Methods for encoding and decoding point cloud data, point cloud data decoding equipment, and computer-readable immutable storage media.

Abstract

The invention relates to a method for encoding and decoding matchstick data, a device for decoding matchstick data, and a computer-readable, immutable storage medium. A point cloud data decoding device, for example, includes: memory configured to store point cloud data; and one or more processors implemented in the circuit and configured to: encode the frame of the point cloud data consisting of multiple points, each point linked to position values ​​that determine the corresponding position of the point; determine the global scaling factor for the frame; and scale the position values ​​of each point according to the global scaling factor. The scaling can be used to prevent points from exceeding the boundaries of the corresponding bounding box containing the corresponding points.
