Patent ID: 7194378

Claim:
A method for measuring a workpiece, the method comprising the steps of: measuring measurement points on the surface of said workpiece utilizing a measuring apparatus to obtain measured measurement points; evaluating said measured measurement points so as to map a pregiven desired geometry and an actual geometry defined by said measured measurement points one upon the other with a fitting method; providing transformation parameters (a, λ, δ i ) for said fitting method; utilizing said transformation parameters (a, λ, δ i ) to provide a defined transformation of one of said desired geometry and said actual geometry with respect to a targeted geometric change of form of one of said desired geometry and said actual geometry with said defined transformation being achieved without scalar dimensional changes and not being limited to a scaling of one of said desired geometry and said actual geometry; determining deviations between the actually measured measurement points and said pregiven desired geometry; and, providing an output representing the determined deviations.
