Abstract:An intelligent access control system was implemented based on the face recognition technology resources of Baidu cloud platform. Using the face recognition cloud service platform for real-time face analysis, it was not only convenient to use, but also ensured the validity and accuracy of the recognition data. The system also realized the real-time message reminder function based on email and WeChat. The system was divided into two parts: hardware and software. The hardware part of the system took Raspberry Pi 3 B+ as the control core, which was connected with camera, stepping motor, control circuit, touch button circuit and other modules; The software part based on Baidu cloud platform constructed the information management and control system in different operating environments. The system was tested via the application scenario simulation, and the results show that the system ran reliably, the external modules and system circuit ran well. What's more, the recognition accuracy was greater than 97%, and the average response time of the motor was 1.3 s, the functions of message remote receive and dispatch, information management and control system were executed normally. There was no abnormal error in the test process. The final effect of the system reached the expected goal, which could provide reference for the relevant design.
