Abstract
A stereo camera system for a driver assistance system includes a first camera having a first aperture angle and a second camera having a second aperture angle, wherein the first camera produces a wide-angle camera image, the second camera produces a telephoto camera image, and the two camera images have an area of overlap. The first camera is a rolling shutter camera and the second camera is a global shutter camera. The two cameras' shutters are synchronized with one another in particular manners.
Claims17
A stereo camera system, for a driver assistance system,
- comprising a first camera having a first aperture angle and a second camera having a second aperture angle, the first camera producing a wide-angle camera image and the second camera producing a telephoto camera image, the two camera images having an area of overlap,
- wherein the first camera is a rolling shutter camera and the second camera is a global shutter camera, and wherein the stereo camera system is configured so that the first and second cameras are synchronized with one another.
A method of synchronizing a stereo camera system, for a driver assistance system, wherein the stereo camera system includes a first camera having a first aperture angle and a second camera having a second aperture angle, wherein the first camera is a rolling shutter camera and the second camera is a global shutter camera, and wherein the method comprises:
- with the first camera producing a wide-angle camera image, and with the second camera producing a telephoto camera image, wherein the two camera images have an area of overlap, and
- synchronizing the global shutter camera to a time at which a specific pixel of the rolling shutter camera is exposed in the area of overlap during the producing of the wide-angle camera image.
