Abstract
A method for accurately aiming vehicle headlamps, with apparatus for practicing the method. A vision system, including a digital camera, is positioned in front of a headlamp, in communication with a control device. The control device employs pattern recognition to identify the optical axis indicia within the headlamp, and based on the identified location of that indicia, the control system accurately aligns a beamsetter with the optical axis of the headlamp.
