Description
Technical Field
The invention belongs to the technical field of security entrance guard identification, and particularly relates to a guest prejudgment analysis method and system based on face identification.
Background
The face recognition technology is widely applied to organs or enterprises and public institutions, face access control equipment is installed in each floor and each room, graded security management is achieved through the face access control equipment, and low security levels cannot enter areas, buildings and rooms with high security levels. However, institutions or enterprises often have visitors to communicate, visit or visit. Because the visitor does not belong to the internal staff and is not convenient to provide the face information in advance, the face access control system judges the visitor personnel as strangers and limits the passage of the visitor. Therefore, the guest prejudgment analysis system based on the face recognition can automatically judge the security level of the visitor and allocate proper passing permission according to the identity and attitude of the internal accompanying person.
The visitor visits for the first time, and generally enters a hall of an organization accompanied by an internal accompanying person. A face recognition device is required to be arranged in a hall, the security level of an internal accompanying person and the body language of the person visiting the visitor are utilized, the human body postures of the visitor and the internal accompanying person are automatically recognized by a face recognition algorithm, the security level of the visitor is automatically judged, then the face information of the visitor is automatically added into a face access control system, and the visitor can smoothly communicate, visit and observe in a unit. The method not only ensures the free passage of the guest, but also can limit the guest from entering a high security level area, and prevents information leakage.
Therefore, it is very necessary to design a new guest prediction analysis method and system based on face recognition.
