Lane Departure Warning Assistant (LDW)
LDW-systems are able to recognise by means of an integrated camera, when a vehicle is about to departure from a driving lane. This camera needs to be calibrated geometrically at the end of the vehicle production line. For the calibration, a geometric pattern needs to be placed in front of the camera at a known position.
Usually, the calibration pattern is printed onto a movable screen, that is placed in front of the vehicle during the wheel or headlamp alignment. The lift-system for the calibration screen is integrated into the VisiCon headlamp aiming rig.
The vehicle is either aligned by a centraliser, or its position is measured with help of VisiCon dPP 3D-sensors.
