Description
Technical field
The utility model relates to a kind of stereo image shooting and playback system, belongs to electronic technology field.
Background technology
At present, Shi Yong stereo image shooting and playback system mainly contain one-eyed stereo, binocular stereoscopic and compound eye solid.
One-eyed stereo is the characteristics that also can obtain stereoscopic vision according to simple eye, and a pair of anaglyph that camera lens is moved generation successively appears on the screen in turn, send into respectively the people about two, thereby obtain stereoscopic vision.The stereoscopic TV of the type is easy to realize and existing flat-surface television multiple display modes compatible, but stereoscopic vision mechanism according to human eye, allow unit obtain stereoscopic vision, must allow rotating that video camera do not stop around fixed-focus, number of patent application is that 98101085.7 fully compatible flashless time-sharing stereo TV systems of being invented utilize this mode to realize, but this system has proposed too high specification requirement to the photographer, when video camera is static, do not have stereoscopic vision, can not realize the real-time transmission of steric information for the uncertain news spot of scenery focus especially.
Binocular stereoscopic is the direct emulation of people's eyes, utilizes two video cameras separated by a distance that same object is taken a pair of anaglyph, allows two of the people to watch this two width of cloth image to obtain stereoscopic vision respectively by the whole bag of tricks.It is true that this type systematic has scene, the characteristics that third dimension is strong, but, make the stereo-television system of the type be difficult to the compatibility of realization and existing flat-surface television standard because the light path system of two video cameras is relatively independent.
The compound eye solid is to take Same Scene simultaneously with level or steric a plurality of camera, obtain having a plurality of anaglyphs of level or space-time function, realize dividing picture by methods such as cylinder or spheric grating branch look like, any a pair of two width of cloth images with space aberration are sent into two acquisition stereoscopic visions of people respectively, mobile viewing location can see that another to anaglyph, obtains the stereoscopic vision of different azimuth.Adobe company released a kind of many lens stereos camera system of similar insect compound eye in 2007, a plurality of camera lens collection with spatial distribution are contained on the lens assembly exactly, a shared camera fuselage absorbs a plurality of images with space-time function, though the method has reduced the shooting difficulty of compound eye solid, reduced the shooting cost, but still can not guarantee that the position of each anaglyph focus picture on egative film overlaps, if parallax separates not exclusively, can allow the focus picture of anaglyph ghost image occur during reproduction.
The utility model content
The purpose of this utility model just provides a kind of position that can guarantee each anaglyph focal plane picture and overlaps, even parallax separates not exclusively when reappearing stereo-picture, the stereo image shooting and the playback system of ghost image also can not occur on the picture of focal plane.
The technical scheme that the utility model technical problem solves is: a kind of stereo image shooting and playback system, comprise that picture pick-up device, transmission equipment, display device constitute, it is characterized in that: N sub-aperture is installed at the aperture position of picture pick-up device camera lens, replace former aperture, the adjustable size of each sub-aperture, N sub-aperture picked-up N width of cloth stereoscopic parallax image, appoint and get two width of cloth images with horizontal parallax, stereopsis difference image signal is transmitted, changed, restores into to its picture signal by transmission equipment, reappears stereo-picture on the display screen of stereoscopic display device.
Below describe the course of work of the present utility model: N in detail and be 7 sub-apertures of 7 and be labeled as A respectively, B, C, D, E, F, G, be installed in the aperture position of picture pick-up device camera lens, replace former aperture, sub-aperture uses the PDLC liquid crystal light valve to make, sub-aperture size scalable, at one time, same position, not under the situation of dollying equipment, open 7 stereoscopic parallax images of each sub-aperture picked-up respectively, appoint and get two width of cloth images with horizontal parallax, transmit through transmission equipment, conversion restores into three-dimensional image signal, reappears stereo-picture on the screen of stereoscopic display device.Be so specifically: during shooting, subject 1 images on the CCD4 through lens focus, because sub-aperture has different space geometry positions, for each sub-aperture light path and subject different visual angles is arranged, under the situation of dollying equipment not, aperture 2 is under the control of control circuit 5, open each sub-aperture respectively to 7 stereoscopic parallax images of object picked-up, different time sections at constant duration is absorbed 7 tunnel stereoscopic parallax image sequences to the activity scene, be input in the memory 6, be input to anaglyph selecting circuit 7 again, optional two-way image sequence with horizontal parallax, as select sub-aperture A, the image sequence that C forms, anaglyph sequence as the binocular solid television system is used, setting the sub-aperture formation of A image sequence signal L is main signal, this L signal is passed to computing circuit 8 and coding circuit 9, setting the sub-aperture formation of C image sequence signal is R, this signal R is transported to computing circuit 8,8 couples of L of computing circuit, the corresponding frame of R signal, corresponding pixel points is pursued picture point and is asked difference operation, its difference obtains stereo-picture anaglyph signal Q by the correspondence position reorganization, this parallax signals Q has bipolarity, this signal Q is transported to coding circuit 10 to encode, stereo-picture parallax signals behind the coding is as binocular solid television image sub signal, be transported to multiplexer 11, again the signal L behind encoded circuit 9 codings is transported to multiplexer 11 as binocular solid television image main signal and other system signals, be input to chnnel coding again after multiplexing and modulator circuit 12 transmits after modulating, send receiving terminal demodulator circuit 13, signal conveys after demodulation is to demultiplexer 14, through Xie Fuhou, stereoscopic TV main signal L sends into decoding circuit 15 and decodes, sub signal Q enters and sends into computing circuit 17 again after decoding circuit 16 is decoded, obtain signal R, L through computing, the R signal send three-dimensional display 18 to reappear stereo-picture.
The utility model once to defocused, can absorb many stereoscopic parallax images with different parallax characteristics owing to adopt the picture pick-up device of how sub-iris diaphragm structure, reappears on transmission equipment transmission, conversion, the screen of reduction at display apparatus.Therefore have combined and instant, be widely used, third dimension is strong, no ghost image, and system compatibility is good, is easy to transmission, uses advantages such as simple.
