A method and system for online synchronous classroom tracking control

Abstract

Provided are an online synchronous class tracking control method and system, comprising the following steps: an image analyzing video camera collects the video data information of a moving target and conducts analysis so as to obtain the analysis result and transmits the analysis result to a tracking controller; the tracking controller determines, according to the obtained analysis result, the corresponding tracking video camera to track and film the target object; if the storage volume of the corresponding tracking video camera reaches an early warning value, a warning request is transmitted to the tracking controller; the tracking controller receives the warning request, and determines the target content to be deleted and notifies the corresponding tracking video camera; the tracking controller or the corresponding tracking video camera selects, according to a pre-set policy, a target tracking video camera to be switched to for tracking and filming the target object. The present invention enables tracking resources sharing, tracking video camera load balancing, and also accurate tracking and filming of teachers and students.

Description

technical field [0001] The invention belongs to the field of online synchronous classrooms, in particular to an online synchronous classroom tracking control 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 student's camera do...

AI Technical Summary

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.
