BACKGROUND

Face recognition is a new biometric recognition technology that has emerged in recent years with the rapid development of computer vision, pattern recognition, neural networks, artificial intelligence, and other technologies. Face recognition implements identification mainly based on geometric information, such as the position, shape and face contour of each face organ provided by face feature points. Therefore, in a face recognition process, the positioning of the face feature points is very important. At present, the positioning of the face feature points can achieve high precision by means of deep learning.

SUMMARY

The present disclosure relates to, but not limited to, the technical field of computers, and in particular, to gaze point determination methods and apparatuses, electronic devices, and computer storage media.

Embodiments of the present disclosure provide a technical solution for gaze point determination.

According to one aspect of embodiments of the present disclosure, a gaze point determination method is provided, including:

obtaining two-dimensional coordinates of eye feature points of at least one eye of a face in an image, where the eye feature points include an eyeball center area feature point;

obtaining, in a preset three-dimensional coordinate system, a 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 an 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.

According to another aspect of the embodiments of the present disclosure, a gaze point determination apparatus is provided, including:

an obtaining unit configured to obtain two-dimensional coordinates of eye feature points of at least one eye of a face in an image, where the eye feature points include an eyeball center area feature point; and obtain, in a 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

a determination unit configured to obtain a determination result for the 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.
