Abstract
A computer-implemented method detects the position of a corneal vertex of an eye from a frontal image of a head and a lateral image of the head. The front and lateral images are calibrated to one another, and the position of the corneal vertex in space is determined from the frontal image and the lateral image with a geometric position determination.
