Abstract
A method of encoding, into a bitstream, point cloud geometry data sensed by at least one sensor associated with a sensor index, includes: obtaining a list of candidate radiuses (L={r}) for a first occupied coarse point (P) having a first sensor index (λ), a first sample index (s) and being associated with a first radius (r); selecting, for the first occupied coarse point (P), a selected predicting radius (r) from the list of candidate radiuses (L={r}); encoding, in the bitstream, a data (I) representative of the selected predicting radius (r) in the list of candidate radiuses (L={r}); and predictively encoding, in the bitstream, a residual radius (r) between the first radius (r) and the selected predicting radius (r).
