Abstract:
A device for determining at least one of a wheel geometry and an axle geometry of a motor vehicle in a measuring space, comprising:an optical measuring device including at least two image recording devices, which records from at least two different perspectives a marking device including a plurality of wheel features arranged on a wheel, at least one vehicle body feature and a reference feature array having at least three reference features offset in at least one plane, wherein the recording of the marking device takes place as the motor vehicle travels past; and an evaluation device ascertaining an axis of rotation of a measured wheel by a simultaneous recording of the wheel features and of the at least one vehicle body feature at a plurality of points in time in the measuring space, the evaluation device determining a vertical direction in the measuring space from a position of the reference features in the measuring space, the evaluation device ascertaining a direction of an axis of travel of the motor vehicle based on recording the marking device separately for each wheel from a track of motion of the at least one vehicle body feature, and the evaluation device determining a position of the axis of rotation of the measured wheel with respect to the vertical direction and the direction of the axis of travel.
