Access Control Method of Face Recognition in Intelligent Park Based on Wireless Communication Technology
Because the traditional card recognition access control system has the risk that the door card is easy to be lost or damaged,which can not meet the prevention and protection functions of door locks in smart parks,this paper proposes a face recognition access control method for smart parks based on wireless communication technology.Firstly,the face images of visitors at the access control end of the smart park are transmitted to a remote server by using wireless communication technology.Secondly,in the server,the face image of the access control terminal is preprocessed by graying,histogram equalization,filtering and denoising.Thirdly,the preprocessed face image features are extracted and matched with the face features stored in the system.Finally,the system sends the opening and closing instructions to the door lock according to the recognition result,so as to realize the face recognition access control in the smart park.The experimental results show that the accuracy of face recognition using the method designed in this paper is as high as 98.5%,which can meet the high-precision requirements of access control in smart parks.
