Abstract
A vehicle headlamp aiming system includes a displaceable aiming surface and an imaging system. The imaging system includes an indexing aim box having at least one imager oriented to capture images of a headlamp and/or one or more vehicle features adjacent to the headlamp and at least one fixed imager oriented to capture one images of the displaceable aiming surface to determine a headlamp cutoff height. The displaceable aiming surface is configured to selectively displace to allow passage of the vehicle. The indexing aim box is configured to translate between the headlamp and another headlamp. One or more computing devices are configured to perform methods for headlamp aim correction using the described system. The methods include providing image inputs from the imaging system and calculating therefrom an aim correction of the headlamps.
