Abstract

The invention provides a video data transmission method and device based on key frames. The method comprises the following steps: acquiring three-dimensional data information of a target video; determining a first reference triangular mesh in the triangular mesh set; according to the boundary of the first reference triangular mesh and the position relationship between the first reference triangular mesh and other triangular meshes, constructing a topological relationship between the triangular meshes in the triangular mesh set; marking key frames and non-key frames of the target video based on texture changes of pictures in the target video; encoding the topological relation, the vertex coordinate code, the marked key frame and the marked non-key frame into a character string in a preset format, and storing the character string obtained by encoding into video stream data of the target video to obtain target video stream data; and when a data transmission operation triggered for the target video is received, sending the target video stream data to a data receiving end.

Description

Technical field [0001] The present invention relates to the field of video data processing, and more particularly to a video data transmission method, device, and storage medium based on a key frame. Background technique [0002] With the development of technology, people's requirements for various image resources are increasing, in order to create an immersive feeling, more and more image resources use volume video technology, volume video is a kind of Capture information in three-dimensional space (such as deep information and color information, etc.) and generate three-dimensional model sequence, which connects to a new video format that can be viewed in any viewing angle. [0003] Since the volume video is essentially a series of continuous three-dimensional model sequences, the data occupied by volume video is large, and it is difficult to data transmission in an existing network environment. [0004] Therefore, there is a need to provide a video data transmission method and...
