REAR-VIEW MULTI-FUNCTIONAL CAMERA SYSTEM
First Claim
1. A rear-view camera system for a vehicle, the rear-view camera system comprising:
- a first camera positioned on a rear side of the vehicle, the first camera producing a first data set that includes image data corresponding to a first field of view;
a second camera positioned on the rear side of the vehicle spaced a horizontal distance from the first camera, the second camera producing a second data set that includes image data corresponding to a second field of view, the first field of view and the second field of view covering a space adjacent the rear side of the vehicle;
an electronic control unit that receives the first data set and the second data set and processes the first data set and the second data set to determine a presence of an object in the space adjacent the rear side of the vehicle, the electronic control unit configured to stitch the first data set and the second data set to produce a panoramic image that corresponds to the space adjacent the rear side of the vehicle; and
a human-machine interface that includes a viewing screen positioned adjacent an operator of the vehicle, the human-machine interface configured to receive the panoramic image and display the panoramic image on the viewing screen.

Abstract
A rear-view camera system for a vehicle. The rear-view camera system includes a first camera positioned on a rear side of the vehicle. The first camera produces a first data set that includes image data corresponding to a first field of view. A second camera is positioned on the rear side of the vehicle spaced a horizontal distance from the first camera. The second camera produces a second data set that includes image data corresponding to a second field of view. The first field of view and the second field of view cover a space adjacent the rear side of the vehicle. An electronic control unit receives the first data set and the second data set and processes the first data set and the second data set to determine the presence of an object in the space adjacent the rear side of the vehicle. The electronic control unit is configured to stitch the first data set and the second data set to produce a panoramic image that corresponds to the space adjacent the rear side of the vehicle. A human-machine interface includes a viewing screen positioned adjacent an operator of the vehicle, and the human-machine interface is configured to receive the panoramic image and display the panoramic image on the viewing screen.

16. A method of detecting an object adjacent a rear side of a vehicle, the method comprising:
-
acquiring, with a first camera, a first image data set that corresponds to a first space positioned adjacent the rear side of the vehicle; acquiring, with a second camera, a second image data set that corresponds to a second space positioned adjacent the rear side of the vehicle; in an electronic processing unit, mapping the first image data set to a first pixel array; mapping the second image data set to a second pixel array; calculating a correspondence between the first pixel array and the second pixel array to produce a third image data set; calculating a driving corridor that corresponds to a predicted path of motion of the vehicle; determining a presence of the object in the third image data set; determining a potential collision between the object and the driving corridor; and calculating a time to collision. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
