Method and system for detecting a seat occupancy state of a seating arrangement on the basis of radar point clouds

Abstract

A method for the automated detection of a seat occupancy state, in particular related to each seat, of a seating arrangement having at least one seat comprises: receiving or generating measurement data, which represents in each case one assigned radar point cloud for each measurement frame of a sequence of a plurality of temporally consecutive measurement frames, so that the measurement data represent a sequence of radar point clouds corresponding to the sequence of measurement frames, wherein each radar point cloud of the sequence was or is obtained on the basis of a radar scan of a spatial region surrounding at least some sections of the seating arrangement, which takes place at a measurement time or during a measurement period assigned to the respective measurement frame; accumulating a plurality of the radar point clouds of the sequence in order to obtain an accumulated radar point cloud containing radar points from each of the individual radar point clouds combined as part of the accumulating process; determining a seat occupancy state of the seating arrangement on the basis of an evaluation model, which returns, as a function of the accumulated radar point cloud, one of a plurality of predefined possible seat occupancy states of the seating arrangement as an evaluation result; and outputting a piece of information defined according to the evaluation result.
