Smart parking system monitors parking lot occupancy

摘要

Cambridge Consultants Analog Devices has developed a smart parking system to monitor and optimize traffic flow within parking lots. The system combines cameras integrated into a Blackfin Low-Power Imaging Platform (BLIP2) processing platform. BLIP2 features two im-agers, a 640 × 480 OVM7692 SoC sensor with integrated lens from OmniVision and a 640 × 480 CMOS NTSC/PAL ASX340 from ON Semiconductor. An algorithm from Cambridge Consultants is used to calculate which parking spaces are occupied or empty. The system operates in a variety of lighting conditions and can cope with different vehicle sizes- without giving misleading results if pedestrians are standing in a parking space, for example, or shopping trolleys are left behind.
