Abstract
A system to detect occupants is provided. The system may rotate the field of views of multiple sensors in order to scan an area. The system may scan the area multiple times. The system may determine the number of occupants in the area based on a comparison of a scan of the area with a scan of the area when the area is determined to be unoccupied. The system may determine the number of occupants in the area based on a maximum number of occupants detected by any of the sensors. The system may also determine a location of an object or an occupant from scans of the area obtained from multiple sensors.
