The invention relates to a method and an image processing system for determining parameters of a camera. According to the method, an image of a surrounding area is captured by the camera, and camera parameters are initially determined. Furthermore, a three-dimensional geometric description of visual features (02) of the surrounding area is provided. A feature detector is used on the captured image in order to extract visual features (01). The initially determined camera parameters are applied to the three-dimensional geometric description of the visual features (02) of the surrounding area in order to display said visual features on a feature image. According to the invention, a quantity of the visual features (01) extracted from the image is compared with a quantity of the visual features (02) in the feature image in order to determine a degree of concordance between the two quantities. The camera parameters are changed repeatedly in order to determine additional feature images for which the degree of concordance is determined until said degree exceeds a threshold. |
