Abstract
A method and a device for determining the orientation of at least one rail of a measuring station of a chassis measuring device or a motor vehicle test line. The device has at least one sensing device, the at least one sensing device has at least one camera and at least one illumination unit. The at least one illumination unit illuminates at least one section of the rail using structured or unstructured light and the at least one camera records the light reflected by the rail.

A method for determining at least one of an orientation and a flatness of at least one rail of a measuring station of a chassis measuring device or a motor vehicle test line, the method comprising:
- illuminating, using at least one illumination unit of at least one sensing device having at least one camera and the at least one illumination unit, at least one section of the at least one rail using at least one of structured and unstructured light;
- recording, using the at least one camera, light reflected by the at least one rail;
- and
- carrying out a measurement of a distance between the at least one rail and the at least one sensing device based on the recorded reflected light, wherein, by a first sensing device of the at least one sensing device, a first distance between the first sensing device and a first rail of the at least one rail is measured, and, by a second sensing device of the at least one sensing device, a second distance between the second sensing device and a second rail of the at least one rail is measured, and wherein the first and second sensing devices have a reference system, by which the orientation of the first rail to the second rail is determined based on the first and second distances.

- carrying out a measurement of a distance between the at least one rail and the at least one sensing device based on the recorded reflected light;
- and
- determining, using at least one alignment sensor in the at least one sensing device, the orientation of the at least one sensing device and the orientation of the at least one rail with respect to the Earth's gravitational field.
A method for determining a flatness of at least one rail of a measuring station of a chassis measuring device or a motor vehicle test line, the method comprising:
