METHOD, SYSTEM AND STORAGE MEDIUM FOR EVALUATING EYE MOTION

Abstract: a method, system and storage medium for evaluating the angle of ocular movement are disclosed. the evaluation method includes capturing a first gaze bitmap of the user looking straight ahead at a position in front of the eyes in a near-infrared light band of 700-1200 nm, capturing a second eye gaze bitmap and a third eye gaze bitmap of the user's eye moving to a limit position in the direction(s) to be measured, comparing the first gaze bitmap respectively with the second eye gaze bitmap and the third eye gaze bitmap, and calculating the angle of ocular movement. the eye images are taken in near-infrared light, which effectively differentiates the iris from the pupil so as to accurately identify the pupil edge, and then calculates the angle of ocular movement by comparing different eye gaze bitmaps, and further improves the calculation accuracy of the angle of ocular movement through compensation.
