Abstract
(EN)
A point cloud data transmission method, according to embodiments of the present invention, comprises the steps of: generating a geometry image related to a location of point cloud data; generating a texture image related to an attribute of a point cloud; generating an occupancy map related to a patch of the point cloud; generating auxiliary patch information related to the patch of the point cloud; and/or multiplexing the geometry image, the texture image, the occupancy map, and the auxiliary patch information. A point cloud data reception method, according to embodiments of the present invention, comprises the steps of: demultiplexing a geometry image related to a location of point cloud data, a texture image related to an attribute of a point cloud, an occupancy map related to a patch of the point cloud, and auxiliary patch information related to the patch of the point cloud; decompressing the geometry image; decompressing the texture image; decompressing the occupancy map; and/or decompressing the auxiliary patch information.
