A device for determining the wheel and/or axle geometry of motor vehicles in a measuring space, using an optical measuring device having 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, and having an evaluation device, the position of the reference features in the measuring space being known to the evaluation device, the recording of the marking device taking place during the passage of the motor vehicle and the axis of rotation of a measured wheel being ascertained by the 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. In a simplified design, the determination of the wheel and/or axle geometry is made easier by determining the vertical direction in the measuring space from the position of reference features in the measuring space, by ascertaining the direction of the axis of travel of the motor vehicle in the evaluation device on the basis of recording the marking device separately for each wheel from a track of motion of the at least one vehicle body feature, and by determining the position of the axis of rotation of the wheel with respect to the vertical direction and the direction of the axis of travel.
