In a method for calibrating an image capture device that is mounted on a motor vehicle and able to successively capture images of a road area located in front of the vehicle, at least two image objects which correspond to line segments which are straight and substantially parallel to each other in world coordinates are detected in a captured image. With the aid of the image objects, the position of a vanishing point in the captured image is estimated and tracked by a tracking method. In the process, an error is calculated for the position of the vanishing point. As soon as the calculated error decreases to less than a predetermined threshold value, the image capture device is calibrated with reference to the position of the vanishing point associated with the error. |
