Abstract

Provided are an eye tracking method and apparatus for anterior segment OCTA, a device, and a storage medium. The eye tracking method for anterior segment OCTA includes: acquiring two consecutive frames of pupil images; separately performing contour extraction on the two frames of pupil images to obtain two corresponding pupil contours; determining whether the two pupil contours are similar to a reference contour, and in response to the two pupil contours being similar to the reference contour, calculating a central position offset of one of the two pupil contours with respect to the other pupil contour.
