Abstract
A fundus measuring apparatus which measures a three-dimensional configuration of a fundus on the basis of stereoscopic images of the fundus. With respect to a left image and a right image of inputted stereoscopic images of the fundus, integration data is obtained by integrating density information concerning at least one direction of its vertical direction and horizontal direction. Parallax information is measured on the basis of differential data obtained-by further differentiating the integral data. The height of each portion of the fundus is determined from left and right images extracted from the stereoscopic images of the fundus on the basis of this parallax information, so as to generate a three-dimensional configuration of the fundus.
