20130162947 | METHOD AND DEVICE FOR DETERMINING THE EYE TORSION - The invention relates to a device for determining eye torsion, comprising a camera and an image processing unit, which is designed to carry out a method for determining eye torsion. In the method, at least two images of an eye are recorded and image data are produced from said images, and at least one characteristic feature of the eye is identified from the image data, for example a blood vessel. Direction histograms of the feature in both images are produced and compared with each other. The angle of the torsion of the eye is determined from the shift of the directions in the direction histograms. | 06-27-2013 |
20130120712 | METHOD AND DEVICE FOR DETERMINING THE EYE POSITION - 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. | 05-16-2013 |
