Abstract
A point cloud encoding method includes grouping a to-be-coded point cloud group into a plurality of subgroups, where the grouping a to-be-coded point cloud group into a plurality of subgroups includes pre-grouping a plurality of frames of point clouds in the to-be-coded point cloud group to obtain a pre-grouped subgroup, and determining, based on feature information of the pre-grouped subgroup, that the pre-grouped subgroup is one of the plurality of subgroups, where the feature information represents a size of an occupancy map of a point cloud in the pre-grouped subgroup, and encoding a point cloud included in the plurality of subgroups.
