US 10,527,519 B2 · High-volume, long-range headlamp aiming

Abstract

A system for aiming a headlamp of a vehicle includes a displaceable aiming surface and an imaging system. The imaging system includes a translatable aim box carrying at least one headlamp imager oriented to capture images of a single headlamp and/or one or more vehicle features adjacent to the single headlamp. At least one fixed imager is oriented to capture one or more images of the displaceable aiming surface. The translatable aim box may be configured to translate between the single headlamp and another headlamp. One or more computing devices are configured to perform methods for headlamp aim correction using the described system. Methods for headlamp aim correction are described.
