Abstract

See full text

A point cloud encoding and decoding method, an encoder, and a decoder are provided. The encoder determines a processing order of point cloud data during point cloud encoding. The encoder determines a coordinate-axis-order index corresponding to the processing order. The encoder encodes the coordinate-axis-order index and signals encoded bits into a bitstream. The encoder processes the point cloud data according to the processing order, to obtain point cloud data to-be-encoded. The encoder encodes the point cloud data to-be-encoded and signals encoded bits into the bitstream. The encoder determines the coordinate-axis-order index corresponding to the processing order as follows. The encoder sets a value of the coordinate-axis-order index corresponding to the processing order according to a correspondence table between preset indexes and processing orders.
