Easy and Flexible Calibration Approach for Deflectometry-based VR Eye-Tracking systems

Abstract

We present an easy and flexible calibration approach for small field of view Deflectometry systems to be used in VR headsets. Our method replaces all required calibration targets and mirrors with a small (phone) screen to perform intrinsic and extrinsic camera calibration as well as extrinsic calibration of the whole setup.
