Research And Implementation Of Face Recognition Access Control System Based On Wireless Network

Under the background of intelligent home and office environment, the intelligent entrance guard system is in a stage of rapid development, and face with the unique biological characteristics, through the face recognition technology reached the identification function of the access control system provides a new study idea, combined with wireless network to construct intelligent management system, has great implications for research and practice.The in view of the current access control system single function, does not have the network, configuration is in trouble and other characteristics, researching on the face recognition access control system, the introduction of wireless network technology, will face recognition access control system network, intelligent, can through the service to the entire face recognition system of allocation, and no client tedious configuration in a single access control, improve the convenience.1) Through the DLL to receive facial feature information, store face feature information link library, and then through the WPF platform to build a server interactive management platform, to view, modify, delete, and send the data to the wireless network configuration and data.2) Through Wi Fi technology to build a wireless communication network, the forbidden subgraph node and server master node through wireless connection, when embedded access control system starts automatically connect to a wireless network server embedded platform to transmit data over a wireless network to the;3) To build a face recognition access control embedded platform, using +QT4 system UI Linux technology, through the connection of the Opencv library, build a software platform. Using V4L2 to obtain the camera info rmation, through the Haar features to detect the face region, and finally through the Fisher face recognition algorithm to recognize the human face, through the open access control.
