Visual angle switching and encoding method and device of multi-viewpoint video

Abstract

The invention discloses a visual angle switching method and device of a multi-viewpoint video, which is used for solving the problems of poorer continuity of a switching picture and larger load of a system when a switching angle is larger in the prior art. The video encoding stream of each visual angle contains a visual angle switching frame transmitted in parallel to a specific video frame; and the visual angle switching frame and the video frame in the same time position with the visual angle switching frame in the video encoding stream of the visual angle adjacent to the visual angle have the same pictures; and the current visual angle is finally switched to a target visual angle successively through each intermediate visual angle according to the visual angle switching started by a user from the current visual angle to the target visual angle, wherein the visual angle switching between any two adjacent visual angles comprises: when the visual angle switching frame of the video encoding stream of a first visual angle reaches, the visual angle switching frame is controlled to be played and switched to a second visual angle in which the video frame with the same pictures to the visual angle switching frame is positioned from the first visual angle. The invention also discloses an encoding method and device of a multi-viewpoint video.

Description

technical field [0001] The present invention relates to the technical field of multi-viewpoint video, in particular to a method and device for viewing angle switching and encoding of multi-viewpoint video. Background technique [0002] Multi-viewpoint video is an important content of video services. It is characterized in that users can freely choose viewing angles, so that they can watch different sides of the object (scene) to be photographed. like figure 1 As shown, the implementation method of multi-viewpoint video is to shoot the same object (scene) from multiple angles during shooting, and the viewing angle numbers in the clockwise direction are 1, 2, 3...16; The video streams of the views are encoded separately to obtain multi-view video encoding streams (including the video encoding streams of each view); during playback, the video encoding streams of the corresponding views need to be decoded and displayed according to user requirements. [0003] Angle switching o...
