specific Embodiment approach

[0028] In this embodiment, a specific implementation of a pre-processing method for quantitative analysis of fundus images is as follows:

[0029] Step S101: Obtain a fundus image to be processed. The following methods can be adopted: obtain the fundus image uploaded locally, or obtain the fundus image uploaded by the remote fundus image collection terminal, or obtain the fundus image from the server, specifically: collect the fundus image of the subject through the fundus camera, and then transfer the corresponding The fundus image of the subject can be uploaded to the storage device for processing, or the fundus image of the subject can be directly input, or the fundus image of different subjects can be obtained through the cloud. There are various ways to obtain the fundus image without any restrictions .

[0030] After the fundus image to be processed is acquired, step S102 is performed: performing optic disc positioning on the fundus image to be processed. The following...

Abstract

The invention relates to the field of fundus image processing, in particular to a pre-processing method for fundus image quantitative analysis and storage equipment. The pre-processing method for fundus image quantitative analysis comprises the following steps: acquiring a fundus image to be processed; carrying out optic disc positioning on the fundus image to be processed; carrying out macular fovea centralis positioning on the fundus image to be processed; and calculating quantification parameters of the temporal side edge of the optic disc and the macular fovea. Through the method, the obtained data is converted from an absolute representation mode to a relative representation mode, and through normalization processing, meaningful and comparable quantitative analysis data between people, between different people and even between inspection results of different instruments is formed. And meaningful and comparable quantitative indexes can be formed for fundus images from different sources.

Description

technical field [0001] The invention relates to the field of fundus image processing, in particular to a pre-processing method and storage device for quantitative analysis of fundus images. Background technique [0002] Chronic diseases such as diabetes and hypertension have become serious social problems that endanger the health of the general public and affect the quality of life. How to find a suitable way to manage one's own health status, so as to realize the prevention, monitoring and treatment of diseases is an inevitable requirement of the development of today's society. The fundus is the only non-traumatic part of the human body where arteries, veins and capillaries can be directly observed. A large number of studies and clinical practice have shown that retinopathy, changes in retinal blood vessels, and the condition and changes of the optic nerve head reflect to a certain extent People's health and status of atherosclerotic diseases caused by diabetic retinopathy...
