摘要
A method and system are provided for locating the center of the entrance pupil of an eye after the pupil thereof has been dilated. A first image of an eye is formed prior to pupil dilation. The center of the undilated pupil is referenced to a reference image of an anatomical landmark of the eye that appears in the first image. A second image of the eye is then formed when the pupil is dilated. When the reference image is positioned on an image of the anatomical landmark appearing in the second image, the center of the undilated pupil referenced to the reference image defines the center of the entrance pupil of the eye.
