Abstract
A vehicular imaging system includes an imaging device that is part of an exterior rearview mirror assembly and having a field of view rearward and/or sideward of the vehicle. A control processes captured image data utilizing edge detection. Responsive at least in part to the processing, the control determines objects of interest present in the field of view of the imaging device. Objects of interest determined to be present in the field of view include (i) a vehicle that is rearward and/or sideward of the vehicle, (ii) a headlight of a vehicle that is rearward and/or sideward of the vehicle, (iii) a bicycle that is rearward and/or sideward of the vehicle, and/or (iv) a bicycle rider that is rearward and/or sideward of the vehicle. Responsive at least in part to the processing of captured image data, a driver of the vehicle is alerted to a hazardous condition.
