ABSTRACT:
A method of determining the spatial relationship of an eye (10) of a person with respect to a camera device (20) which provides images of the eye (10) comprises:a model acquisition phase in which a customized model of the eye (10) is constructed and a reference spatial relationship of the eye model with respect to the camera device (20) is determined using a reference image of the eye (10); anda tracking phase in which position and/or rotation coordinates of the eye (10) are determined by aligning the eye model to a current image of the eye (10).
