Classification: CPC G | IPC G

Claim 20:
21. A computer-readable non-transitory storage medium comprising instructions that, upon execution by a computer, cause the computer to carry out the following steps:
providing a 3D model of a person's head;
defining second measurement points on a standard head of a parametric head model;
fitting the parametric head model to the 3D model of the person's head;
transferring first measurement points on the 3D model of the person's head based on positions of the second measurement points defined on the parametric head model after the process of fitting the parametric head model to the 3D model of the person's head by projecting the second measurement points onto the 3D model of the head; and
fitting a model of a spectacle frame to the 3D model of the person's head based on the determined first measurement points,
wherein the model of a spectacle frame is a parametric model.
