Abstract
A three-dimensional data encoding method includes: dividing a current frame including three-dimensional points into processing units; and encoding the processing units to generate a bitstream. Control information for each frame included in the bitstream includes first information indicating whether (i) one of the processing units included in the current frame includes duplicated points that are three-dimensional points having same geometry information or (ii) none of the processing units includes the duplicated points.
Claims8
A three-dimensional data encoding method, comprising:
- dividing a current frame including three-dimensional points into processing units;
- and
- encoding the processing units to generate a bitstream,
- wherein control information for each frame included in the bitstream includes first information indicating whether (i) one of the processing units included in the current frame includes duplicated points that are three-dimensional points having same geometry information or (ii) none of the processing units includes the duplicated points.
A three-dimensional data decoding method, comprising:
- obtaining a bitstream generated by encoding processing units into which a current frame including three-dimensional points is divided;
- and
- decoding the processing units from the bitstream,
- wherein control information for each frame included in the bitstream includes first information indicating whether (i) one of the processing units included in the current frame includes duplicated points that are three-dimensional points having same geometry information or (ii) none of the processing units includes the duplicated points, and
- the decoding of the processing units from the bitstream includes decoding the processing units using the first information.
A three-dimensional data encoding device, comprising:
- a processor;
- and
- memory,
- wherein using the memory, the processor:
- divides a current frame including three-dimensional points into processing units;
- and
- encodes the processing units to generate a bitstream,
- wherein control information for each frame included in the bitstream includes first information indicating whether (i) one of the processing units included in the current frame includes duplicated points that are three-dimensional points having same geometry information or (ii) none of the processing units includes the duplicated points.
A three-dimensional data decoding device, comprising:
- a processor;
- and
- memory,
- wherein using the memory, the processor:
- obtains a bitstream generated by encoding processing units into which a current frame including three-dimensional points is divided;
- and
- decodes the processing units from the bitstream,
- wherein control information for each frame included in the bitstream includes first information indicating whether (i) one of the processing units included in the current frame includes duplicated points that are three-dimensional points having same geometry information or (ii) none of the processing units includes the duplicated points, and
- in the decoding of the processing units from the bitstream, the processing units are decoded using the first information.
