The face information is transmitted to the information storage device 4 of the entrance guard terminal provided with face recognition of the door allowing the user corresponding to the face information to enter through the management server 7. Therefore, an operator can collect face information pictures of users at an access control terminal with any face recognition in the access control system, and the added user individuals can enter the door through the rules of the user individuals, and the face information adding work is convenient and simple.
Specifically, when face information is added in the face data acquisition, a face picture to be added is acquired by the video acquisition device 1, and then whether the acquired face picture contains a face or not is detected by the face recognition device 2, and whether the face picture is from a living body or not is detected. When the picture is a human face and comes from a living body, the human face characteristics of the picture are acquired through the human face recognition device 2, the human face characteristics are stored in the information storage device 4 of the entrance guard terminal with the human face recognition, then the human face characteristics are transmitted to the management server 7 through the communication device 6, the human face information temporarily stored in the information storage device 4 is deleted, the human face information distributed by the management server 7 is received through the communication device 6 to be synchronously replaced, and the human face information adding work is completed.
The human-computer interaction device 5 further comprises a loudspeaker connected with the face recognition device 2 and used for prompting the user when the face information comparison is successful and giving an alarm to the user when the face information comparison is failed. The result that whether the comparison of the face information is successful or not can be conveniently received by the user through the loudspeaker, and the method is more convenient to display by adopting characters.
When the human face images are compared successfully, the door control device 3 unlocks the door, and the human-computer interaction device 5 can also provide a prompt that the door is in an open state for a user entering the door, namely, the user makes a sound through a loudspeaker of the human-computer interaction device 5. When the face features of the picture cannot be matched with any face in the face information, it is indicated that the face is not the user added with the registration in advance, and the human-computer interaction device 5 also sends an alarm prompt that the user does not exist.
Preferably, as shown in fig. 2 and 4, the information storage device 4 is connected to the door control device 3, and the information storage device 4 synchronizes the door opening records of the door control device 3 to the management server 7 through the communication device 6; the use condition of the access control is traced through the door opening record so as to check which people enter the door once in a certain time period (such as the latest time period), and particularly, when abnormal conditions such as data loss and property loss occur, clues are provided for checking the above conditions.
The information storage device 4 is connected to the face recognition device 2, and the information storage device 4 synchronizes the face information comparison result of the face recognition device 2 to the management server 7 through the communication device 6 and stores the face information comparison result. The method and the device are used for recording all records, particularly records of unsuccessful face image comparison, from the beginning of face recognition to the opening of the door, and are convenient for tracing the condition of contacting the access control terminal within a certain period of time.
