Abstract
The present disclosure provides a point cloud decoding method. The point cloud decoding method includes: determining first information corresponding to a current node, wherein the first information is used to indicate whether first-type neighborhood nodes of the current node are valid, and the first-type neighborhood nodes are neighborhood nodes whose geometry information has been decoded; obtaining occupancy information of N neighborhood nodes of the current node based on the first information, N being a positive integer; and performing predictive decoding on planar structure information of the current node based on the occupancy information of the N neighborhood nodes.

A point cloud decoding method, comprising:
- determining first information corresponding to a current node, wherein the first information is used to indicate whether first-type neighborhood nodes of the current node are valid, and the first-type neighborhood nodes are neighborhood nodes whose geometry information has been decoded;
- obtaining occupancy information of N neighborhood nodes of the current node based on the first information, N being a positive integer;
- and
- performing predictive decoding on planar structure information of the current node based on the occupancy information of the N neighborhood nodes.
