Abstract

This paper suggests a new method to compensate perspective error in measuring real size of pupil of pupillography for pupil light response. To get real size of pupil, the distance between cornea and camera should be calculated. The glints on the eye of the image were used to estimate the distance. The suggested method was validated using telecentric lens.
