[0002] With the advancement of technology, access control machines have evolved from traditional unlocking methods such as entering passwords and swiping cards to face recognition. Access control machines with face recognition function collect facial features of the user to be authenticated, and compare the collected face image with the stored face database data to unlock the door. However, since common cameras are installed above the screen and at a high position, when outsiders look down at the screen or wear hats, it is impossible to accurately obtain the outsiders' facial information, which poses a safety hazard.
