  • Publication number: 20250056041
    Abstract: A method of encoding, into a bitstream, point cloud geometry data sensed by at least one sensor associated with a sensor index is provided, the point cloud geometry data being represented by ordered coarse points occupying some discrete positions of a set of discrete positions of a two-dimensional space, each coarse point being located within the two-dimensional space by an order index defined from a sensor index associated with a sensor that is able to sense a point of the point cloud represented by the coarse point and a sample index associated with a sensing time instant at which the point of the point cloud is sensed. The method includes: obtaining sensing coverage data (SCD) representative of at least one range of order indexes associated with sensed data; and encoding the sensing coverage data (SCD) into the bitstream.
