DEVICE AND METHOD FOR DISTANCE DETERMINATION AND / OR CENTERING USING CORNEAL REFLEXIONS

摘要

A device including an image capturing device and a measuring device for determining the distance of at least one eye of a user from the image capturing device. The measuring device comprises a lighting device that is arranged at a specified position relative to the image capturing device and is designed to generate at least one specular light reflection, which has a linear portion, on the cornea of the eye of the user. The measuring device also comprises a distance determining device. The image capturing device is designed to capture at least one image of the specular light reflection in the region of the cornea of the at least one eye of the user. The distance determining device is designed to ascertain data relating to the distance between two specified points of the light reflection and the curvature of the at least one linear portion of the light reflection in the captured image; and to ascertain the distance of the eye from the image capturing device using the ascertained data relating to the distance between the two specified points of the light reflection and the curvature of the at least one linear portion of the light reflection. The invention further relates to a method for determining the distance of at least one eye and to a computer program product.
