Due to an earlier analysis of the interrelation between collisions and advanced driver reaction a significant number of accidents could be avoided through timely threat recognition and appropriate maneuvers for collision avoidance. This may be achieved either by suitable warning to the driver or by automatic support to longitudinal or lateral control of the vehicle. A precondition for the registration of the dangerous situation is the incorporation of appropriate sensors. This leads to an surround sensor vision system accompanied by a matched human machine interface. Many vehicles readily offer ultrasonic reversing aids as add-on systems. Furthermore, long-range radar systems for adaptive cruise control are now coming on the market. New sensor technologies, such as short-range radar and video, which are currently under development, open up a plurality of novel functions thus enhancing driving safety and comfort.

This paper is concerned with the description of a vision system designed for use within future driver assistance systems. The system comprises a high dynamic range CMOS camera, dedicated evaluation hardware based on commercial available PC technology as well as algorithms for the interpretation of video scenes in video real time. The sensor is employed for vehicle environment sensing. Tasks include lane boundary detection, object detection and road sign recognition.
