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 coding blocks according to depth information; determining a candidate matching block from a plurality of coding blocks with the same or similardepths of the coding blocks, and determining an optimal matching block from the candidate matching block; performing intra prediction coding based on the best matching block. The method is low in requirement for the calculated amount, and the compression efficiency is improved.

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 and decoding 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 (texture image / video data), and the other is the corresponding depth map. Two-dimensional video data (texture image) can be encoded and decoded by various existing video codec methods, including various standardized technologies such as MPEG2, MPEG4, H.264, H.265, and H.266. Among the various existing standa...
