Abstract

A new method to recover and display 3D fundus pattern on the inner bottom surface of eyeball from stereo fundus image pair is developed. For the fundus stereo images, a simple stereo technique does not work, because the fundus is observed through eye lens and a contact wideangle enlarging lens. In this method, utilizing the fact that fundus forms a part of sphere, we identify their optical parameters and correct the skews of the linesofsight. Then, we obtain 3D images of the fundus by backprojecting the stereo images.
