Method For Optical Chassis Measurement

A method for optical chassis measurement at a testing station, in which radiation reflected against a surface structure of a vehicle, including at least one wheel and a chassis opening surrounding it, is detected by a measuring device by means of a corresponding sensor system and, through evaluation of position data acquired from the detected radiation, at least the wheel plane and the wheel center point are determined,

• wherein the surface structure of at least one opening of the chassis and of at least the wheel is scanned over its area—or at least along any two lines that intersect both the wheel and the chassis—by means of a laser beam emitted by the measuring device and as characteristic structures, at least two surface profiles from the scanned surface structure are acquired, and at points in which the profile lines intersect, for example, with the wheel rim edge or other rotationally symmetrical contours on the wheel and with the wheel opening of the chassis, the spatial positions of characteristic surface points are determined as position data based on which the chassis data of interest are ascertained.
