Abstract:
1. A method for measuring a vehicle wheel with the aid of a measuring system comprising at least one sensor system for recording a contour of the vehicle wheel in a measurement coordinate system, the method comprising the following steps: positioning the vehicle wheel in a measurement position in the coverage range of the senor system, wherein the vehicle wheel is substantially rotationally symmetrical with respect to a measurement object axis, the vehicle wheel axis extending through a bore in a central hub of the vehicle wheel; establishing the position of the vehicle wheel and determining an object coordinate system by means of the central hub of the vehicle wheel which functions as a reference structure positioned at or near the measurement object axis; linking the object coordinate system with the measurement coordinate system; rotating the sensor system around the vehicle wheel for determining contour data selected from the group consisting of surface contour data and wall thickness data of the vehicle wheel; and processing the contour data in an evaluation unit and compensating for an imprecise location of the vehicle wheel in the measurement position by taking account of the position of the object coordinate system in relation to the measurement coordinate system.
