Abstract
A device for determining the wheel and axle geometry of motor vehicles in an inspection room using an optical measuring device having at least one optical image pick-up device from at least two different perspectives, having a marking device, which includes a measuring feature arrangement existing or arranged on the wheel, and having an evaluation device. The determining the geometrical wheel and axle data is simplified in that the marking device has at least one reference feature arrangement including at least three reference features per image recording position; that the inspection room is defined between the reference feature arrangement(s) and the base plane of the measuring station; that the position of the reference features in the inspection room is known in the evaluation device; and that the measuring feature arrangement includes at least three measuring features per wheel.
