Abstract

A device for determining the wheel and/or axle geometry of motor vehicles in an inspection room using an optical measuring device having at least two image pick-up devices, which, from at least two different perspectives, record images from a marking device (or optical target), inclusive of at least one wheel feature arranged on each wheel, and including an evaluation device. The marking device further includes an automobile body feature and a reference feature arrangement, including at least three reference features for use in obtaining geometrical wheel and axle data. The inspection room is defined between the reference feature arrangement and the driving surface plane. The position of the reference features in the inspection room is known or stored in the evaluation device. The marking device is detected while the motor vehicle is being driven past. The at least one wheel feature is detected to define a wheel plane in at least three different rotational positions of the wheel, and the at least one automobile body feature is detected at the same time to define the vehicle's motion coordinates. The evaluation device defines at least the wheel and/or axle geometry from the relative…
