An image processing type aligner enables proper set-up of one of two optical adjustment elements used to align an adaptive cruise control sensor or the like mounted on a vehicle. One element, such as a laser beam source, is mounted with the sensor on the vehicle; and the other element, such as a mirror, is mounted on a stand. A carrier on the stand positions two optical targets of the aligner at transversely spaced apart locations. The stand is positioned between the vehicle and the aligner and manipulated until the aligner indicates that the axis of the adjustment element on the stand is aligned relative to the thrust line of the vehicle. A beam of light is transmitted between the two adjustment elements, and the technician adjusts the sensor until the beam position indicates a desired alignment of the sensor relative to the thrust line.
