FIELD: data processing.
SUBSTANCE: invention relates to encoding and decoding geometric data of a point cloud detected by at least one sensor. Method includes encoding (110), into a bit stream, data (Snext) indicating whether occupied coarse point (Pnext), corresponding to a point of the point cloud, is a lagging occupied coarse point, wherein occupied coarse point is considered delayed occupied coarse point (Pnext), if its index in lexicographic order is less than index of first reference coarse point (Pref), corresponding to previously coded point cloud of points. Occupied coarse point is the registered point of the cloud of points which is determined from one index s of the count corresponding to the time of measurement along the measurement path, and one index of the sensor corresponding to the sensor.
EFFECT: high encoding efficiency.
