Problems solved by technology

[0002] Educational institutions generally evaluate teachers' teaching efficiency and students' listening efficiency through examinations and after-school assignments. However, the examination method makes the feedback results late, and the examination is usually only a few weeks away, and the timing of supplementary teaching is delayed.
The method of homework makes the authenticity of feedback more uncertain
Moreover, the two methods have no direct and objective proof for evaluating classroom efficiency.

Embodiment Construction

[0024] In the following description, many technical details are proposed in order to enable readers to better understand the application. However, those skilled in the art can understand that without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in each claim of the present application can be realized.

[0025] Explanation of terms:

[0026] Face recognition: A biometric technology for identification based on human facial feature information. A series of related technologies that use a video camera or camera to collect images or video streams containing human faces, automatically detect and track human faces in the images, and then perform facial recognition on the detected faces, usually also called portrait recognition and facial recognition.

[0027] Frontal face: When the student's face is basically facing the camera, it is considered to be a frontal face.

Abstract

The invention relates to the technical field of education informatization, and discloses a classroom efficiency detection method and system. The method comprises the following steps of: shooting an image comprising all the students in a classroom; obtaining a sub-image corresponding to each human face area in the shot image; and recognizing the sub-images and judging whether the corresponding human face areas comprise front faces or not, and if the judging result is positive, carrying out classroom efficiency statistics according to front face information. According to the method, the front faces of all the students during the teaching of a teacher are judged by utilizing human face recognition, so that the classroom efficiencies of the students and the teacher can be detected, the classroom efficiencies can be assessed and the assessment is more perspective.

Description

technical field [0001] The invention relates to the technical field of education informatization, in particular to a method and system for detecting classroom efficiency. Background technique [0002] Educational institutions generally evaluate teachers' teaching efficiency and students' listening efficiency through examinations and after-school assignments. However, the examination method makes the feedback results late, and the examination is usually only a few weeks away, and the timing of supplementary teaching is delayed. The method of homework makes the authenticity of feedback more uncertain. Moreover, the two methods have no direct and objective proof for evaluating classroom efficiency. [0003] Therefore, there is an urgent need for a method and system that can accurately and timely evaluate classroom efficiency. Through this system, the evaluation of classroom efficiency can be automatically obtained immediately after class, and it can have an intuitive proof of...
