Description

Three-dimensional imaging technical apparatus

The utility model provides a kind of three-dimensional image forming apparatus, and it is applicable to departments such as teaching, scientific research, also can be used for fields such as public security, traffic, building, archaeology, physical culture, historical relic.

The method of obtaining exploded view at present has holographic photography, the special-purpose stereocamera photography of parallel double camera lens or general camera two-shipper twocouese to take synchronously.Adopt said method equipment complexity, complex operation, be difficult for grasping, photography conditions is strict simultaneously, is difficult to promote the use of.Continuous development along with science and technology, the modern educational method and the means of education are more and more to imagery, visualize development, existing wall chart and projection display apparatus, it all is good image plane, do not satisfy the requirement of modern education, particularly medical teaching etc. needs the unit and the specialty of sample education, owing to be subjected to restrictions such as sample source, making and preservation condition, the teaching means of more and more wishing to obtain by new approach imagery, visualize.When watching the stereopsis film, be with polarising glass, also to add polaroid before the projector, just can restore into the object former state.This viewing method is shown condition restriction, can not carry projection equipment, watches relatively difficulty of stereopsis film.

The purpose of this utility model provides a kind of device of three-dimensional imaging, and it is compact conformation, easy to use not only, and image definition, well arranged, stereoeffect significantly, low cost of manufacture.

The purpose of this utility model is achieved in that the refraction principle that utilizes light makes the stereoscopic photograph camera lens, be installed on the standard lens of various cameras, take into three-dimensional image film, utilize the reflection of light principle to make stereoscopic viewer then, the stereopsis film is reduced into the object former state, reproduces the object that the stereoscopic photograph camera lens is taken the photograph with strong stereoscopic sensation.The pressure cover of stereoscopic photograph camera lens, lens barrel, camera connected body are dressed up one by thread set.Utilize positioning stud to be hinged with two semi-rings that clamp achromatic prism on the lens barrel barrel, each semi-ring all is fixed with the adjustment bolt.Adjust bolt and utilize inwall to be shaped on the rotation of spiral fluted adjustment ring, in the open slot of lens barrel wall, move, the achromatic prism that is clamped on the semi-ring is rotated around positioning stud.Achromatic prism grinds to form the wedge shape mirror by two blocks of optical glass with unlike material and forms through gummed, and utilizes compressing tablet and trip bolt to be clamped on the semi-ring.Sight glass is made of the eyepiece and the catoptron that are assembled in the upper and lower casing.Catoptron adopts the surface vacuum aluminum plating process to handle, to improve its reflectivity.

Because the utility model three-dimensional image forming apparatus is to adopt to form with phtographic lens and sight glass easy to carry, maneuverable that various cameras are used, the method that has changed traditional shooting and watched stereo film, so need not Special Training, operating personnel just can use, needn't change structure, the performance of camera and can obtain desirable stereoscopic photograph film, as long as film is put into sight glass, the object that can take the photograph phtographic lens truly, well arrangedly reproduces its shape.Because of the achromatic prism in the phtographic lens of this device, can rotating certain angle by adjusting ring, so that the object of various object distances keeps constant phase place, so this device not only is suitable for taking static scenes, also be suitable for taking dynamic scenery, can take the photograph middle scape far away, can take the photograph close shot again, be not subjected to restrictions such as place, time, can reflect the real features of objective object vivid, exactly, solved the problem of some 3 D stereoscopic images that in the photo of plane, can't reflect.Particularly it is applied in teaching, the public security photography on crime work, more the stereoeffect that can obtain giving prominence to.

Describe concrete structure of the present utility model and working condition in detail according to Fig. 1～7.This device is dimerous by phtographic lens and sight glass.Wherein the pressure cover 1 of phtographic lens, lens barrel 2, the connected body 10 that can cooperate with various camera lens is dressed up one by thread set.Between pressure cover 1 and lens barrel 2, cover glass 11 is housed.At lens barrel 2 excircles, be set with rotatable adjustment ring 5.Utilize positioning stud 9 to be hinged with two semi-rings 6 that clamp achromatic prism 12 on lens barrel 2 barrels, each semi-ring 6 all is fixed with adjusts bolt 7.Adjusting bolt 7 utilizes inwall to be shaped on the rotation of spiral fluted adjustment ring 5, in the open slot of lens barrel wall, move along slotted eye, make the achromatic prism 12 that is clamped on the semi-ring 6 around positioning stud 9 rotating certain angle, so that make the object of various object distances keep constant phase place, improve the stereoeffect of image.For eliminating chromatic dispersion, achromatic prism 12 adopts optical glass K ₉And F ₃Grind to form wedge shape, be bonded together with the optics epoxide-resin glue again.Utilize compressing tablet 4 and trip bolt 8 that the achromatic prism 12 that composes is clamped on the semi-ring 6.For light leak between two achromatic prisms that prevent to rotate, be stained with the shading silk fabric betwixt, to guarantee the color difference eliminating effect.The shell of the sight glass of this device is that the upper shell 13, the lower house 14 that are made of plastics combine.At the housing internal fixation frosted glass 15 is arranged, utilizes location-plate 16 to be fixed with reflecting optics 17(position as shown in Figure 4) and the eyepiece 18 that is placed on the viewport place.Reflecting optics 17 adopts the surface vacuum aluminum plating process to handle, and eyepiece 18 utilizes general monolithic planar lens.After lower house 14 interpolations install eyepiece 18, reflecting optics 17, location-plate 16, frosted glass 15, upper shell 13 is got togather, reinforce with holding screw 19 then and be assembled into one.Wherein utilize fixing two reflecting optics 17 of location-plate 16 must guarantee to be in orthogonal state, the reflection angle that is to say each reflecting optics 17 is 90 ° ± 1 '.

During operation, the camera connected body 10 of phtographic lens is installed on the standard lens 21 of camera, keeps achromatic prism to be in vertical position, ring 5 is adjusted in rotation rotates achromatic prism, make the two identical images that form on the film 20 aim at the graduation groove of view finder, promptly photographic.Then in the crack that the film produced 20 is inserted between sight glass frosted glass 15 and the location-plate 16, make sight glass face toward natural light and just can make things convenient for, clearly observe the three-dimensional image that has been reduced.The principle of work of phtographic lens and sight glass such as Fig. 6, shown in Figure 7.Phtographic lens is the refraction principle that utilizes light, makes an object by behind two achromatic prisms 12, forms two same image and takes the photograph on film 20.To produce good image film 20 again and put into the sight glass that utilizes the reflection of light principle to make, utilize natural light, and make by reflecting optics 17 twice of two same image on the film 20 be reflected into erect image.Utilize people's binocular vision mechanism and width of cloth concentrate around one point, as spokes on acis regulatory function, object that phtographic lens is taken the photograph is reproduced truly.
