1. A multi-camera vision system for a vehicle, said multi-camera vision system comprising:

  • a rear-mounted video camera at a rear portion of a vehicle equipped with said multi-camera vision system;

    said rear-mounted video camera having at least a rearward field of view external of the equipped vehicle;

    said rear-mounted video camera operable to capture image data at least rearward of the equipped vehicle during driving of the equipped vehicle;

    a front-mounted video camera at a front portion of the equipped vehicle;

    said front-mounted video camera having at least a forward field of view external of the equipped vehicle;

    said front-mounted video camera operable to capture image data at least forward of the equipped vehicle during driving of the equipped vehicle;

    a first side-mounted video camera at a driver-side side portion of the equipped vehicle;

    said first side-mounted video camera having at least a sideward field of view external of the equipped vehicle;

    said first side-mounted video camera operable to capture image data at least sideward of the equipped vehicle during driving of the equipped vehicle;

    a second side-mounted video camera at a passenger-side side portion of the equipped vehicle;

    said second side-mounted video camera having at least a sideward field of view external of the equipped vehicle;

    said second side-mounted video camera operable to capture image data at least sideward of the equipped vehicle during driving of the equipped vehicle;

    wherein the equipped vehicle is further equipped with at least one non-visual sensor having a field of sensing exterior of the equipped vehicle;

    wherein said at least one non-visual sensor senses sensor data;

    a central data processor disposed in the equipped vehicle;

    wherein image data is provided to said central data processor;

    wherein sensor data is provided to said central data processor;

    wherein, at said central data processor, image data is fused with sensor data and processed in order to detect vehicles that are present external the equipped vehicle;

    wherein processing at said central data processor of captured image data comprises use of an edge detection algorithm;

    wherein said central data processor comprises a digital signal processor operable to process data at a data processioning speed of at least 30 MIPS;

    wherein, via processing at said central data processor of image data and sensor data, a potential hazard present exterior the equipped vehicle is determined to exist; and

    wherein said potential hazard arises from presence of rear-approaching traffic in at least one of (i) a side lane to the equipped vehicle and (ii) a rear lane to the equipped vehicle.
