EYE MOVEMENT MEASUREMENT DEVICE, EYE MOVEMENT MEASUREMENT METHOD, AND EYE MOVEMENT MEASUREMENT PROGRAM

摘要

This eye movement measurement device is provided with: an acquisition unit for acquiring an eye image by imaging an eye of a subject; a feature point extraction unit for extracting feature points within the white part of the eye included in the eye image acquired by the acquisition unit; a candidate region generation unit for generating, for each feature point extracted by the feature point extraction unit, a template candidate region which is a region including a pixel of the feature point in the eye image; a selection unit for selecting, as a template region, a template candidate region including more feature points from multiple template candidate regions generated by the candidate region generation unit; and a measurement unit for measuring the three-dimensional movement of the eye of the subject including at least the angle of rotation of the eye by tracking the movement of the eye image acquired by the acquisition unit using the template region selected by the selection unit.
