Problems solved by technology

The current ophthalmic diagnosis and treatment mostly use close-up examinations between doctors and patients, the comfort of patients is poor, and the examination results are highly affected by human factors
So far, the technology of fundus image matching, optic nerve measurement, and fundus image stitching based on machine vision technology is still quite imperfect in the medical field.

Abstract

The invention is a method for processing fundus images based on machine vision. The method comprises the following steps of: loading collected fundus images; opening the collected fundus images, matching the fundus images; measuring the fundus images, and splicing the fundus images, wherein the image matching comprises automatic matching and manual matching; carrying out the measurement of the fundus after the completion of matching, cutting the interested region of the matched images, setting as a comparison mode to display two images, and then manually setting a characteristic region in the images, measuring the area of the fundus characteristic region in two images; the fundus image splicing means that a plurality of fundus images are loaded in the eyes of one person to automatically splice, so that a doctor can see the full view of the fundus images of a patient. The invention can realize the functions of real-time analysis, diagnosis, storage and transmission of the fundus images of the patient, thereby assisting the diagnosis of an ophthalmologist to improve the accuracy and the convenience of the diagnosis.

Description

technical field [0001] The invention relates to designing an image processing method, in particular to a fundus image processing method for fundus image matching, optic nerve measurement and fundus image splicing. Background technique [0002] With the development of technology and the growth of the market, the hardware and software of machine vision technology are becoming more and more perfect, and the development of machine vision technology is very rapid. From the 1950s with statistical recognition and analysis of two-dimensional images as the main function, it developed to image shading, texture, motion and imaging geometry. By the 1970s, visual application systems had appeared. Later, with the rapid development of computer technology and the continuous maturity of computer vision theory, intelligent machine vision systems gradually appeared. Digital image processing is widely used in electronics, printing, medicine, food and other manufacturing industries, especially ...
