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 an azimuthal coding mode providing a series of bits for encoding a coordinate of a point of the point cloud. The method includes: dividing an interval, to which the point coordinate belongs to, into a left half interval and a right half interval; selecting a context based on an apparent angle (AA) representing an interval angle seen from a sensor that captured the point; and context-adaptive binary entropy encoding a bit (b) of the series of bits, into the bitstream, based on the selected context, the encoded bit (b) indicating which of the two half intervals the point coordinate belongs to.
