  • Traffic detection method, device, and system
    Patent number: 10789795
    Abstract: A wireless access device deployed at a traffic station performs short-range wireless communication with a mobile device associated with a target user and entering a signal coverage area of the traffic station. An association between identity information of the target user and the traffic station is detected. An image capture device deployed at the traffic station obtains a facial image of the target user and matches the facial image against facial image samples in a dynamic facial sample library. A gate associated with the traffic station is controlled based on a result of a matching operation performed with the facial image and the facial image samples in the dynamic facial sample library.
