Abstract
A method and a device are provided for the optical axle alignment of wheels of a motor vehicle. At the wheels that are to be aligned, targets are mounted, having optically recordable marks, the targets being recordable by measuring units that have stereo camera devices. In a referencing process, using a referencing device that is integrated into the measuring units, a measuring position reference system is established for the measuring units. In a calibration process, in which a local 3D coordinate system is established using at least three marks of the target, the determination of a reference plane is carried out, using a significant mark of the target. Finally, using the reference plane, a vehicle longitudinal center plane is ascertained, while taking into account the measuring location reference system. In a subsequent measuring process, an image is recorded of at least three indeterminate marks taken during the calibration process, and their spatial position is ascertained in the local 3D coordinate system by the evaluation unit.
