Automatic roll call system and realization method thereof

Abstract

The invention discloses an automatic roll call system. The system comprises a teacher machine, a face detection module and face identification server. The face detection module comprises a camera device and a face obtaining unit; the camera device is configured to receive control signals from the teacher machine, collect video frames and input the video frames to the face obtaining unit; and the face obtaining unit pre-processes the input video frames, extracts face biological features and non-face Haar features from the video frames, uses a trained classifier to classify the video frames, obtains face information, extracts the face edge according to the typical face length and width proportions, and transmits an obtained face picture to the teacher machine. The teacher machine receives the face picture and transmits the face picture to the face identification server for face identification. Face detection is implemented based on the face biological features and the typical face length and width proportions, an educational administration information management system is connected to carry out face identification of specific library, complex faces can be rapidly and effectively identified, the identification rate is improved, and effective management is realized.

Description

technical field [0001] The invention relates to the fields of computer vision and information management, in particular to an automatic roll call system and its implementation method. Background technique [0002] The school's "truancy" has seriously affected the school's style of study. The "skipping class" here includes those who did not come to class, those who slept in class, those who played with mobile phones in class, those who had a seat in front instead of sitting in the back row, those who arrived late and left early, etc. At present, the implementation of the roll call system for college students in class is a very common way to avoid the above phenomenon, but the effect is not good. One is that the teacher has to take a certain amount of time to roll the roll, which is a waste of resources and time; the other is that the students who "do not work hard" cannot be controlled; the third is that students generally dislike the teacher's roll call; and the fourth is t...

Problems solved by technology

However, it is still impossible to effectively monitor the students who "do not work hard", and the phenomenon of signing in on behalf of them cannot be avoided

Moreover, when the classroom or the number of students in the class is large, it is necessary to install multiple monitoring units, or even to install sensors on each seat, and the wiring is complicated and the cost is high
