Abstract

There is provided methods and apparatus of encoding/decoding point cloud geometry data sensed by at least one sensor associated with a sensor index. The point cloud geometry data is represented by ordered coarse points occupying some discrete positions of a set of discrete positions of a two-dimensional space, each occupied coarse point is associated with a radius based on a distance of the point of the point cloud from a referential. The encoding/decoding method comprises encoding/decoding (120) a data (I<pred>) representative of a predicting radius (r<pred>), and encoding (130), into the bitstream, a residual radius (r<res>) between a radius (r<1>) associated with an occupied coarse point and the predicting radius (r<pred>).
