Disclosed are an algorithm for automatic fundus image reading, and a deep learning architecture for automatic fundus image reading, which are capable of minimizing the amount of data required for learning by training and reading artificial intelligence in a manner similar to that of an ophthalmologist who acquires medical knowledge.

Deep learning architecture system for automatic fundus image reading and automatic fundus image reading method using deep learning architecture system

Disclosed is a coaxial non-mydriatic multispectral fundus camera, including: an illumination unit configured to emit light; a diffusion lens configured to diffuse the light incident from the illumination unit; an illumination lens configured to irradiate the light incident from the diffusion lens at a predetermined emission angle; a mirror configured to reflect the light incident from the illumination lens; a polarizing beam splitter configured to transmit P-polarized light of the light incident from the mirror and reflect S-polarized light thereof; an objective lens configured to image a fundus using the light incident from the polarizing beam splitter and then enlarge a returning image of the fundus; a short-range eyepiece lens configured to reduce or enlarge the image of the fundus enlarged by the objective lens; and an imaging device configured to acquire a fundus photograph from the image of the fundus received from the short-range eyepiece lens.
