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 2024 - IPC H04N19/124 H04N19/597 

FIELD: physics; data processing.

SUBSTANCE: invention relates to encoding and decoding three-dimensional data. Technical result is provided by encoding fragments of information of attributes of corresponding three-dimensional points using parameters (S6701); and generating a bit stream including encoded pieces of attribute information, control information and pieces of first attribute control information (S6702). Control information corresponds to fragments of attribute information and includes fragments of type information, each of which indicates a type of other attribute information, fragments of first control information of attributes correspond to "one-to-one" fragments of attribute information, and each of the first attribute control information fragments includes first identification information indicating that the first attribute control information is associated with one of the type information fragments.

EFFECT: high efficiency of encoding and decoding information of attributes of a three-dimensional point.
