Dynamic broadcast system for postgraduate classrooms based on video surveillance
In order to save the time of students looking for a free classroom,the number of students in the classroom is broadcast in real time,and the dynamic broadcasting system based on video surveillance is developed to meet the needs of students.In the video surveillance system,the use of digital image processing technology to identify visitors flow is a hot issue in domestic research,involving many core issues in image processing and recognition,including video image real-time acquisition,moving target detection,target tracking,image processing and analysis and other aspects.Based on the network structure of YOLOv5s,this paper proposes a student counting method in the classroom scene based on YOLOv5s,so as to identify whether the classroom is an idle classroom,submit the statistical information to the system for background processing,arrange the idle classrooms in descending order according to the idle seats,and push it to the client announcement terminal.You can see the number of free classrooms,the number of free places and other information,to achieve real-time broadcast of the number of people.
