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

    wherein said rear backup camera comprises a CMOS imaging array;

    said rear backup camera having a field of view at least rearward of the equipped vehicle;

    wherein the field of view of said rear backup camera encompasses at least a portion of a vehicle bumper of the equipped vehicle;

    said rear backup camera captures video image data at least rearward of the equipped vehicle during a rearward maneuver of the equipped vehicle;

    a forward viewing camera disposed at a windshield of the equipped vehicle and viewing through the windshield forward of the equipped vehicle;

    said forward viewing camera captures video image data at least forward of the equipped vehicle;

    a central data processor disposed in the equipped vehicle;

    wherein image data captured by said forward viewing camera is provided to said central data processor and image data captured by said rear backup camera is provided to said central data processor;

    wherein captured image data provided to said central data processor is processed at said central data processor in order to detect objects that are within at least one selected from the group consisting of (i) the field of view of said forward viewing camera and (ii) the field of view of said rear backup camera;

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

    wherein the equipped vehicle is further equipped with at least one radar sensor;

    wherein said at least one radar sensor captures radar data in a region external of the equipped vehicle;

    wherein captured radar data is provided to said central data processor;

    wherein, via processing at said central data processor of at least one of provided captured image data and provided captured radar data, a potential hazard is determined to exist;

    a display device comprising a video screen that displays video images for viewing by a driver of the equipped vehicle during the rearward maneuver of the equipped vehicle, wherein image data captured by said rear backup camera is processed at said central data processor to generate video images for display on said video screen; and
