Abstract: An encoding method includes: obtaining original point cloud data; transforming coordinates of the original point cloud data to obtain a coordinate transformation residual; establishing a relationship between azimuth information of a point cloud and the coordinate transformation residual; determining an encoding rule for the coordinate transformation residual based on the relationship between the azimuth information of the point cloud and the coordinate transformation residual; and encoding the coordinate transformation residual according to the encoding rule, to obtain data rate information.
