1. A point cloud encoding method, implemented in an encoder and comprising:
determining a processing order of point cloud data during point cloud encoding, the processing order indicating a coordinate axis processing order of three-dimensional coordinates of the point cloud data and the point cloud data being all or part of data in point cloud;
determining a coordinate-axis-order index corresponding to the processing order;
encoding the coordinate-axis-order index and signalling encoded bits into a bitstream;
processing the point cloud data according to the processing order, to obtain point cloud data to-be-encoded; and
encoding the point cloud data to-be-encoded and signalling encoded bits into the bitstream, wherein a correspondence table between preset indexes and processing orders comprises:
 
 
 
 coordinate-axis-order index processing order
 
 
 
 0 Z-Y-X order
 
 1 X-Y-Z order
 
 2 X-Z-Y order
 
 3 Y-Z-X order
 
 4 Z-Y-X order
 
 5 Z-X-Y order
 
 6 Y-X-Z order
 
 7 X-Y-Z order.
