眼球追踪方法、装置、计算机设备和存储介质
By acquiring the distances between multiple reflection points on the eyeball and the position of the pupil center point, and combining this with three-dimensional shape fitting, the problem of low eye tracking accuracy in existing technologies has been solved, achieving higher precision in tracking eyeball rotation angle and displacement.

AI Technical Summary
Existing eye-tracking technology relies solely on pupil tracking, resulting in low interaction accuracy and an inability to accurately reflect the three-dimensional rotational movements of the eyeball.
By obtaining the reflection distances of at least five reflection points on the eyeball, the three-dimensional center position of the eyeball is determined. Combined with the current three-dimensional position of the pupil center point, the rotation angle of the eyeball is calculated, and a light ranging device such as an infrared camera or a laser ranging device is used to perform three-dimensional shape fitting.
It improves the precision and accuracy of eye tracking, enabling more accurate determination of the eye's rotation angle and displacement.
