Claims9
A method for transmitting point cloud data, the method comprising:
- encoding point cloud data including volumetric data as a bitstream;
- encapsulating the encoded point cloud data and metadata for the encoded point cloud data into a file according to an ISO base media file format(ISOBMFF),
- wherein the metadata includes object information of one or more objects presented in the volumetric data, and the object information includes an object identifier representing an object and object direction information for the object represented by the object identifier,
- wherein the metadata further includes information representing a shape of a point of the point cloud data and information representing a size of the point,
- wherein the shape of the point includes a circle shape,
- wherein the metadata further includes information representing an x component, a y component and a z component of an origin position of a bounding box for the object,
- wherein the metadata further includes information representing an x component, a y component and a z component of a position of a camera related to a viewport, and
- wherein the metadata further includes information representing horizontal and vertical ranges for a Field of View (FoV);
- and
- transmitting the bitstream.
