Abstract

The invention provides a retinal blood vessel branch angle calculation method and device and electronic equipment, and the method comprises the steps: obtaining a retinal fundus image, and carrying out the binarization processing of the retinal fundus image, and obtaining a black and white image; based on the black-and-white image, determining an optic disc center point, and based on the black-and-white image, determining two target branch blood vessels of the retina; and based on the optic disc center point and the two target branch blood vessels, obtaining the branch angle of the retinal blood vessels. According to the retinal blood vessel branch angle calculation method and device and the electronic equipment, the blood vessel branch angle of the human eye retina can be accurately calculated.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method, device and electronic equipment for calculating retinal vessel branch angles. Background technique [0002] The fundus camera belongs to the field of medical imaging and is used to obtain retinal fundus images for subsequent processing and observation of the human retina. Since the blood vessels of the fundus are the only blood vessels that can be directly observed through the body surface, the retinal fundus image obtained by the fundus camera can check the state of the optic nerve, retina, choroid and refractive medium of the fundus, that is, determine the state of the human eye. [0003] When determining the state of the human eye, it is generally necessary to calculate the angle between the two main branches in the middle of the retinal blood vessel, that is, the branch angle of the retinal blood vessel. However, there is still a lack of a scheme th...
