Point Cloud Encoding Method, Point Cloud Decoding Method, Encoder, and Decoder

摘要

A point cloud decoding method related to the field of coding technologies and includes reconstructing a point cloud comprising one or more patches, wherein the one or more patches comprise a current patch, wherein the reconstructing process includes transforming coordinates (x2, y2) of a second point of the current patch in a second coordinate system to coordinates (x1, y1) of a first point of the current patch in a first coordinate system, wherein the coordinates (x1, y1) of the first point of the current patch in the first coordinate system are obtained based on the coordinates (x2, y2) of the second point of the current patch in the second coordinate system and a transform matrix.
