On-line synchronization classroom intelligent tracking method and system

Abstract

The invention provides an on-line synchronization classroom intelligent tracking method and system. The method comprises the following steps: an image collection camera collects video data information of moving objects and sends the collected video data information to a behavior analysis processor; the behavior analysis processor analyzes the received video data information, obtains an analysis result, and sends the analysis result to a tracking controller; and the tracking controller determines a corresponding tracking camera to carry out tracking shooting on the target objects according to the obtained analysis result. According to the on-line synchronization classroom intelligent tracking method and system, sharing of tracking resources is realized; and accurate tracking shooting is carried out on teachers and students.

Description

technical field [0001] The invention belongs to the field of online synchronous classrooms, and in particular relates to an online synchronous classroom intelligent tracking method and system. Background technique [0002] In the practical application of recording and synchronizing classrooms in high-quality classrooms, it is necessary to realize real-time tracking of teachers and students by cameras. There are two current solutions: one is manual tracking, where the operator manually controls the camera to track the teacher; the other is automatic tracking through the system. In order to achieve tracking, generally, a tracking camera is installed at the podium end of the classroom, facing the students, for tracking the students; a tracking camera is installed at the other end of the classroom, facing the podium, for tracking the teacher. [0003] The above scheme has the following problems: [0004] 1. The teacher's tracking camera does not track the students, and the stu...

Problems solved by technology

[0004] 1. The teacher's tracking camera does not track the students, and the student's camera does not track the teacher, which leads to the inability to share tracking resources. To track the teacher from multiple angles, it is necessary to add a teacher's tracking camera, and it is likely that the student tracking camera is idle at this time (no student movement needs to be tracked)

[0005] 2. When the teacher walks off the podium and enters the student area to interact with the students, the teacher’s standing direction may not always be facing the teacher’s tracking camera, which leads to the tracking of the teacher’s screen from the back or side, which seriously affects the use effect

However, when teachers give lectures, they often improvise and need to show some materials temporarily. However, the materials prepared by the teacher are not convenient to input into the computer or put them into the physical projector, which brings great changes to the teacher's display of materials.
