The invention discloses a teaching attention monitoring system and method based on vision. The invention belongs to an intelligent image identification method. The system comprises a first camera, a second camera and a third camera; the first camera, the second camera and the third camera are respectively connected to the central processing unit; the central processing unit is also connected to the background video analysis unit; the first camera, the second camera and the third camera are used for being installed in a teaching area in a delta shape. Video images in a teaching area are collected from different directions through a first camera, a second camera and a third camera; the central processing unit and the background video analysis unit respectively identify the intersection pointbetween the sight line of the human body target in the video image and the blackboard wall at the front part of the teaching area; therefore, the concentration degree of the students in the monitoring video of the teaching area is determined, a teaching manager can know more detailed information through the monitoring video, and the teaching quality can be improved.
Description
technical field [0001] The invention relates to an intelligent image recognition method, and more specifically, the invention mainly relates to a vision-based teaching attention monitoring system and method. Background technique [0002] With the continuous development of video surveillance technology, in some special scenes, people's monitoring needs in the monitoring area are no longer limited to live shooting, but want to use the captured images to analyze and identify the state of the target in the scene. In this way, the utilization efficiency of surveillance video can be enhanced, and more valuable information can be excavated from it, providing more data reference for managers. For example, the monitoring system used in the classrooms of primary and middle school students, due to the poor self-control and large number of such people, it is very difficult to pay attention to the concentration of each student from the monitoring video, which hinders teaching management ...
