Abstract
The present application provides a point cloud encoding method. The method includes: determining a first parameter, where the first parameter is used to indicate a maximum number M of reference points bufferable in a prediction reference buffer, M being a positive integer; determining M reference points based on the first parameter, and storing the M reference points into the prediction reference buffer, and determining an attribute prediction value of a current point based on reference points included in the prediction reference buffer.

A point cloud decoding method, comprising:
- determining a first parameter, wherein the first parameter is used to indicate a maximum number M of reference points bufferable in a prediction reference buffer, M being a positive integer;
- determining M reference points based on the first parameter, and storing the M reference points into the prediction reference buffer;
- and
- determining an attribute prediction value of a current point based on reference points comprised in the prediction reference buffer.
A point cloud encoding method, comprising:
- determining a first parameter, wherein the first parameter is used to indicate a maximum number M of reference points bufferable in a prediction reference buffer, M being a positive integer;
- determining M reference points based on the first parameter, and storing the M reference points into the prediction reference buffer;
