The real-time stereo-image display system also comprises a left optical wedge and a right optical wedge; the front surfaces of the left optical wedge and the right optical wedge are respectively towards the left part and the right part of the exit end of the display; and the back surfaces of the left optical wedge and the right optical wedge are respectively pasted with the P-ray polaroid sheet and the S-ray polaroid sheet. The real-time stereo-image display system has strong real time, simple structure and low cost, is easy to operate, can effectively avoid the image interference between the left eye and the right eye and can greatly improve the stereo-effect of images; The utility model is widely used in the fields with critical requirement on the real time and the accuracy, such as medical operation, remote operation, on-orbit servicing, etc.
Description
Technical field
The utility model relates to real-time stereo display technique field, specifically relates to a kind of real-time stereo images display system
Background technology
Now current stereo-picture obtains with showing generally to separate and carries out, it is right at first to take acquisition set of diagrams picture with stereoscopic camera, but next add the stereo display of aid or the free stereo demonstration of bore hole no matter be, most important all is to further handling to the stereo-picture that obtains, such as common color separation technology, it makes the light of some color only enter left eye, and the light of another part color enters right eye, but prerequisite is that necessary stereoscopic image is to painted respectively.Same free stereo will utilize software that image is inserted divisional processing in showing, show by the auto-stereoscopic display that has added grating again, not only the complex manufacturing technology cost is high for these technology, and real-time is not high, uses in the exigent three-dimensional display system of real-time obviously and does not obviously reach requirement.
So be necessary to design a kind of real-time performance height, simple in structure, the three-dimensional display system that price is suitable.
The utility model content
There is the not problem of high cost costliness of real-time in the utility model at three-dimensional display system commonly used, designs a kind of real-time stereo images display system of moderate cost.
The technical solution of the utility model is as follows:
A kind of real-time stereo images display system, include two stereo cameras and display, it is characterized in that: the binocular interval that the centre distance of described two stereo camera camera lenses is behaved, described two stereo cameras link to each other with described display by data line respectively, the left-half of described display exit end is pasted with the p light polarization plate, and the right half part of display exit end is pasted with the s light polarization plate; Also include left and right wedge, towards the left and right part of described display exit end, the back side of described left and right wedge is pasted with p light polarization plate, s light polarization plate respectively respectively in the front of described left and right wedge.
Described real-time stereo images display system is characterized in that: the place ahead of described two stereo camera camera lenses is placed with object.
Described real-time stereo images display system is characterized in that: the eyes of behaving in the rear of described left and right wedge.
According to system requirements, by two optical center distance stereoscopic cameras identical with people's binocular interval, at the same focal length, aperture, aim at same target under the situation of shutter and expose simultaneously that to obtain image right, the image of stereoscopic camera handle acquisition is to showing on regular display then, left-eye image shows display left side part, eye image shows at the display right half part, part is respectively posted p light and s light polarization plate about display surface, corresponding polaroid is also posted on the surface of same wedge, in order to stop the string shadow.The end that the left eye wedge approaches is last, the end that right eye approaches is following, when left eye sees through the left figure of wedge observation display, when right eye is crossed the right figure of wedge observation display, because refraction action, two actual, and what see is the two figure virtual images that coincide with the centre position, owing to the vision difference of two images produces stereoscopic vision.
The beneficial effects of the utility model:
The utility model real-time type is strong, and is simple in structure, cheap, simple, effectively removed the right and left eyes picture crosstalk, improved the stereoeffect of image greatly; The utility model can be applied in medical operating widely, and straighforward operation is in real-time and the strict fields of degree of accuracy such as rail services.
Description of drawings
Fig. 1 is that stereoscopic camera obtains stereo-picture to synoptic diagram.
Fig. 2 half and half shows the binocular images synoptic diagram respectively about regular display.
Fig. 3 is that the virtual three-dimensional image shows synoptic diagram.
Embodiment
Referring to Fig. 1,2,3, a kind of real-time stereo images display system, include two stereo cameras 1,2 and display 4, the binocular interval that the centre distance of two stereo camera 1,2 camera lenses is behaved, two stereo cameras 1,2 link to each other with display 4 by data line respectively, the left-half of display 4 exit ends is pasted with p light polarization plate 15, and the right half part of display 4 exit ends is pasted with s light polarization plate 16; Also include left and right wedge 19,18, the front of left and right wedge 19,18 is respectively towards the left and right part of display 4 exit ends, and the back side of left and right wedge 19,18 is pasted with p light polarization plate 20, s light polarization plate 21 respectively.
The place ahead of two stereo camera 1,2 camera lenses is placed with object 3; The eyes of behaving in the rear of left and right wedge 19,18 22,23.
Below in conjunction with accompanying drawing the utility model is further described:
Stereoscopic camera 1 and 2 pairs of objects 3 are taken as shown in Figure 1, right to obtain stereo-picture, two camera optical centers distance is identical with people's binocular interval, about 65mm, two cameras are at focal length, under the identical situation of aperture object 3 is exposed simultaneously, form the image that parallax is arranged of same object in the camera the inside respectively.Resolution of video camera is 800*600. in this system
Camera is transferred to display to image by specific interface as shown in Figure 2, and what simultaneously the display left-half showed is left-eye image, i.e. left side video camera pictures taken, and in like manner, what the display right half part showed is eye image, promptly right video camera photographic images.Among Fig. 24 is exactly display, and its resolution is 1600*1200, and 5 is left-eye image, and 6 is eye image, and resolution all is 800*600, and display 4 left parts post the p light polarization plate, and right part posts the s light polarization plate.Left and right image emergent ray becomes linearly polarized light respectively through polaroid separately.
As shown in Figure 3,15,16 represent p light and s light polarization plate respectively, and light becomes p and s linearly polarized light respectively by polaroid, and 10,11 all is linearly polarized light, but the polarization direction is vertical, shown among Fig. 3 24 and 25.Available light becomes the vertical linearly polarized light of direction of vibration later on by polaroid.To disturb and the string shadow in order removing, post p light and s light polarization plate equally after wedge 19 and 18, be 20 among Fig. 3 and 21,20 and 21 and stop that light 7 and 8 enters left eye 22 and right eye 23, to avoid causing the phase mutual interference, the image stereoeffect weakens.Light 11 and 10 is by wedge because the refraction action of wedge, two soon to be the two figure virtual images that coincide with the centre position, 13 pass through the virtual image that eye-observations that polaroids are become with wedge arrive for left and right sides image 14 and 17.
