Claim 4:
5. The apparatus of claim 2, wherein the second feature information comprises a fourth size of a third occupancy map of a fourth point cloud in the ith pre-grouped subgroup, and wherein the instructions further cause the processor to be configured to:
determine that the ith pre-grouped subgroup is one of the subgroups when a first quantity of frames of large-size point clouds in the ith pre-grouped subgroup is less than or equal to a first preset quantity and when a second quantity of frames of large-size point clouds in the (i+1)th pre-grouped subgroup is greater than the first preset quantity, wherein each of the large-size point clouds comprises a first occupancy map size that is greater than or equal to a second threshold; or
determine that the ith pre-grouped subgroup is one of the subgroups when a first average value of a first ratio of a fifth size that is obtained based on a global matching packing algorithm and that is of the third occupancy map to a sixth size that is obtained based on a candidate packing algorithm and that is of the third occupancy map is less than or equal to a third threshold and when a second average value of a second ratio of a seventh size that is obtained based on the global matching packing algorithm and that is a fourth occupancy map of a fifth point cloud in the (i+1)th pre-grouped subgroup to an eighth size that is obtained based on the candidate packing algorithm and that is of the fourth occupancy map is greater than the third threshold.
