Abstract

In a single camera single source gaze tracking system, if we can accurately estimate the 3-D coordinates of the iris center and the center of corneal surface curvature, we can reconstruct 3-D gaze direction. A novel method is proposed in this paper, different from other gaze tracking systems, the user calibration in this paper is the calibration of the iris radius, corneal curvature radius and kappa angle. Through the simulation experiments, the feasibility of the algorithm proposed in this paper is analyzed, and the error of the algorithm is relatively small.
