Abstract:
A gaze point determination method and apparatus, an electronic device, and a computer storage medium are provided. The method includes: obtaining two-dimensional coordinates of eye feature points of at least one eye of a face in an image, the eye feature points including an eyeball center area feature point; obtaining, in the preset three-dimensional coordinate system, three-dimensional coordinate of a corresponding eyeball center area feature point in a three-dimensional face model corresponding to the face in the image based on the obtained two-dimensional coordinate of the eyeball center area feature point; and obtaining a determination result for a position of a gaze point of the eye of the face in the image according to two-dimensional coordinates of feature points other than the eyeball center area feature point in the eye feature points and the three-dimensional coordinate of the eyeball center area feature point in the preset three-dimensional coordinate system.
