Claim 3:
4. The point cloud encoding method according to claim 3, wherein the packing occupancy maps of a global matched patch and a non-global matched patch in the nth frame of point cloud based on locations that are of occupancy maps of at least a portion of global matched patches in the nth frame of point cloud and that are in the occupancy map of the nth frame of point cloud, to obtain the occupancy map of the nth frame of point cloud comprises:
mapping the occupancy maps of the at least a portion of the global matched patches onto an initial occupancy map of the nth frame of point cloud based on the locations that are of the occupancy maps of the portion of or all the global matched patches and that are in the occupancy map of the nth frame of point cloud; and
packing occupancy maps of other patches different from the at least a portion of the global matched patches in the nth frame of point cloud based on the initial occupancy map that is of the nth frame of point cloud and onto which the occupancy maps of the at least a portion of the patches are mapped, to obtain the occupancy map of the nth frame of point cloud.
