Abstract
A point cloud encoding method is provided to improve coding efficiency. The method includes: obtaining global matched patches in N frames of point clouds in a point cloud group; determining M union patch occupancy maps corresponding to M sets, where a union patch occupancy map corresponding to an mth set is a union set of occupancy maps of all global matched patches in the mth set; packing the M union patch occupancy maps to obtain a global occupancy map; packing each of the N frames of point clouds to obtain occupancy maps of the N frames of point clouds; and encoding the N frames of point clouds based on the occupancy maps of the N frames of point clouds.
