Abstract

Optical chassis measurement of motor vehicles is carried out by a measuring arrangement equipped with at least one measuring device, in which one or more image capturing devices associated with one another in terms of their position and location record the surface geometry of a vehicle or measurement points arranged on the vehicle, carry out a referencing and/or orientation of the at least one measuring device in relation to the measuring station with reference features that are arranged at particular measuring station coordinates in the measuring station and, based on orientation data and/or association data obtained and based on measurement data obtained during execution of the axle measurement, an evaluation is carried out in an evaluation unit in order to ascertain chassis data. A precise measurement is achieved in that the measuring station coordinates of the reference features are measured once or at chronological intervals by a preset test feature arrangement in the measuring station in that the at least one measuring device sequentially performs an image capture of the test feature arrangement from at least two different points of view, with the reference features to be mea…
