Eyeball movement function quantitative evaluation system based on eye tracker

Abstract

The invention relates to an eyeball movement function quantitative evaluation system based on an eye tracker, which can realize automatic quantitative evaluation of three eye functions of watching, glancing and smooth tracking, and provides support for eye disease diagnosis and eye rehabilitation effect evaluation. The system comprises an eye tracker, an evaluation interface generation module, a data processing module, a motion function evaluation module and an evaluation result display interface, the obtained eye motion data is processed through a computer, eye motion data characteristics are calculated, eye motion function quantitative rating indexes are designed, a quantitative rating result is automatically given, and the evaluation result is displayed. Therefore, the diagnosis result is more accurate, visual and convenient, the workload of a doctor is reduced, more accurate eye movement diagnosis information is provided for the doctor, the doctor is helped to know the eye movement function state of a patient, and better diagnosis and treatment are facilitated. The system starts from clinical requirements of the ophthalmology department, automatic quantitative evaluation and grading of the eye movement function are achieved, reference is provided for eye disease diagnosis and eye rehabilitation effect evaluation, and the system has important significance.

Description

technical field [0001] The invention relates to the field of eye movement function evaluation, in particular to an eye movement function quantitative evaluation system based on an eye tracker. Background technique [0002] According to a survey in my country, among the five types of disabilities, the proportion of visually impaired children has reached 5%. Among the newly added disabilities every year, the number of visually impaired children increases by about 16,000, of which eye movement dysfunction accounts for a large part, some of which are Recovery can be done surgically or non-surgically, so it’s important to identify problems early and treat them accordingly. However, most of the eye movement disorders are now diagnosed by doctors, so it depends on the experience of doctors, and there is a lot of subjectivity. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, the present invention provides an eye movement function quantitative evalu...
