Passenger detection device in vehicle, especially car, has at least two image recording devices, and detection devices which detect occupation of seat based on measured distance to seat

摘要

The device includes at least two image recording devices (21, 22) arranged at a predetermined distance, and measuring devices (6-9) for measuring distance (a) to object (20) based on at least two recorded images. Devices (33, 34) provide reference data concerning the distance of the image recording devices to a seat (31, 32) according to the position of the seat. Detection devices (10-12) detect an occupation of the seat based on the distance measured through the measuring devices and the reference data.
