Patent ID: 7380344

Claim:
A device for determining at least one of a wheel geometry and an axle geometry of a motor vehicle in an inspection room, comprising: an optical measuring apparatus having at least one image-taking device for recording a marking device including at least one body feature and one reference feature system; an evaluating device, positions of reference features in the inspection room being known in the evaluating device, and the recording of the marking device taking place during travel of the motor vehicle, wherein: the image-taking device is connected via a swivel joint to a wheel rim of a wheel that is to be measured, the image-taking device follows a rotational motion of the wheel, an optical axis of the image-taking device is always aligned substantially perpendicular to a roadway plane, an axis of rotation of the swivel joint is aligned in all wheel positions substantially parallel to the roadway plane, the reference feature system is situated substantially in the roadway plane in a field of view of the image-taking device, the at least one body feature is always situated in the field of view and follows a movement of the motor vehicle, and a position of at least one of an axis of rotation of the wheel and a plane of rotation of the wheel is able to be determined on the basis of the position of a wheel feature to be ascertained.
