Claim 0:
1. A point cloud encoding method, comprising:
obtaining global matched patches of N frames of point clouds of a point cloud group, wherein N≥2 and N is an integer;
determining M union patch occupancy maps corresponding to M sets, wherein each of the M sets comprises N global matched patches having a matching relationship in the N frames of point clouds, wherein a union patch occupancy map corresponding to an mth set in the M sets is a union set of occupancy maps of all global matched patches in the mth set, 1≤m≤M, and both m and M are integers;
packing the M union patch occupancy maps to obtain a global occupancy map used to determine locations of the M union patch occupancy maps in the global occupancy map;
packing occupancy maps of a global matched patch and a non-global matched patch in each of the N frames of point clouds by using the global occupancy map, 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.
