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