METHOD AND DEVICE FOR SIGHT LINE DETECTION, METHOD AND DEVICE FOR VIDEO DATA PROCESSING, DEVICE AND DATA CARRIER Russian patent published in 2022 - IPC G06K9/00 

FIELD: image processing.

SUBSTANCE: invention relates to the field of image processing, in particular, to a method and device for line of sight detection and video data processing. The effect is achieved by the fact that the detection of the line of sight involves: determining - on the basis of a key characteristic point in the face image - the position of the face corresponding to the image of the face, and the rotational movement of the pupil of the eye, and the rotational movement of the pupil of the eye is a displacement of the center of the pupil in the image of the face relative to the center of the eye apples and backprojecting the rotational movement of the pupil of the eye based on the predetermined projection function and the position of the face into the 3D space where the real face is located to obtain the gaze direction of the real face.

EFFECT: detection of face image and direction of gaze in the video frame, as well as increasing the detection efficiency and accuracy of determining the direction of gaze.
