Research On The Technology Of Stereo Picking Up Images And Display

With the development of the imaging technology and computerprocessing technology, the two-dimensional picture can not be satisfied bypeople who pursue the stereoscopic vision. Especially in the field of medicine,the request of display system which is used in operation is enhancedincreasingly. So the research and development of stereo picking up imagesand display technology is impelled. This paper is designed to be a whole setof stereo picking up images and display system precisely in view of this kindof demand with the aid of stereo television technology achievement andcombining the computer stereo display technology.In this paper, the fundamental of stereoscopic vision and the realizationmeans is introduced briefly. It is discussed in detail that using of the doubleCCD picking up images system and the hardware realization method ofstereo images forming and processing system.Under the microprocessor CPUcontrol, it completed video signal processing technology through the I~2C mainline. And though the method of memory and the low speed stores and highspeed takes out,it compressed the video signal field cycle 20ms into10ms.Two groups video signals will separately pass through the D/Aconverter and the latter level video signal processing again,and applicatetime-system principle synthesising three-dimensional signal,the picture willachieve the three dimensional effect. Then the stereo feeling is gained by theobserver through combining the LCD modulation screen with the passivepolarized glasses.This technology has reached to the applied degree and been used inmedical appliance at present. It can be used not only in the stereo observationbut also in the project detection. And it has the much application foregroundin the field of video entertainment and education.
