METHOD AND DEVICE FOR ENCODING/RECONSTRUCTION OF POINT CLOUD ATTRIBUTES Russian patent published in 2023 - IPC H04N19/597 G06T7/10 G06T9/00 

FIELD: encoding.

SUBSTANCE: means for encoding and reconstructing a point cloud that displays the outer surface of a 3D object. The bounding box that sets the boundaries of the points in the point cloud is divided into a plurality of sections, and the breakdown depends on the bit depth of the encoder used to encode the points. Encodes data that displays the attributes of a point in a point cloud by linking to the section to which the specified point belongs. Moreover, the 3D coordinates of the breakdown point are encoded as differential coordinates obtained from the coordinates of the reference point of the breakdown of the 2D insert geometry encoded in the image.

EFFECT: increased efficiency of encoding.
