Design and Implementation of Classroom Attendance System Based on Image Recognition Technology

With the rapid development of educational informatization, traditional classroom sign-in methods (such as paper sign-in, card sign-in, etc.) have gradually shown problems such as low efficiency and easy cheating. In order to improve the efficiency and accuracy of classroom sign-in and reduce the management burden of teachers, this paper proposes a classroom sign-in system based on image recognition technology. The system uses face recognition technology to realize students' automatic sign-in, which not only improves the efficiency of sign-in, but also effectively prevents cheating behaviors such as signing on behalf of others. This paper introduces the software design and implementation of the system in detail, including the system logical architecture, functional module structure, administrator platform function ER diagram and the detailed process of system implementation. The reliability and practicality of the system are verified through functional testing, performance testing and user experience testing. The experimental results show that the system can complete the classroom sign-in task efficiently and accurately, providing a new solution for educational informatization.
