| 内容記述 | It is generally said that early detection and early training are necessary as eye position abnormality causes stereoscopic vision failure and eye strain. Particularly, strabismus is also a risk factor causing amblyopia, and how to find strabismus at a low age and start treatment can be a major research theme in pediatric ophthalmology. However, the diagnosis of eye position abnormality is difficult, so inspection by qualified persons such as ophthalmologist or vision trainer is required, but this type of qualified person is chronically insufficient. Based on the above, this research aims to develop a simple inspection system that can detect ocular position abnormality such as strabismus and oblique position even in the absence of qualified person. In this study, we attempted a method to detect the presence / absence of inner / outer / upper / lower strabismus or oblique position by tracking the movement of the center position of the pupil, not the conventional method of seeing the movement of the entire eyeball. Here, in order to acquire eyeball information, we use an infrared camera that performs imaging by irradiating infrared light. For estimating the center position of the pupil, a pseudo center of the pupil is obtained by generating a binary image in which the pupil portion is black, using the RGB value, and then obtaining the center of gravity of the black area as the pupil portion. As a result of confirming the performance of this development system by verification experiments, the correct answer rate of the inspection result in this system was about 84%. As a cause of the judgment failure, it was clarified by the experiment that the infrared light reflected on the pupil and the lower eyelid covered with the pupil, and it became clear as a future research subject. | |||||
