Remote corneal imaging by integrating a 3D face model and an eyeball model

Abstract

In corneal imaging methods, it is essential to use a 3D eyeball model for generating an undistorted image. Thus, the relationship between the eye and eye camera is fixed by using a head-mounted device. Remote corneal imaging has several potential applications such as surveillance systems and driver monitoring. Therefore, we integrated a 3D eyeball model with a 3D face model to facilitate remote corneal imaging. We conducted evaluation experiments and confirmed the feasibility of remote corneal imaging. We showed that the center of the eyeball can be estimated based on face tracking, and thus, corneal imaging can function as continuous remote eye tracking.
