Abstract

The invention discloses a retinal vessel artery and vein distinguishing method. The method comprises: obtaining a blood vessel extraction image, a fundus image and optic disc center coordinates; extracting a main blood vessel according to the blood vessel extraction image, the fundus image and the optic disc center coordinate; the method comprises the following steps: obtaining a main blood vesselimage, intercepting a main blood vessel based on the main blood vessel image to obtain a plurality of single blood vessel sections, performing pipe diameter measurement on the plurality of single blood vessel sections to obtain the pipe diameter width of each single blood vessel section, and selecting and obtaining a plurality of arteriovenous blood vessel pairs according to the pipe diameter widths. The method is advantaged in that the test effect on the fundus retina color image of the actual scene is excellent, relatively good effects are realized for fundus images of different types, different brands and different levels of image quality, algorithm robustness and universality are relatively strong, and possibility is provided for retina vessel arteriovenous distinguishing and tube diameter measurement algorithm actual scene landing.

Description

technical field [0001] The present disclosure relates to the technical field of computer-aided diagnosis, and in particular to a method, device and equipment for distinguishing retinal vessels from arteries and veins. Background technique [0002] The fundus retinal vessel diameter ratio index is an important reference index for doctors in diagnosing arteriosclerosis. However, when the doctor actually reads the film, he still relies on the visual method to give a rough ratio of the arteriovenous diameter ratio: greater than 1 / 2, greater than 1 / 3 and less than 1 / 2, less than 1 / 3, etc. However, the method of visual inspection has large errors after all, especially for new ophthalmologists or general ophthalmologists, it is inevitable that there will be misjudgments in the process of film reading. Therefore, the accurate measurement of the ratio of the diameter ratio of the main retinal vessels to the artery and vein by the computer is of great help to doctors in the clinical ...
