Abstract
Abstract A vehicle monitoring system including a camera mounted on top of the vehicle reflector in operative relation to the camera. The camera and the conical reflector provide a 360° field of view image around the vehicle. A controller is also included is adapted to detect objects within the field of view image, and determine a reference angle between the vehicle and a detected object. The controller also generates a distance value between the vehicle and the detected object as a function of a lane (w) and a reference angle (q). In one embodiment, the system includes an overhead-view display system including a reference vehicle indicator representative vehicle within the environment and an indicator element adapted to display the detected object with respect to the vehicle indicator as a function of the distance value.
