WIPO Patent Application WO/2020/062523
Kind Code:
A1
Abstract:
A gaze point determination method and apparatus, and an electronic device and a computer storage medium. The method comprises: acquiring a two-dimensional coordinate of an eye feature point of at least one eye on a human face in an image (102), wherein the eye feature point comprises an eyeball center region feature point; acquiring, on the basis of a two-dimensional coordinate of the eyeball center region feature point, a three-dimensional coordinate, in a preset three-dimensional coordinate system, of the corresponding eyeball center region feature point in a three-dimensional human face model corresponding to the human face in the image (104); and obtaining a determination result regarding an eye gaze point position on the human face in the image according to two-dimensional coordinates of feature points, except the eyeball center region feature point, from among the eye feature points, and the three-dimensional coordinate of the eyeball center region feature point in the preset three-dimensional coordinate system (106).
