Abstract
A method for analyzing a stereoscopic image of a fundus to detect and analyze an optic disk part on the basis of the stereoscopic image of the fundus, which can provide highly reliable results of analysis even if the fundus is inclined. The method includes: a first step of designating a disk line in the stereoscopic image of the fundus; a second step of determining a lowest point in a disk region which is determined by the designated disk line; a third step of determining a cross section of the disk region at each predetermined angle centering on the lowest point; a fourth step of determining highest points at both ends of a line of longitude on each cross section of the disk region; a fifth step of setting as a cup point a level which is lower from the highest points by a predetermined depth; and a sixth step of forming a cup rim by consecutively connecting the cup points in the cross sections of the disk region determined in the fifth step.
