Abstract


The rapid development of multimedia technology , three-dimensional video multimedia technology is one of the hot spots. Stereoscopic video based on the observed number of viewpoints can be divided into binocular stereo video and multi- view stereo video . Which binocular stereoscopic video is divided into parallel and convergent camera system. Discussed in this article binocular stereoscopic video system is parallel camera system. First introduced the human visual system to analyze the human visual characteristics as well as the human eye parallax principle , which is the compression and theoretical principles of stereoscopic shooting . The second section describes the MPEG-2 video coding standard , including system architecture , encoding method , and the \Time using the MPEG-2 motion compensation prediction can be combined with graded and realize stereoscopic disparity compensated predictive encoding scheme , and proposed the enhancement layer frame structure using bidirectional prediction encoding. Disparity estimation algorithm for stereo matching is a critical step , common stereo matching algorithm matching algorithm can be divided into global and regional matching algorithm. Regional matching algorithm is relatively simple, more applications , in which each pixel within the block and the absolute error (SAD) template matching algorithm to determine the match after fast, but prone to mismatch phenomenon . SAD comparison algorithm , each pixel block of the absolute and differential error (SSAD) algorithm is improved to some extent the accuracy of the matching , and achieved accurate disparity map . In the three-dimensional display, the common way to bright points method , time division method , the color of law . Optical method has high cost disadvantage of fixed viewpoint , time division method exist \The division method and the color of the Combination , according to complementary programs and field frequency division line frequency division by complementary software program and proposed a new division multiplier field image and complementary programs to be implemented .
