Abstract
An encoding method, a decoding method, and an apparatus are provided. The encoding method includes: determining X first patches from M first patches in a current frame, where there is a matching relationship between the X first patches and X second patches, the X second patches are included in a previous frame of the current frame, X is less than or equal to M, and both X and M are positive integers; obtaining auxiliary information of the X first patches and auxiliary information of X second patches; obtaining X groups of auxiliary information differences based on the auxiliary information of the X first patches and the auxiliary information of the X second patches; and encoding the X groups of auxiliary information differences. The encoding method improves coding performance by using a correlation between point cloud data of two adjacent frame.
