Patent ID: 8522609

Claim:
A method for wheel suspension alignment, the method comprising: recording at least three geometrical details of one wheel, respectively, of a vehicle standing in an initial position using each of four measuring heads of a wheel suspension alignment system, the wheel suspension alignment system having the four measuring heads situated in a known position with respect to one another, of which each has a monocular picture recording device; carrying out a relative motion between the vehicle and the measuring heads from the initial position into at least one further position, the relative position of the measuring heads to one another being known; recording at least three geometrical details of one wheel, respectively, of the vehicle standing in the further position using each of the four measuring heads; carrying out local 3D reconstructions for determining translation vectors, rotation vectors and wheel rotational angles between the at least two positions, and of wheel rotational centers and wheel rotational axes of the wheels from the recorded geometrical details; determining a global scale for the measuring heads by scaling the translation vectors of the wheels, so that the translation vectors have the same length; and determining at least one of: a camber, a single toe, or a total toe of the vehicle.
