Planar mode in octree-based point cloud coding

Abstract:

Method and devices for coding point cloud data using a planar coding mode. The planar coding mode may be signaled using in a planar mode flag to signal that a volume is planar. A planar volume has all of its occupied child nodes on one side of a plane bisecting the volume. A planar position flag may signal which side of the volume is occupied. Planarity may be determined and signaled with respect to a horizontal plane, vertical plane, or otherwise. Occupancy bits may be inferred as a result of planar coding mode signaling.
