Classification: CPC G | IPC G

Claim 31:
32. An apparatus for data processing, the apparatus comprising:
means for providing a 3D model of a person's head,
means for providing a parametric head model having second measurement points;
means for fitting the parametric head model to the 3D model of the person's head;
means for determining first measurement points based on the second measurement points defined on the parametric head model, wherein the first measurement points and the second measurement points have the same spatial coordinates, respectively;
means for determining an accuracy of the fit of the parametric head model to the 3D model of the person's head;
means for setting the first measurement points having the spatial coordinates of the second measurement points as the determined first measurement points if the accuracy of the fit is below a threshold value and setting the first measurement points having adjusted spatial coordinates as the determined first measurement points if the accuracy of the fit is or exceeds the threshold value; and
means for fitting a model of a spectacle frame to the 3D model of the head based on the determined first measurement points.
