Abstract
A method of encoding a point cloud into a bitstream of encoded point cloud data representing a physical object is provided. The method includes: encoding, into the bitstream, azimuthal angle data (ϕcoded,n) representative of an azimuthal angle (ϕ(Pn)) responsive to a capture angle of a sensor that captured a point of the point cloud, wherein the encoding is based on a boundary value (B) that depends on sensor characteristics, and an absolute value of the azimuthal angle data (ϕcoded) is bounded by the boundary value.
Claims21
A method of encoding a point cloud into a bitstream of encoded point cloud data representing a physical object, comprising:
- encoding, into the bitstream, azimuthal angle data (ϕcoded,n) representative of an azimuthal angle (ϕ(Pn)) responsive to a capture angle of a sensor that captured a point of the point cloud, wherein the encoding is based on a boundary value (B) that depends on sensor characteristics, and an absolute value of the azimuthal angle data (ϕcoded) is bounded by the boundary value.
A method of decoding a point cloud, from a bitstream of encoded point cloud data representing a physical object, comprising:
- decoding, from the bitstream, azimuthal angle data (ϕcoded,n) representative of an azimuthal angle (ϕ(Pn)) responsive to a capture angle of a sensor that captured a point of the point cloud, wherein the decoding is based on a boundary value (B) that depends on sensor characteristics, and an absolute value of the azimuthal angle data (ϕcoded,n) is bounded by the boundary value (B).
(canceled)
An apparatus of encoding a point cloud into a bitstream of encoded point cloud data representing a physical object, comprising one or more processors configured to:
- encode, into the bitstream, azimuthal angle data representative of an azimuthal angle responsive to a capture angle of a sensor that captured a point of the point cloud, wherein encoding the azimuthal angle data is based on a boundary value that depends on sensor characteristics, and an absolute value of the azimuthal angle data is bounded by the boundary value.
