Abstract
A vehicular blind spot detection system (700) for alerting a driver of a motor vehicle to an object in the vehicle's blind spot, the system includes a first imaging device (707) used typically used to control vehicle lighting and that works to detect objects substantially forward of the vehicle and a second imaging device (709) typically used with a rear camera display (RCD) for detecting objects substantially rearward of the vehicle. A control unit (711) is coupled to the first imaging device (707) and second imaging device (709) that includes a graphic processing unit (713) for processing images captured by the first imaging device (707) and second imaging device (709) for detecting an optical flow of objects within the images so as to discriminate between vehicles and other objects entering the driver's blind spot.
