METHOD OF ENCODING THREE-DIMENSIONAL DATA, METHOD OF DECODING THREE-DIMENSIONAL DATA, DEVICE FOR ENCODING THREE-DIMENSIONAL DATA AND DEVICE FOR DECODING THREE-DIMENSIONAL DATA Russian patent published in 2025 - IPC H04N19/124 H04N19/597 

FIELD: physics.

SUBSTANCE: invention relates to encoding and decoding of three-dimensional data. One or more attributes corresponding to a point are encoded and encoded data is generated, wherein the encoded data includes a first set of parameters for the encoded data and one or more attribute data units, wherein each of the one or more attribute data units includes an attribute header, wherein the first set of parameters includes one or more attribute parameters, one or more attribute parameters correspond to said one or more attributes on a one-to-one basis and the attribute header includes a value indicating the order of the attribute parameter corresponding to the attribute data unit, among said one or more attribute parameters stored in the first set of parameters.

EFFECT: high efficiency of encoding attributes relative to a three-dimensional point.
