ENCODING AND DECODING OF LIDAR DATA FRAMES

Abstract: encoding and decoding of lidar data frames is presented, and in particular to entropy coding of lidar data wherein the context models used depend on the order in which the lidar sensor receives the lidar return signals. for example, an indication whether a lidar return signal with a particular index having a value i, 1≤i≤y, corresponding to a sequential order based on a time of arrival of lidar return signals of the emitted ray, may be encoded as an entropy coded bit using a distinct context model for each possible value i of the index.
