Abstract

Measuring pupil size is a noninvasive method for evaluation of autonomic nervous system (ANS) activity because the pupil is exclusively controlled by the autonomic nervous system. To evaluate the activity of ANS, an accurate pupil size calculation method different from those of pupillometer and eye tracker should be suggested. This paper presents a three-dimensional model of eye and pupil and also suggests an accurate estimation method of pupil size from images projected on two-dimensional image plane with distortions.
