摘要： 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.

摘要： A camera system and method for controlling same, including capturing images of surroundings of a vehicle for a driver assistance system thereof. The camera system includes a first rolling shutter camera having a first aperture angle, a second rolling shutter camera having a second aperture angle, and control electronics. The first and second cameras are suitable for generating wide-angle and tele camera images, respectively. The first aperture angle is greater than the second aperture angle. The two cameras are designed such that both camera images have an overlap region. The control electronics synchronizes the two cameras. The geometric arrangement of the two cameras with respect to one another, and the position of the overlap region in the wide-angle image and in the tele camera image, are determined by continuous estimation. The stored geometric arrangement and position are taken into consideration during synchronization of the first and second cameras.

摘要： The invention relates to a camera system, and to a method for controlling the camera system, for capturing images of the surroundings of a vehicle for a driver assistance system of the vehicle. The camera system comprises a first rolling shutter camera (1) having a first aperture angle α, a second rolling shutter camera (2) having a second aperture angle β, and control electronics. The first camera (1) is suitable for generating a wide-angle camera image, that is, the first aperture angle α is greater than the second aperture angle β of the second camera (2) which is suitable for generating a tele camera image. The two cameras (1, 2) are designed in such a way that both camera images have an overlap region.
The control electronics is configured to synchronize the two cameras (1, 2).
The geometric arrangement of the two cameras (1, 2) with respect to one another, and the position of the overlap region (10) in the wide-angle image and in the tele camera image, are determined by means of continuous estimation.
The stored geometric arrangement and position are taken into consideration during synchronization of the first camera (1) and the second camera (2) of the camera system.
