Abstract
A point cloud data processing method according to embodiments may comprise a step of encoding and transmitting point cloud data, wherein said encoding comprises encoding a geometry indicating the positions of one or more points of the point cloud data, the step of encoding a geometry further comprises a step of generating an octree of the geometry, and a step of encoding attributes of the one or more points comprises the steps of: generating Morton codes of the one or more points; and rearranging the one or more points on the basis of the octree to generate one or more levels of detail (LOD). The point cloud data processing method according to embodiments may comprise receiving and decoding point cloud data.
Claims15
A method of encoding point cloud data by an apparatus, the method comprising:
- encoding a geometry representing a position of one or more points of the point cloud data;
- and
- encoding an attribute of the one or more points of the point cloud data,
- wherein the encoding the attribute includes generating levels of detail of the one or more points, and searching a neighbor point in the levels of detail based on a search range,
- wherein a shift value is used to the search range.
An apparatus for encoding point cloud data, comprising:
- at least one processor;
- and
- at least one memory storing instructions thereon that, when executed by the at least one processor, cause the apparatus to perform at least:
- encode a geometry representing a position of one or more points of the point cloud data;
- and
- encode an attribute of the one or more points,
- generate levels of detail of the one or more points, and
- search a neighbor point in the levels of detail based on a search range,
- wherein a shift value is used to the search range.
A method of decoding point cloud data by an apparatus, the method comprising:
- receiving a bitstream including point cloud data;
- decoding a geometry representing a position of one or more points of the point cloud data;
- and
- decoding an attribute of the one or more points of the point cloud data,
- wherein the decoding the attribute includes generating levels of detail of the one or more points,
- searching a neighbor point in the level of details based on a search range,
- wherein a shift value is used to the search range.
An apparatus for decoding point cloud data, comprising:
- at least one processor;
- and
- at least one memory storing instructions thereon that, when executed by the at least one processor, cause the apparatus to perform at least:
- receive a bitstream including point cloud data;
- and
- decode a geometry representing a position of one or more points of the point cloud data;
- and
- decode an attribute of the one or more points,
- wherein the decoding the attribute includes generating levels of detail of the one or more points,
- search a neighbor point in the level of details based on a search range,
- wherein a shift value is used to the search range.
