Method and apparatus for detecting and following an eye and/or the gaze direction thereof

摘要

An eye-tracking system comprises an illuminator that directs infrared light towards a detection region, a camera configured to generate an image of the detection region and a controller configured to detect a calibration target in the image and to detect or determine changes in the position and/or orientation of the camera relative to the calibration target. The eye-tracking system can be installed in a vehicle.
