Claims15
A method comprising:
- converting position information of point cloud data along X, Y and Z axes into angular coordinates for an origin of the X, Y, and Z axis based on scale factors;
- encoding geometry data of point cloud data based on an octree;
- encoding attribute data of the point cloud data;
- and
- generating a bitstream including the encoded point cloud data,
- wherein the bitstream includes information related to the scale factors used in conversion for the angular coordinates for the point cloud data,
- wherein the bitstream further includes tile inventory information of a tile for the point cloud data,
- wherein the tile inventory information includes XYZ coordinates of a tile bounding box and a size of the tile bounding box,
- wherein values for each of the angular coordinates are offset based on maximum values related to each of the angular coordinates, and
- wherein the information related to the scale factors are specified for each of the angular coordinates.
