Abstract
The invention relates to a method for determining the wheel geometry and/or axle geometry of motor vehicles by means of an optical measuring apparatus. According to said method, at least two recording points are assigned to each other and are referenced in relation to the measuring space with the aid of an image recording system, optionally taking into account reference characteristics and vehicle body characteristics, an object segment (6) comprising the wheel (5) that is to be measured is detected from different perspectives, and the position of wheel characteristics in the measuring space is evaluated during the measurement. In order to create an advantageous procedure regarding the operation and the accuracy of the measurement, a plurality of individual 3D pixels representing the three-dimensional surface of the object segment that is detected by the at least two image recording devices (2) are determined from the object segment using image processing methods by correlating images, and the wheel characteristics and/or reference characteristics and/or vehicle body characteristics are obtained therefrom.
