An Automatic Calibration Method for Kappa Angle Based on a Binocular Gaze Constraint

An Automatic Calibration Method for Kappa Angle Based on a Binocular Gaze Constraint

Kappa-angle calibration shows its importance in gaze tracking due to the special structure of the eyeball. In a 3D gaze-tracking system, after the optical axis of the eyeball is reconstructed, the kappa angle is needed to convert the optical axis of the eyeball to the real gaze direction. At present...
