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

  • at least three image capture devices disposed at a vehicle equipped with said multi-camera vision system;

    said at least three image capture devices comprising a first image capture device disposed at a driver-side portion of the equipped vehicle at a first location;

    said at least three image capture devices comprising a second image capture device disposed at a passenger-side portion of the equipped vehicle at a second location;

    said at least three image capture devices comprising a third image capture device disposed at a rear portion of the equipped vehicle at a third location;

    wherein said first image capture device has a first field of view exterior of the equipped vehicle;

    wherein said second image capture device has a second field of view exterior of the equipped vehicle;

    wherein said third image capture device has a third field of view exterior of the equipped vehicle;

    wherein said first field of view of said first image capture device overlaps with said third field of view of said third image capture device defining a first overlap zone;

    wherein said second field of view of said second image capture device overlaps with said third field of view of said third image capture device defining a second overlap zone;

    wherein said first image capture device captures first image data;

    wherein said second image capture device captures second image data;

    wherein said third image capture device captures third image data;

    an image processor;

    wherein first image data captured by said first image capture device is received at said image processor;

    wherein second image data captured by said second image capture device is received at said image processor;

    wherein third image data captured by said third image capture device is received at said image processor;

    wherein, responsive to processing by said image processor of received image data, a synthesized image is generated without duplication of objects present in said first overlap zone and in said second overlap zone and wherein said synthesized image approximates a view as would be seen by a virtual camera at a single location exterior of the equipped vehicle;

    wherein said synthesized image is displayed by a single display screen of a display device that is viewable by a driver of the equipped vehicle when normally operating the equipped vehicle;

    wherein a trailer is attached at the rear of the equipped vehicle; and

    wherein said synthesized image assists the driver of the equipped vehicle in executing a maneuver of the equipped vehicle with the trailer attached thereto.
