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.

Claim (Index 1):
A computer-implemented method for detecting a position of a corneal vertex, the method comprising:\n recording a frontal image of a head and a lateral image of the head, calibrating the frontal image and the lateral image to one another, determining a position of a corneal vertex in space from the frontal image and the lateral image with a geometric position determination, the geometric position determination including:\n determining a position of the corneal vertex in space to a first approximation as the point of intersection q of:\n a first view ray, tangential to the cornea, from a lateral camera recording the lateral image, with \n a second view ray, directed onto the pupil, from a frontal camera recording the frontal image, \n \n detecting at least one of a position of a pupil or detecting a position of a reflection point of a flash, producing the flash when recording the frontal image and the lateral image and the position of the corneal vertex in space is determined to the first approximation as a position of the reflection point of the flash on the cornea, and detecting the position of the pupil or detecting the position of the reflection point by performing at least one of:\n extracting a feature, matching a feature, or comparing by machine learning a plurality of data known in advance.
