Abstract

The invention discloses a method for detecting classroom attention of a student. The method comprises the following steps: acquiring a classroom scene image; positioning a face and calculating an orientation pose of the face; converting a two-dimensional position of the face in the image into a two-dimensional position thereof in a sitting height datum plane in a classroom, and adding a sitting height priori value of the student to obtain a three-dimensional spatial position of the face in the classroom; through combination of the three-dimensional spatial position of the face and the orientation pose of the face, calculating an attention point of the student on a teaching presentation board. The invention further provides a device for implementing the method. The device comprises a first camera, an identity recognition module, a second camera and a monitoring and analysis module, wherein the first camera is used for acquiring a face image of the incoming student at an entrance of the classroom; the identity recognition module is used for acquiring the identity of the student through the face recognition; the second camera is used for acquiring the classroom scene image; the monitoring and analysis module is used for calculating the attention point of the student on the teaching presentation board. After application of the method and the system, the classroom attention of the student can be accurately monitored to help a teacher to adjust the teaching way in time so as 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...
