Patent number: 8643724Abstract: A multi-camera vision system for a vehicle includes first, second and third image capture devices disposed at respective vehicle portions. The first image capture device field of view overlaps with the third image capture device field of view defining a first overlap zone, and the second image capture device field of view overlaps with the third image capture device field of view defining a second overlap zone. Responsive to processing by an image processor of received image data, a synthesized image is generated without duplication of objects present in the first overlap zone and in the second overlap zone. The synthesized image approximates a view as would be seen by a virtual camera at a single location exterior of the vehicle, and is displayed by a single display screen of a reconfigurable display device that is viewable by a driver of the vehicle when normally operating the vehicle.Type: GrantFiled: March 13, 2013Date of Patent: February 4, 2014Assignee: Magna Electronics Inc.Inventors: Kenneth Schofield, Mark L.

Patent number: 8637801Abstract: A driver assistance system for a vehicle includes an imager and a control having an image processor. The imager is disposed at or proximate to an in-cabin portion of a windshield of a vehicle and has a forward field of view to the exterior of the vehicle through the vehicle windshield. The driver assistance system identifies objects in the forward field of view of the imager via processing of captured image data by the image processor. At least in part responsive to processing of captured image data by the image processor, a determination is made that the vehicle is being operated in an urban environment. Responsive to the determination that the vehicle is being operated in an urban environment, operation of a driver assistance function of the vehicle is inhibited.Type: GrantFiled: July 8, 2013Date of Patent: January 28, 2014Assignee: Magna Electronics Inc.Inventors: Kenneth Schofield, Mark L.
