THREE-DIMENSIONAL DATA ENCODING METHOD, THREE-DIMENSIONAL DATA DECODING METHOD, THREE-DIMENSIONAL DATA ENCODING DEVICE AND THREE-DIMENSIONAL DATA DECODING DEVICE Russian patent published in 2023 - IPC H04N19/96 H04N19/119 G06T9/00 

FIELD: encoding technique.

SUBSTANCE: invention relates to the field of encoding and decoding three-dimensional data and can find application in a wide range of fields of technology, such as machine vision, which provides autonomous operation of cars or robots, cartographic information, monitoring, infrastructure inspection and video distribution. The method for encoding three-dimensional data includes dividing three-dimensional points included in three-dimensional data into subclouds, including the first subcloud of three-dimensional points and the second subcloud of three-dimensional points (S2631); attaching the first information indicating the space of the first subcloud of three-dimensional points to the header of the first subcloud and attaching the second information indicating the space of the second subcloud to the header of the second subcloud of three-dimensional points (S2632). Fragments of information of attributes of the first three-dimensional points and fragments of information of attributes of the second three-dimensional points are encoded so that these fragments of information are decoded sequentially or in parallel.

EFFECT: reducing the processing time when encoding or decoding three-dimensional data.
