US 10,853,967 B2 · Method and apparatus for determining pupil position

Abstract

The present disclosure discloses a method and apparatus for determining a pupil position. The method includes that: at least one first parameter of a pupil in an image, an initial edge region of the pupil and at least one second parameter of at least one light spot in the image are acquired; the initial edge region is corrected according to the at least one first parameter and the at least one second parameter to obtain a first edge region; a pupil edge region is determined according to an edge section in the first edge region, and the edge section is a region formed by a point set meeting a first preset condition in the first edge region; and fitting processing is performed on the pupil edge region to obtain a position of the pupil.
