THREE-DIMENSIONAL POINT CLOUD TRANSMISSION METHOD AND APPARATUS, THREE-DIMENSIONAL POINT CLOUD RECEIVING METHOD AND APPARATUS, AND STORAGE MEDIUM

WIPO Patent Application WO/2022/194309

A1

Provided in the present application are a three-dimensional point cloud transmission method and apparatus, a three-dimensional point cloud receiving method and apparatus, and a medium. The transmission method comprises the following steps: parsing point cloud data of an original point cloud to determine a quality level of a spatial region of a point cloud to be transmitted; according to the quality level of the spatial region of said point cloud, selecting point cloud data in the spatial region of said point cloud to generate a media code stream; determining quality indication information of the spatial region of said point cloud according to the selected point cloud data in the spatial region of said point cloud, and writing the quality indication information of the spatial region of said point cloud into the media code stream; and transmitting the media code stream.
