Claim 0:
1. An apparatus comprising:
a memory configured to store instructions; and
a processor coupled to the memory, wherein the instructions cause the processor to be configured to:
group a to-be-coded point cloud group into a plurality of subgroups by:
pre-grouping a plurality of frames of first point clouds in the to-be-coded point cloud group to obtain a pre-grouped subgroup; and
determining, based on first feature information of the pre-grouped subgroup, that the pre-grouped subgroup is one of the subgroups, wherein the first feature information represents a first size of a first occupancy map of a first point cloud in the pre-grouped subgroup;

encode a second point cloud comprised in the subgroups;
pre-group, for an ith time and using a jth frame of point cloud as a start point, second point clouds that are not grouped in the to-be-coded point cloud group to obtain an ith pre-grouped subgroup, wherein the jth frame of the point cloud is a first frame of point cloud in the second point clouds, wherein i is an integer greater than or equal to 1, wherein j is an integer greater than or equal to 1, and wherein the ith pre-grouped subgroup comprises one or more frames of the second point clouds starting from the jth frame of the point cloud;
obtain second feature information of the ith pre-grouped subgroup; and
determine, based on the second feature information, that the ith pre-grouped subgroup is one of the subgroups.
