Throughout the last decade, a large number of electronic driver-assistance systems has been developed in order to improve vehicles' comfort and safety. Up to now, they more or less all rely on odometric data. However in the future, a new form of information is likely to be used: visual sensors, e.g. cameras, can provide additional knowledge on traffic and the vicinity. In this paper an inertially stabilized camera platform for the use with driver assistance systems is presented. A specially designed inertial measurement unit detects the vehicle's rotation and actively stabilizes a pivotable camera with telephoto lens. In order to cope with unknown sensor sensitivities and non-orthogonalities in the sensor mounting, an adaptive biomimetic control algorithm was implemented. The system was evaluated in test drives on motorways at vehicle velocities of up to 130-140 km/h. Camera stabilization removed nearly all detectable correlation of vehicle rotation and image motion thus meaning that the camera was close to perfectly stabilized.
