  • Patent number: 11030455
    Abstract: The present disclosure belongs to the field of 3D gaze point recognition and computer vision, and more particularly discloses a pose recognition method, device and system for an object of interest to human eyes, which respectively identifies centers of left and right pupils of a user by using a left eye camera and a right eye camera on an eye tracker to extract information of the user's eyes; maps the obtained centers of the left and right pupils to a left scene camera to obtain a 2D gaze point; extracts bounding boxes of objects in the left scene camera by using target recognition and tracking algorithms, and then determines an object of interest to the user according to a positional relationship between the 2D gaze point and the bounding boxes of the objects; performs 3D reconstruction and pose estimation of the object of interest to the user to obtain a pose of the object of interest in the left scene camera; and converts the pose of the object of interest in the left scene camera to a pose in the world co
