The invention provides a video data transmission method and transmission device based on video stream data, and the method comprises the steps: obtaining three-dimensional data information of a target video, the three-dimensional data information comprising a triangular mesh set and a vertex coordinate set of a three-dimensional model; 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; encoding the topological relation and the vertex coordinates 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 invention relates to the field of video data processing, in particular to a video data transmission method, device and storage medium based on video stream data. Background technique [0002] With the development of science and technology, people have higher and higher requirements for various image resources. In order to create an immersive feeling for users, more and more image resources adopt volumetric video technology. Volumetric video is a kind of A technology that captures information in three-dimensional space (such as depth information and color information, etc.) and generates a sequence of three-dimensional models. These three-dimensional models are connected to form a new video format that can be viewed at any angle. [0003] Since the volumetric video is essentially a series of continuous 3D model sequences, the data occupied by the volumetric video is relatively large, and it is difficult to transmit data in the existing network envir...
