Abstract
A device for monitoring occupants of seats in a passenger compartment of a vehicle includes a plurality of structured light sources. Each of the plurality of structured light sources is attached to one of a plurality of sections and has an optical element that forms a structured light pattern. The plurality of structured light sources are oriented such that the plurality of structured light patterns, in combination, are directed such that they would cover the occupants of the seats of the vehicle. The plurality of structured light patterns, in combination, are directed such that they would cover all occupants of the seats. A camera is attached to a central niche and is configured to capture image patterns that result from distortion of the plurality of structured light patterns by the occupants of the seats.
