Video coding method, decoding method and related device

Abstract

The invention provides a video coding method, a video decoding method and a related device. The video coding method comprises the steps of: obtaining a multi-view image sequence of a shooting target, wherein the multi-view image sequence comprises images of the shooting target obtained from a plurality of shooting angles at the same moment; and then, according to the sequence of time corresponding to the multi-view image sequence, coding the multi-view image sequence corresponding to the shooting target at each moment in sequence to obtain a multi-view video stream, wherein the multi-view image sequence corresponding to each moment is coded to obtain a multi-view coded image sequence. Therefore, the multi-view coding image sequence at any moment can be independently decoded to obtain the multi-view image at the moment, and the multi-view coding image sequences at other moments do not need to be decoded, so that the decoding burden is reduced. Moreover, the coded images in any multi-view coded image sequence are not all key frames, so that the code rate of the finally obtained multi-view video stream is low, and the network loading burden and the bandwidth resource demand are reduced.

Description

technical field [0001] The invention belongs to the technical field of video coding, and in particular relates to a video coding method, a decoding method and related devices. Background technique [0002] In a multi-camera video shooting scenario, there may be dozens or even more cameras around the central target, that is, videos shot from multiple perspectives. When watching this kind of video, the user can switch the shooting angle of view on a certain screen so as to watch images taken from different angles of view, that is, it can realize free switching between multiple shooting angles of view. [0003] At present, a commonly used encoding method for videos shot from multiple viewing angles is: the images of each shooting angle are encoded into a video file in chronological order, but when the user switches the viewing angle, the video file corresponding to each shooting angle is To start decoding from the most recent I frame, it has been solved to the target image pos...
