Non-invasive eye tracking technology based on corneal reflex
For the deficiencies that existing eye tracking devices are complex,have too many restrictions on the position,need to wear special equipment.A novel method of eye tracking technology using the five near-infrared light as the source of corneal reflex was put forward.This method did not need any wear...

| description | For the deficiencies that existing eye tracking devices are complex,have too many restrictions on the position,need to wear special equipment.A novel method of eye tracking technology using the five near-infrared light as the source of corneal reflex was put forward.This method did not need any wearing equipment,and could adapt to the natural head movement,the algorithm designed calculates the position of sight in high accuracy.A novel method of pupil edge fitting was put forward:fitted circularly and removed false points to get accurate position of pupil center,improved mapping accuracy.Used the GrayScale of image to initialize eye position quickly and accurately.Using the theory of cross-ratio invariance to make coordinate mapping,finally calculated the attention coordinate accurately. |
