Most recent developments in car technology promise that future cars will be equipped with many cameras facing different directions (e.g.: headlights, wing mirrors, break lights etc.). This work investigates the possibility of letting the cameras calibrate and localize themselves relative to each other by tracking one arbitrary and fixed calibration object (e.g.: a traffic sign). Since the fields of view for each camera may not be overlapping, the calibration object serves as logical connection between different views. Under the assumption that the intrinsic camera parameters and the vehicle's speed are known, we suggest a method for computing the extrinsic camera parameters (rotation, translation) for a two-camera system, where one camera is defined as the origin.
