Specifically, the preferred eye region in this embodiment is the pupil of the scanning subject. According to the image of the scanned object, the position of the pupil in the image is determined, and the specific identification method can be used for identification through a pre-constructed deep learning model. The embodiment does not specifically limit the specific identification method, and only needs to be able to complete target identification. After the pupil position image is acquired, the position of the display device is determined in the image of the scanning object according to the image of the scanning object acquired by the camera, and the relative distance between the eye part and the display device is determined according to the position of the display device and the position of the pupil in the image of the scanning object.
