1. A method, comprising:
acquiring reference-frame point cloud data and current-frame point cloud data;
performing two-dimensional regularized plane projection on the reference-frame point cloud data to obtain a first two-dimensional projection plane structure;
performing two-dimensional regularized plane projection on the current-frame point cloud data to obtain a second two-dimensional projection plane structure;
performing motion compensation and encoding on one or more pieces of first two-dimensional graphic information obtained based on the first two-dimensional projection plane structure and one or more pieces of second two-dimensional graphic information obtained based on the second two-dimensional projection plane structure to obtain bit stream information of the current-frame point cloud data, wherein the first two-dimensional graphic information comprises a first geometric information graph and the second two-dimensional graphic information comprises a second geometric information graph; and
repeating the foregoing steps to encode a plurality of frames of a point cloud sequence.
