Abstract

The invention discloses a method for detecting a student's classroom attention, specifically: collecting a scene image in the classroom; locating a human face and calculating the orientation posture of the human face; converting the two-dimensional position of the human face in the image to its sitting height in the classroom The two-dimensional position of the reference plane and the prior value of the student's sitting height are added to obtain the three-dimensional space position of the face in the classroom; combined with the three-dimensional space position of the face and the orientation of the face, the student's attention point on the teaching display board is calculated. The present invention also provides a device for implementing the above method, including: a first camera, used to capture the face image of the students entering the classroom; an identity recognition module, used to obtain the student's identity through face recognition; a second camera , used to collect classroom scene images; monitoring and analysis module, used to calculate the students' attention points on the teaching display board. The application of the invention can accurately monitor the attention of students in the classroom in real time, and help teachers adjust the teaching method in time to improve the teaching effect.

Description

technical field [0001] The invention belongs to the technical field of educational informatization, and in particular relates to a method and system for detecting students' classroom attention. Background technique [0002] In traditional teaching, the methods of observation and analysis of teaching behavior are mostly based on manual analysis such as traditional questionnaires or cases. The evaluation results are relatively subjective and require a long period of statistical analysis. Real-time feedback cannot be used to improve teaching. Behavior. If the teacher can understand the students' attention status in real time in the classroom, he can adjust the teaching method in time, which will effectively improve the teaching effect. However, most of the existing classroom monitoring systems focus on monitoring the attendance of students, and rarely involve the analysis of students' attention. Contents of the invention [0003] Aiming at the above defects or improvement n...
