus of associating are apart from maxd, his stereo visual system all adapted to the most visual environment of life and preserved corresponding custom in the three-dimensional contraposition computation schema of vision, when three-dimensional film is taken with the sighting distance of mind between maxd, in corresponding projection process, corresponding adult can adapt to immediately; When a certain anaglyph is taken with the left and right sides window of 65mm sighting distance, the young child's incompatibility of fraction, because this part child's right and left eyes stereopsis system adaptive faculty is poor slightly, and the stereopsis of not accepting the 65mm sighting distance is taken exercise.And the distance of three-dimensional film left and right sides camera lens simulation that early stage first generation two-shipper is taken or exaggeration people's eyes, because of the distance of left and right sides two-shipper camera lens mostly greater than 65mm, captured three-dimensional film is when projection, some people incompatibility occurs and produces dizzy phenomenon, the software for calculation shortage that the appearance people cerebral cortex left and right sides binocular stereoscopic of dizzy phenomenon is looked corresponding the three-dimensional index of pixel, station-keeping mode causes, have only through the physiological progressively exercise of looking of human body and accumulate experience and be accustomed to, could enrich the kind and the experience of human brain stereopsis software identification.
When the cinematographer is in V
oThe platform that steadily moves of speed on; eyes are looked squarely left side or right side; that is to say that the line between travel direction and photographer's the eyes is substantially parallel; two movement locus is the same substantially about photographer; differ 65mm just before and after two the locus, in other words about two mistimings through certain point of locus be 65mm/V
o, work as V
oDuring=1.56 meter per seconds, two time differences through space point position are about 41.6ms about photographer, when direction of motion is benchmark with photographer for from left to right with V
oDuring=1.56 meter per seconds, it is basic identical that scenery that right eye is seen and left eye are seen after 41.6ms constantly; Dynamic image on the retina in the eyes of the photographer left and right sides is basic identical, just has the time difference of 41.6ms.As photographer according to the film pick-up machine with the standard shooting speed of per second 24 frames/s with V
oWhen taking on the platform of=1.56m/s speed motion continuously with the vertical substantially scenery of direction of motion, because of the time difference between the two adjacent width of cloth shooting picture is 41.6ms, the locus of the shooting between adjacent in other words two width of cloth pictures difference is 65mm, has just comprised the right and left eyes 3 D stereo dynamic image data that can reduce fully in the continuous single-lens picture of this section.When the three-dimensional projection of this section cinefilm, left eye and right eye are watched two adjacent pictures that have the 65mm spatial diversity when successively taking on the film respectively, give spectators with stereo perception.It is relevant with multiple factor in the following table that contiguous picture has the size of certain binocular stereoscopic picture information parallax on this film.

In most of the cases, movement velocity by the requirement video camera shooting platform of concrete condition is not at the uniform velocity, the sheet speed of walking of the normal photographic film of film generally all is to set for 24 width of cloth/seconds by the fixed speed in when projection, scenery motion conditions and relative parameter when taking according to adjacent continuous pictures, can calculate the differences in spatial location data message of the shooting point between adjacent two width of cloth pictures, if with this numerical information record with the camera site difference that can calculate on the perforation limit of film picture or be recorded in the perforation limit of film picture together with digital form with the data layout of special use with digital audio signal.Can be used as the basis of the lifelike three-dimensional image reduction projection when cinefilm is shown.
As non-three-dimensional film stereopsis projection method of the present invention, spectators are in each fragment of watching non-stereo film film or each moment, on the retina of both eyes of the left and right sides each imaging constantly all has certain difference, activate spectators' binocular stereo vision and produce stereoscopic vision, the position of arranging on the film is close to, content and background are roughly the same, just when taking, exist on the certain hour and the space on two width of cloth images of difference as a pair of right and left eyes image of the spatial vision difference of spectators' left and right sides eyes, make the dynamic image content on spectators' right and left eyes retina exist the interval of a frame or multiframe to misplace in time, make spectators produce stereo perception.Below by the projection of one section film stereopsis projection method of the present invention is adapted to the stereopsis of spectators' eyes and to be described further.
The a certain camera lens of non-three-dimensional film is by picture I, I+1, I+2, I+3, I+4 ... arrange by set form; Had within the projection time section at first 1/24 second two width of cloth adjacent pictures by camera lens simultaneously and by corresponding light path overlapping imaging in screen.In first 1/24 second time period, just in picture I, I+1 projection time section, left eye is watched picture I, right eye is watched picture I+1, picture I with the projection imaging of horizontal polarization light direction in the metal screen, spectators only make its only imaging in the left eye ball by the polaroid before the left eye, picture I+1 simultaneously with the overlapping projection imaging of vertical polarization direction in the metal screen, the polaroid of spectators before by right eye makes its only imaging in the right eye ball; Picture I and picture I+1 background when taking is roughly the same, and there is certain difference in content because of taking the time difference and concrete condition, and makes spectators' eyes produce stereopsis.In next 1/24 second time period, just in picture I+1, I+2 projection time section, left eye is watched picture I+1, and right eye is watched picture I+2, picture I+1 and picture I+2 background when taking is roughly the same, and there is certain difference in its content because of taking the time difference and concrete condition; The 3rd 1/24 second time period, left eye is watched picture I+2, and right eye is watched picture I+3, and each difference degree constantly of right and left eyes image is described with easy and fixing rule so like this.So circulation is up to the last piece image of each camera lens, and in the junction of two camera lenses, the shooting background of two images of adjacent this has very big difference in reaching.But this two widely different the persist times of image on retina have only 40ms, can not cause VC to spectators, though that is to say that the moment imaging on the intraocular retina in spectators' the left and right sides is different fully, but cause uncomfortable possibility minimum for spectators' eyes brain stereopsis, and this inadaptability is soon by adaptability replacement for a long time.
As non-three-dimensional film three-dimensional projection device of the present invention, can realize three-dimensional projection by improvement to existing non-stereo film movie projector, the film gate window of the projector after the improvement changes two identical windows into, make it corresponding with adjacent two width of cloth picture dimensions on the film, or film gate is made into long shape, two windows on the film gate corresponding respectively two contiguous width of cloth pictures on the film, the film traction mechanism of projector makes the picture on the film pursue the width of cloth by two picture windows on the projection film gate, projection light sees through on the film of sheet door and window and penetrates continuously, make two contiguous width of cloth pictures through projection lens and suitable light chopper and polarisation modulation, the horizontal displacement overlapping imaging is in the metal screen, spectators put on polaroid glasses, automatically separate two width of cloth images, make in spectators' the left and right sides double eyeball being imaged on each and all having difference on regular hour and the space constantly on the retina, activate the potential stereopsis function of spectators' brain vision system, the image that spectators are seen separates with screen, produces stereo perception.The film of taking below by the image pickup method of the stereopsis of several routines further specifies three-dimensional projection device of the present invention in three-dimensional projection device three-dimensional projection effect Analysis of the present invention.
When film pick-up machine during with the people of fixing seat in the plane taking moving or object, though background is identical on picture adjacent on the film of taking, but moving people and thing make the imaging difference to some extent on the adjacent picture in the photographed scene, there are positive parallax in the people who moves on some adjacent picture and the part of thing, and there are negative parallax in the people and the thing part of moving in some adjacent topography.When this section cinefilm image is shown by the solid reduction of the three-dimensional projection device of the invention described above, make the dislocation of right and left eyes image level, its depth of field of illusion that so identical static background is looked because of the reason and the binocular stereoscopic of positive parallax will be reduced, the information of local motion personage's relative positive negative parallax makes spectators feel on the spot in person equally.
When the seat in the plane of film pick-up machine to fix, with the video camera center left rotation and right rotation around the film of taking when the three-dimensional projection device projection of the present invention, there are negative parallax and the parallax free information zone of some part between the adjacent picture in the people of the motion in camera lens and thing, and most background all shows the effect of relative positive parallax when three-dimensional projection.

3The observed stereoeffect in position, the different size of this binocular parallax is relevant with the movement velocity of video camera, when movement velocity was very fast, the binocular parallax between the adjacent image was different bigger; When movement velocity was slow, the binocular parallax between the adjacent image was different less.
Improvement as three-dimensional projection method and apparatus of the present invention, in order to make spectators strengthen stereoeffect when the three-dimensional projection of watching above-mentioned non-three-dimensional film, the relative direction of motion of the moving situation of identification reference object or object during with the video camera photographic images, in the printing process of cinefilm, the right and left eyes discriminating digit signal when the corresponding film perforation marginal position between two adjacent width of cloth images adds the respective picture shooting; If the video camera photographed turns clockwise, then the viewed image of left eye is in time prior to the viewed image of right eye; On the contrary, if be rotated counterclockwise during the video camera photographed, then the viewed image of right eye must be in time prior to the viewed image of left eye, only in this way could guarantee that the stereoscopic image seen of spectators by the projection of cinefilm three-dimensional projection device is consistent with the truth of actual scenery.Because video camera may be clockwise shooting when foundation said method photographic images, also may be counterclockwise shooting, in corresponding three-dimensional projection device, the polarisation modulation when two adjacent width of cloth pictures are shown simultaneously should have respective flexibility.
Film projection send sheet speed because of the reason of visual flicker in the speed that was not less than for 24 width of cloth/seconds, that is to say that the sheet minimum speed of sending of film was 24 width of cloth/seconds when taking generally speaking, the stereopsis of translational speed when 1.56 meter per seconds are following for shooting platform reproduces, adjacent picture photographing space viewpoint spacing is less than 65 millimeters, and parallax is diminished.
Improvement as three-dimensional projection method and apparatus of the present invention, for the time lapse of the translational speed of shooting platform less than 1.56 meter per seconds, for increasing the spatial diversity degree of right and left eyes image, strengthen stereoeffect, with the adjacent N (N=1 that differs on this section film ... 10) two of individual picture picture conversion become the picture of difference of the visual space of left and right sides eyes.This section cinefilm is by picture M, M+1, M+2, M+3, M+4 ... arrange by set form; Each picture presentation has two close pictures by camera lens within the time period, overlapping imaging is in screen.When the shooting translational speed of shooting platform is 0.39 meter per second, have only when the N=4 by computing machine, promptly the parallax of any two pictures is 65 millimeters between 4 pictures, in first image time section, just in picture M, M+4 projection time section, picture M with the projection imaging of a certain direction of polarized light in the metal screen, spectators only make its only imaging in the left eye ball by the polaroid before the left eye, picture M+4 simultaneously with the overlapping projection imaging of vertical polarization direction in the metal screen, the polaroid of spectators before by right eye makes its only imaging in the right eye ball; Picture M and picture M+4 background when taking is roughly the same, and there is 65 millimeters difference in content because of taking the time difference and concrete condition, and makes spectators' eyes produce stereopsis.And then film indexing transfer mechanism alternation one width of cloth picture, make next picture presentation in the time period, picture M+1 with the projection imaging of a certain direction of polarized light in the metal screen, spectators only make its only imaging in the left eye ball by the polaroid before the left eye, picture M+5 simultaneously with the overlapping projection imaging of vertical polarization direction in the metal screen, the polaroid of spectators before by right eye makes its only imaging in the right eye ball.
Further improvement as the non-three-dimensional film projection method of the present invention, make two width of cloth pictures that transform to the space by the time be more suitable for spectators' right and left eyes stereopsis picture, give spectators more suitably visual enjoyment, must be in each width of cloth picture energy immediate addressing when showing of non-three-dimensional film, according to the information that is recorded in the right and left eyes image in the computing machine in advance, or directly be recorded in right and left eyes locating information on the film, by special-purpose positioning code signal at cinefilm perforation edge, or at the other information bar coded signal of printing special use of the perforation of cinefilm.Each cinefilm all is made up of to millions of pictures hundreds thousand of, and each picture is numbered the location, at when projection addressing tab order during each width of cloth picture presentation of quick identification number.From the shooting of film, each section film all is to be spliced by camera lens one by one; From the projection number of pictures, every cinefilm all is made up of sectional continuous background plot; From the time of projection, the segment time span of the continuous background of each section was not waited by tens of minutes by the several seconds; In general each section continuous background plot has at least width of cloth pictures up to a hundred to form, this picture is carried out the mark location in proper order, by in projecting device, increasing certain bits signal identification part or optics bar code information identification component, can be when showing each time by corresponding parts to its addressing location, the method that the signal of addressing can adopt absolute addressing or relative addressing to combine.Picture ordering each mark from the beginning to the end for a certain mirror is J, J+1, J+2 ... J+I, J+I+1, J+I+2 ... J+K; Here J is the initial picture of a certain camera lens, and it is that the preceding paragraph plot and their pixel content of background picture do not have identical basically with the content and the background of a last width of cloth picture.J+K is the last picture of camera lens, and the content of its next width of cloth picture and background do not have identical for next section plot and their pixel content of background picture more than 99%; Among from J to J+K each all has 70% left and right sides public content to the pixel of the background information of adjacent picture, they exist 1/24 second the time difference and the variation that saves of thing and the spatial diversity that brings for some reason when taking, but difference degree thing joint and different for some reason between this adjacent pictures, difference between some adjacent picture seldom, watch two width of cloth pictures that differ greatly respectively for the left and right sides eyes that make spectators, in this section film, make the imaging on the retina of both eyes of the spectators left and right sides of more adjacent a pair of picture.Such as a certain 1/24 second time period, left eye sees that mark is the picture of J+K-4 and right eye sees that mark is the picture of J+K-1, and next 1/24 second time period left eye sees that mark is the picture of J+K-3, and right eye sees that mark is the picture of J+K; And in the 1/24 second time of the next one, left eye is seen the picture of J+K-2, the black picture that right eye is seen, and this moment, the light of right eye projected picture covered light through auxiliary dimmer, and this moment, the moment fusion of right and left eyes vision still produced the J+K-2 image content.
In order to make picture I, I+1, I+2, I+3, the I+4 of a certain camera lens that cinefilm takes ... parallax between adjacent any two pictures meets people's right and left eyes stereopsis information, for the film with 24 width of cloth/speed shooting second, video camera should move to guarantee that 24 pictures of mean allocation are taken viewpoint within the follow shot distance at 65mm * 24=1.56 rice with 1.56 meter per second even velocity on the shooting platform.Certainly this is a kind of desirable state, and the motion conditions of shooting platform can only be selected according to the needs of plot in real film shooting process.Relation for the human eye stereoscopic parallax that picture had adjacent on the translational speed of sending sheet speed, shooting platform of the film of film shooting and the film illustrates by the data in the following table.

Improvement as three-dimensional projection method and apparatus of the present invention, the film that has the binocular stereoscopic parallax information for shooting, it is not to be fixed on for 24 width of cloth/seconds that sheet speed is sent in the projection of film, the sheet speed of sending of film changes at 24 width of cloth/second-60 width of cloth/between second, it send on the numerical information band that the speed data of sheet is recorded in film perforation limit, in the three-dimensional projection chamber, film send sheet speed along with the carrying out in real time of projection, real time altering, make spectators about the parallax of watching as much as possible at 65mm.
When the follow shot platform speed is brought up to 13mm/ (1/24) second promptly during the speed of 3.02 meter per seconds, if the film pick-up machine send the space shooting viewpoint difference between the adjacent picture of the captured picture of sheet speed with 24 width of cloth/seconds be 13mm, standard right and left eyes distance greater than the adult, have only the transfer rate of the photographic film when changing this shooting platform translational speed to become for 48 width of cloth/seconds, when three-dimensional projection device of the present invention was shown, this camera lens adjacent parallax of two pictures on spectators' right and left eyes arbitrarily was 65 millimeters.This section picture is shown as if the speed with 24 width of cloth/seconds when projection, though the stereopsis in the time of truly reducing shooting, but to spectators' displaying is slow motion, with real speed a certain distance is arranged, making the transfer rate of film by the speed that changes the film main driving motor during projection film was 48 width of cloth/seconds, will show the real stereopsis of spectators fully when projection.Therefore, when the speed of follow shot platform is between 1.56 meter per seconds-3.02 meter per second, the distance of the shooting spatial point of sending sheet speed to be adjusted into to make two adjacent width of cloth pictures of film is sent sheet speed for 65mm's, and send sheet speed so that the synchronous speed change during in three-dimensional projection is sent the sheet projection at the perforation limit of film film.
Has effectively relative visual range according to observed concrete object during three-dimensional environment around human eyes are observed.Meeting eyes by the distance of visual sense cell adjacent on the retina in the human eyeball calculates apart from 65mm, the about 1 meter object stereoscopic sensation 371 meters outside of size descends rapidly, because only there is very little parallax in the imaging basically identical of object on people's double eyeball of 1 meter of 371 meters size outward.But human eyes can appreciate again several kilometers and even tens of kilometer range hills and mountains, cloud layer, etc. scene.
When taking the local scenery of teacher outside taking 371 meters by filming apparatus, by zoom lens or long lens camera lens, still can clearly expire picture photographing, still can show the stereoeffect of local scenery outside 371 meters when on three-dimensional projection device of the present invention, showing for the fragment that makes such wide-long shot, the locus difference of viewpoint should be adjusted into hundreds of millimeters during the shooting of the picture that this segment is adjacent, and move film with the speed of 24 width of cloth/second picture, through corresponding calculated then the translational speed of shooting platform should be tens of kilometers/hour.Take several kilometers and during when taking the teacher to the hills and mountains scene of tens of kilometer range and cloud layer, for the parallax that makes adjacent shooting picture satisfies macroscopical stereoeffect of watching when showing, the translational speed of shooting platform also should several hundred kilometers/hour.
When camera is taken around a certain micro-landscape model, as causing the sensation of going sightseeing around true view with the speed ring of 1.56 meter per seconds to spectators, the translational speed of taking the shooting platform of micro-landscape model should be in the ratio of 1.56 meter per seconds divided by the micro-landscape model.Landscape model for 100: 1, the translational speed of shooting platform should be 1.56cm/ second, and the sheet speed of walking on the photographic film was 24 width of cloth/seconds, and the space of adjacent picture shooting parallax is 0.65mm on the film, when passing ratio is converted into true view, then be the 65mm stereoscopic parallax of people's left and right sides eyes.
When same camera carries out complete picture feature shooting to a certain less relatively object, the shooting in the three-dimensional world of the microcosmic that particularly adjusts the telescope to one's eyes down, also can determine the space-time function of adjacent pictures by the parallax calculation method of above-mentioned miniatures, come the three-dimensional world of more real expression microcosmic.
For the bright projector as non-three-dimensional film three-dimensional projection device of this law, the projector by the screen of various planes, torus shape screen and the screen of concave spherical surface shape illustrates respectively respectively.
Kind quantity in the non-three-dimensional film of plane screen (16mm or 35mm or the 70mm) film is maximum, wherein account for the absolute majority of the commercial projection of movie theatre again with the film of 35mm, the non-three-dimensional film overwhelming majority who makes 35mm at present prints by the wide-screen format of standard.Thereby it is different different because of the specification of film as the three-dimensional projector of plane of the present invention screen.
Such as for the non-three-dimensional film three-dimensional projector of 16mm of the present invention plane screen, by increasing the film gate window size, two width of cloth pictures of adjacent position on the film gate can be shown through a big slightly projection lens of bore, by corresponding optical path changing element and polarisation modulating part, make top picture and bottom picture overlap the horizontal displacement coincidence up and down and be projected in the metal screen.Spectators put on polaroid glasses, separate two width of cloth pictures in the screen automatically; Along with the feeding mechanism frame by frame of film is sent picture into film gate, the image part on the eyeball retina of the spectators left and right sides is respectively a pair of picture adjacent on the film, 1/24 second the projection time difference of their existence, activates spectators' stereopsis thus.
Its metal screen is shaped as the cylindrical interior ring of 120 degree or 180 degree or 240 degree or 360 degree for the non-three-dimensional ring screen of the present invention film three-dimensional projector, it is to be shown synchronously by many film movie projectors, one section ring curtain of a smaller angle in each projector projection ring curtain, the area of the side door window of the ring curtain projector that each is synchronous increases and is twice, make the window of film gate corresponding with two width of cloth picture areas on the film, during projection on each film adjacent a pair of picture show simultaneously and be imaged on the ring curtain, spectators put on polaroid glasses, separate the right and left eyes image automatically and make the stereoeffect of Circamara reach more most enjoyable stage circle.
Non-three-dimensional projector as recessed ball screen film, change the recessed spherical screen of recessed spherical screen stereoscopic film into the metal screen, on the film gate of projector, increase an adjacent window, make two windows on the film gate corresponding with two width of cloth picture accurates on the film, at each picture window projection optical axis correspondence position one recessed ball curtain projection lens is housed, makes adjacent two width of cloth pictures while overlapping imaging in the metal screen of concave spherical surface.
In sum, stereopsis projection method of the present invention is simple, the cinefilm of the abundant positive negative parallax that has of adjacent pictures particularly, and its three-dimensional reduction projection is true; For the film of taking according to the conversion and the corresponding method of human left and right sides eyes in time and space, with real three-dimensional identical, when spectators watched, the signal of positive negative parallax was abundant and on the spot in person when adopting three-dimensional projector of the present invention to show; Certainly also be applicable to the three-dimensional projection of most non-stereo film film, the present invention is easy to the improvement of existing projector, re-design simple, for existing universalness, popular film, the three-dimensional projection vision system of non-three-dimensional film all can experience once new trial and exercise when spectators watched each time, produce strong stereoeffect, make the film of same title bring different, excellent more impressions to spectators by different projection means.
Below in conjunction with accompanying drawing and embodiment stereopsis projecting device of the present invention is further described.
