Abstract
The invention relates to a method and device for determining eye position, wherein a light pattern is produced on the surface of an eye by means of a light source and an image of the light pattern produced on the eye is recorded by means of an image recording apparatus, wherein points of the transition region between the sclera and the iris of the eye are determined from the image of the light pattern by means of an image processing apparatus. The coordinates of the calculated points are calculated by triangulation or stereovision, and the position of the iris plane or a plane oriented parallel thereto is determined from said coordinates. The limbus of the eye and the center thereof can also be determined in three dimensions.
