Abstract

A method for wheel suspension alignment includes: providing four measuring heads each having a monocular picture recording device; recording at least three geometrical details of one wheel, respectively, of a vehicle in an initial position, using each of the four measuring heads; carrying out relative motion between the vehicle and the measuring heads from the initial position into at least one further position; recording at least three geometrical details of one wheel, respectively, of the vehicle 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 wheel rotational centers and wheel rotational axes from the recorded geometrical details; determining a global scale for the measuring heads by scaling the translation vectors to have the same length; and determining camber, single toe and/or total toe of the vehicle.
