Patent ID: 7860295

Claim:
A computer-implemented method for determining the spatial position of wheel rim to a measuring unit, that includes at least one camera, wherein the wheel rim lies in the viewing field of the camera, the method comprising: making available of a model that describes a model body of a localizable wheel rim geometry detail as well as the spatial position of the model body to the measuring unit through model parameters, capturing of a picture of the wheel rim geometry detail of the wheel rim with the camera, fitting, by the computer, of the picture of the model body resulting from the model parameters to the picture of the rim geometry detail through changing the model parameters of the model, and tracking, by the computer, the changes of the model parameters of the model upon the fitting, wherein the data related to the position of the model body of the wheel rim geometry detail reflect the spatial position of the wheel rim geometry detail and, thereby, of the wheel rim itself, when the image resulting from the model parameters of the model body of the wheel rim geometry detail matches to the captured picture of the wheel rim geometry detail within the asserted tolerance limits.
