Patent ID: 8254666

Claim:
A method for determining a wheel geometry and/or axle geometry of motor vehicles using an optical measuring device, comprising the following steps: providing an image recording system that includes at least two image recording devices ( 2 ) for creating digital images; using said image recording system to assign at least two recording points to each other and perform referencing relative to a three-dimensional measurement space while taking into account reference features; registering an object section ( 6 ) including a wheel to be measured from different perspectives; and evaluating a position of wheel features in the three-dimensional measurement space, wherein a 3D group of points is ascertained from the object section registered two-dimensionally by the at least two image recording devices ( 2 ) from different perspectives using image processing methods with correlation of images, wherein the 3D group of points represent a three-dimensional surface of the object section with several individual 3D image points, and wherein the wheel features and the reference features are ascertained therefrom as a point, a 2D function, a 3D function, or a 3D surface, wherein the assignment of the recording points to each other and the referencing are carried out based on reference features ascertained from stationary key structures present anyway in the three-dimensional measurement space, wherein the information provided by the 3D group of points is used directly to extract the wheel features and wherein the amount of data taken into account in the evaluation is reduced by eliminating recording points of uninteresting image regions that were recorded before the 3D group of points is ascertained from the 2D recording points.
