Blind spot detection system and method using preexisting vehicular imaging devices

A blind spot detection system for monitoring activity along a vehicular border, the system comprising:

• at least one monitoring device each comprising:
• a first image sensor for capturing images along and in the vicinity of a first field of view;
• a second image sensor for capturing images along and in the vicinity of a second field of view;
• a control unit coupled to the first image sensor and second image sensor for processing the captured images and detecting moving objects in the captured images and, when a moving object is detected, causing a signal to be transmitted to alert a driver indicating that motion has been detected in the vehicle's blind spot;
• and
• wherein the control unit comprises a graphic processing unit coupled to the image sensor for processing images captured by the image sensor for detecting an optical flow of objects within the images so as to discriminate between moving objects and non-moving objects in a vehicles' blind spot.
