Abstract: A method for is disclosed for rectifying images and/or image points acquired by camera of a camera-based system of a vehicle with a windshield pane. A raw image of a scene is acquired with the camera. Raw image data is selected from the raw image. Intermediate image data is calculated based on the raw image data and camera parameters. The intermediate image data includes an intermediate image or intermediate image points. The intermediate image data resembles an image/image points of the scene obtained by a pinhole camera through the windshield pane. A set of points in space of the scene is calculated, the set of points corresponding to pixels of the intermediate image or to the intermediate image points. The calculation is performed using a parallel shift of the optical path induced by the windshield pane based on windshield pane parameters. Also disclosed is vehicle and a camera-based system therefor.

Abstract: The invention relates to a method for capturing and processing a digital panoramic image. The method involves projecting a panorama (1) onto an image sensor (4) by means of a panoramic objective lens (3) to obtain a raw image (6). Then, a set (7) of N output images (8) is created based on the raw image (6). N is greater than or equal to two and each output image (8) represents a gnomonic projection of the panorama (1) with a given focal length. The output images (8) have a common predetermined resolution, the focal length of the first output image (8.1) has a predetermined focal length value, and the focal length of each other output image (8.2; 8.3) is shorter than that of the previous output image (8.1; 8.2). The invention further relates to a digital panoramic camera system (2), comprising a panoramic objective lens (3), an image sensor (4) and image processing electronics (5). The image processing electronics (5) are adapted to perform the method according to the above description.

Abstract: 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 ?, a second rolling shutter camera (2) having a second aperture angle ?, and control electronics. The first camera (1) is suitable for generating a wide-angle camera image, that is, the first aperture angle ? is greater than the second aperture angle ? 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.
