Abstract： |
Characters of the invention are that video sequence codes of each viewpoint are divided into I frame, P frame and SW frame. In each image set, first frame is I frame, and then multiple P frames and SW frames. H.264 standard is adopted to encode and decode I frame, and P frames, and SW frames are as viewpoint switch frames. When encoding SW frames, the invention carries out motion estimation and entropy coding for SW frame and previous frame in sequence so as to obtain bit stream of motion vectors. Carrying out displacement estimation and entropy coding for SW frame and video frame at same position of adjacent viewpoint, the invention obtains bit stream of displacement vectors between viewpoints. After carrying out transforms, quantification, dividing into bit planes, and channel encoding, the invention obtains bit stream of verification information. At decoding end, SW frames are rebuilt by the invention. |
