Abstract

The invention provides a glaucoma image recognition method, glaucoma image recognition equipment and a screening system. The glaucoma image recognition method comprises the following steps: acquiringan eye ground image; Extracting a local image from the fundus image, wherein the local image comprises an optic disc and a fundus background; Obtaining an optic disc image and an optic cup image according to the fundus image or the local image; Obtaining a disc edge image according to the visual disc image and the visual cup image; And judging whether the fundus image is a glaucoma image accordingto the disc edge image, the local image and the fundus image.

Description

technical field [0001] The invention relates to the field of eye detection equipment, in particular to a glaucoma image recognition method, equipment and screening system. Background technique [0002] Glaucoma is an irreversible blinding fundus disease. In screening or clinical diagnosis, doctors can judge whether the examinee may suffer from glaucoma by observing fundus images, so as to make recommendations on whether further examination or medical treatment is required. [0003] In clinical diagnosis, ophthalmologists can make judgments by observing the conditions of the optic cup and optic disc in the fundus map. For example, if the optic cup is too large, resulting in an excessively large proportion of the optic cup and optic disc, the examinee is likely to suffer from glaucoma. The cup-to-disk ratio is generally the vertical diameter ratio of the optic cup and optic disc. [0004] However, ophthalmologists estimate the cup-to-disk ratio or the shape of the disc edge w...
