[0026] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0027] Such as figure 1 The present invention requires dual cameras 101 and an infrared light source 102. The camera is located directly above the center of the display 112 to capture face images in real time. The resolution of the cameras is 640×480, the focal length is 10mm, and they are placed side by side on the top of the display. The distance between the two camera lenses is about 5cm. The distance between the center of the dual camera and the bottom of the display is 26cm. Infrared light with a wavelength of 850nm is selected as an auxiliary light source and placed in front of the display screen to illuminate the face.
[0028] Such as figure 2 , The specific implementation steps of the gaze tracking algorithm are as follows:
[0029] Step 1: Focus on the calibrated point 110 and extract the eye movement feature information
[0030] Step 2:...
