Abstract

The invention discloses a multi-view video data processing method and device and a storage medium, and the method comprises the steps that when the viewpoints of display equipment are switched, the display equipment sends a switched target viewpoint to decoding equipment; and the decoding equipment provides an image of a slave viewpoint corresponding to a target viewpoint intercepted from a slave image frame in the slave image frame sequence for the display equipment, so that the display equipment displays a viewpoint picture of the low-resolution target viewpoint, and when a picture switching condition is met, the display equipment sends a picture switching condition meeting instruction to the decoding equipment, and the decoding equipment provides an image in a main image frame sequence corresponding to the target viewpoint and / or an image of a slave viewpoint corresponding to the target viewpoint intercepted from the slave image frame for the display equipment according to the picture switching condition satisfaction instruction, so that the display equipment displays a high-resolution viewpoint picture of the target viewpoint. According to the invention, the video can be quickly recovered from low resolution to high resolution after viewpoint switching, and the definition when the video is watched for a long time is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a multi-viewpoint video data processing method, device and storage medium. Background technique [0002] The free viewpoint technology is a technology for viewing videos from a free viewpoint. The current free-viewpoint application using the free-viewpoint technology can allow viewers to watch videos in the form of continuous viewpoints within a certain range. The viewer can set the position and angle of the point of view, and is no longer limited to watching a video shot by a fixed camera angle of view, realizing a 360° free viewing angle to watch the video. [0003] The current free-viewpoint applications often use the spatial stitching method to splice single-channel videos from multiple viewpoints together. When the user switches viewpoints on the free-viewpoint application side, the free-viewpoint application stitches together multiple viewpoints. Single-ch...
