Abstract

The invention discloses a video encoding and decoding method and device, and relates to the field of 3D video encoding / stereoscopic video encoding. The video coding method comprises the following steps: dividing a current texture frame into a plurality of regions according to depth information to obtain at least one coding block; determining an optimal matching block in texture subframes of othertexture frames with the same or similar depth as the coding block, and calculating a motion vector value according to the coding block and the optimal matching block; and performing inter prediction encoding based on the best matching block and the motion vector value. According to the method, the correlation of the video data in the spatial domain is fully utilized, and the inter-frame retrievalspeed is increased.

Description

technical field [0001] The present disclosure relates to the field of 3D video coding / stereoscopic video coding, and in particular to a video coding method and device. Background technique [0002] Stereoscopic video is a kind of multi-viewpoint video, providing two video signals, corresponding to the left and right eyes of the person respectively, forming a three-dimensional effect. Among them, stereoscopic video has many different representation formats, and the representation format based on "texture + depth" is widely used. [0003] In the representation format based on "texture + depth", two similar data are included, one is two-dimensional video data, and the other is the corresponding depth map. The two-dimensional video data can be encoded and decoded using various existing video encoding and decoding methods, including various standardized technologies such as MPEG2, MPEG4, H.264, H.265, and H.266. [0004] The depth map can also be compressed / decompressed using t...
