1. A method for tracking eye gaze, comprising:
acquiring original images acquired by a plurality of image acquisition devices, splicing the acquired plurality of original images into one spliced image, and determining a responsible region of each image acquisition device in the spliced image;
performing preliminary face locating on the spliced image, and determining one or more original images corresponding to a preliminarily located face position according to the preliminarily located face position and the responsible region of each image acquisition device in the spliced image; and
performing secondary face locating on the one or more determined original images to obtain face pose information and a positional relation of a pupil with respect to a human eye, and calculating coordinates of a gaze point of the human eye according to the obtained face pose information and the positional relation of the pupil with respect to the human eye.
