Study and Design of Intelligent Management System for Student’s Attendance

ABSTRACT

Aiming at the problems existing in the work of traditional student’s attendance, using computer technology combined with the more advanced technology of face recognition, a real-time processing intelligent management system for student’s attendance has been studied and designed. The system is mainly composed of image collector and attendance management computer. Its control core is the digital signal processor TMS320DM6437, and peripheral circuits of TMS320DM6437are given. In the image collector, the collection of student’s face image is completed by the CMOS camera. After collection, the face image is two valued, noise filtered, and the face region is fixed roughly. And then through vertical and horizontal projection, eyes are positioned precisely, according to the geometric characteristics of human face. The face image is cut out, and then through the image normalization and histogram equalization, the standard face image of the student is obtained. Finally, the standard image is decomposed by two-layered wavelet, feature vectors of the student’s image are extracted, and, in this way, student’s attendance is completed. The attendance results are stored in the memory, at the same time, the results are sent to the attendance management computer through the network. When a student is absent, messages are sent to his mobile phone through the wireless communication module in image collector. In the image collector, the C language is used to program, and the control function of attendance management computer is achieved by Visual Basic.
