Embodiment Construction

[0016] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific examples.

[0017] Such as figure 1 Shown is a schematic diagram of the classroom environment, the classroom is a lecture hall, and teacher 1 is teaching on the podium; the pentagon 10 in the figure represents the students who are listening normally, and the triangle 11 represents the students who are distracted, and they are randomly distributed in the classroom area. Because it is a lecture hall, there is no situation where the upper body of the students, especially the face, is covered.

[0018] The classroom is provided with student attention detection camera 2, teaching camera 3, computer 5 and router 4, wherein, student attention detection camera 2 is used to photograph the facial details of all students in class; this detection camera 2 includes RGB zoom camera 6, infrared Ranging camera 7 and pitch / rotation steering gear 8,...

Abstract

The invention discloses a student class attention detection method. The method comprises the following steps: a teaching image of a teaching teacher and a face image of a class student is collected; Aspectral extinction method based on the set depth data extracts the state of the eyes of the student in the frame image; the sight orientation of student eyes is calculated; the moment of distractionof the student is recorded in the classroom teaching process, cross comparison with the teaching image is performed, and the cause of distraction of the student is analyzed. The attention condition of the student can be calculated by only extracting the eye state of the student and utilizing the continuity of the position and the eye state of the student in the classroom teaching process. According to the detection method, the video recognition algorithm is optimized, the calculation amount is reduced, the classroom attention condition of each student can be obtained through data unification,the large-area distraction time points of the students and the teaching content of the teacher are compared in a crossed mode, the teacher can find out the lack of teaching, the teaching level is improved, and the teaching quality is improved.

Description

technical field [0001] The invention belongs to the technical field of education informatization, and in particular relates to a method for detecting students' classroom attention. Background technique [0002] Nowadays, technological innovation ability has become the key embodiment of national strength. The innovation and development of science and technology cannot be separated from education. Education, as the cornerstone of knowledge, culture and technology transmission, plays a decisive role in technological innovation. Without education, technological innovation is impossible. rise. Nowadays, traditional classroom education is intertwined with various modern new educational methods such as micro-class education, reverse subject, and online education. However, no matter what form of education is adopted, the key to the quality of education lies in the quality of the classroom, and the key to the quality of the classroom lies in the teacher's ability. The quality of tea...
