Abstract
To monitor both the surrounding of a vehicle and a place distant therefrom, there is mounted on the vehicle a twin-camera (23) composed of cameras (23L, 23R) forming a pair. To properly set the postures of the cameras (23L, 23R), their tilts, pans and twists around the optical axes are adjusted using, as indexes, the lengths of the portions, as captured by the cameras (23L, 23R), of the vehicle center line (BCL), the lengths of the portions, as captured by the cameras (23L, 23R), of the vehicle rear-end line (BEL), and the areas of the blind zones (S) in the capturing directions.
