Embodiment Construction
[0020] The present invention is further described below in conjunction with embodiment.
[0021] In this embodiment, images are collected when the distance between the user's face and the camera is 0.5 meters and 1 meter respectively, the facial contour and eye contour of the collected image are obtained by the black and white color tolerance method, and the facial contour is calculated using mathematical methods and the area of the eye contour and the offset value based on the center line of the entire picture; store the collected and calculated data into the standard database; switch each group of gratings to collect the best video grating occlusion angle of the above two sampling distances of different groups of gratings and offset; collect the image of the face of the current user when using it, obtain the facial contour and eye contour of the collected image through the black and white color tolerance method, and use mathematical methods to calculate the area of the fa...
