APPARATUS AND METHOD FOR ROBUST GAZE TRACKING TO CHANGES IN THE EXTERNAL LIGHTING CONDITIONS

摘要

Disclosed are a gaze tracking apparatus resistant to changes in external lighting conditions and a method thereof. The gaze tracking apparatus may include a step of extracting cornea reflected light generated by a lamp from the eye region image of a user, and a step of distinguishing the cornea reflected light generated by a reference lamp used for tracking gaze among the cornea reflected light generated by the lamp by using a virtual gaze tracking region set based on the cornea reflected light generated by the lamp.
