GAZE TRACKING VIA EYE GAZE MODEL |
| 摘要 |
Examples are disclosed herein that are related to gaze tracking via image data. One example provides, on a gaze tracking system comprising an image sensor, a method of determining a gaze direction, the method comprising acquiring image data via the image sensor, detecting in the image data facial features of a human subject, determining an eye rotation center based upon the facial features using a calibrated face model, determining an estimated position of a center of a lens of an eye from the image data, determining an optical axis based upon the eye rotation center and the estimated position of the center of the lens, determining a visual axis by applying an adjustment to the optical axis, determining the gaze direction based upon the visual axis, and providing an output based upon the gaze direction. |

1. On a gaze tracking system comprising an image sensor, a method of determining a gaze direction, the method comprising:
acquiring image data via the image sensor; detecting in the image data facial features of a human subject; determining an eye rotation center based upon the facial features using a calibrated face model; determining an estimated position of a center of a lens of an eye from the image data; determining an optical axis based upon the eye rotation center and the estimated position of the center of the lens; determining a visual axis by applying an adjustment to the optical axis; determining the gaze direction based upon the visual axis; and providing an output based upon the gaze direction. |
