Development of pupil reflex measurement system by using the non-invasive measurement method with image recognition

Abstract

This research investigates a non-invasive pupil reflection measurement system. The proposed measurement system includes a pupil area calculation function by using image recognition from the images captured by a camera, and it also has a control function of displaying both light stimulus and gazing point on the monitor. The proposed system can be used with simple instructions. The experimental results show that the characteristic of the pupil reflection obtained by the proposed system is similar to that by the conventional system.
