Classroom analysis system and method based on face recognition technology

Abstract

The invention discloses a classroom analysis system and method based on a face recognition technology, and the system comprises an image collection unit which collects an image for classroom analysis through a camera device disposed in a classroom; an image preprocessing unit which is used for preprocessing the image; a face detection positioning unit which is used for segmenting a skin color area in the image by adopting a Gaussian skin color model and accurately detecting a face in the segmented skin color area by utilizing a trained cascaded structure face classifier; an attendance checking unit which is used for comparing a face recognition result with the face features of the students in the background server according to the face recognition result when the attendance checking request is received, recognizing absent students and feeding back the absent students; and a class state monitoring unit which is used for monitoring the class state of each student according to the face recognition result when receiving the monitoring request, giving a corresponding prompt to the student when judging that the student is in a negative state according to the face recognition result, and obtaining corresponding student information from the background server for feedback.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a classroom analysis system and method based on face recognition technology. Background technique [0002] With the gradual rise of artificial intelligence applications, how to apply artificial intelligence to the classroom has gradually become the focus of attention in the education industry. In the teaching process, repetitive labor in teachers' work takes up most of the teachers' working hours. Students' efficient learning in the classroom is also a headache for many teachers, and the artificial intelligence-based classroom analysis system can better help teachers better manage the classroom and teach more efficiently, which has attracted widespread attention. [0003] In the existing technology, the face image recognition system is combined with classroom analysis equipment. Based on face recognition technology, classroom analysis equipment scans and captures ...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, the face image recognition system is combined with classroom analysis equipment. Based on face recognition technology, classroom analysis equipment scans and captures students during class, and the classroom face comparison server scans and captures The pictures in the face database are compared and analyzed, and the attendance results are automatically obtained. The whole process does not require manual participation, which brings a lot of convenience to the students' attendance work, but the existing classroom analysis equipment is generally inconvenient to use. Adjustment, there are certain limitations, and it is inconvenient to use
