Problems solved by technology

[0004] 1. When the teacher or student tracking camera is used for both high-definition video collection and image positioning analysis, because the shooting range of the camera is limited, when the teacher or student tracking camera has target activities outside the video range, the tracking camera will not be able to track and shoot. The problem is that there is a tracking blind spot in this solution;
[0005] 2. Using the image tracking method of human body characteristics, it is necessary to collect the human body characteristics of the activ

Abstract

The invention belongs to the field of education training course recording and playing, and specifically relates to an image tracking method and a system for teaching. According to the method and the system, image areas of movable targets can be accurately extracted, and image tracking shooting is accurately performed. The tracking method includes: a teacher image auxiliary positioning camera and student image auxiliary positioning cameras respectively acquire data video information of teacher and student areas and send the information to an image tracking processor; the image tracking processor employs the image processing technology, determines whether there are movable targets in the teacher or student areas, determines the specific position of the target, and solves a target image behavior analysis result of the teacher or student areas; the image tracking processor drives a teacher tracking camera or a student tracking camera to rotate or zoom according to the target image behavior analysis result of the teacher or student areas; and the image tracking processor informs a video switching module of the target image behavior analysis result of the teacher or student areas, and the video switching module sends a video switching instruction to a recording and playing server according to a directing switching strategy.

Description

technical field [0001] The invention belongs to the field of recording and broadcasting of education and training courses, in particular to a method and system for tracking images used in teaching. Background technique [0002] At present, in the process of recording and resource sharing of general education and higher education video open classes, high-quality classes or normalized teaching, it is necessary to track and shoot the class in real time. There are two ways of camera tracking: manual tracking and automatic tracking. Manual tracking is to manually drive the camera to track and shoot. Automatic tracking requires an additional tracking processor, which uses infrared or image processing technology to determine whether the teacher or student is standing or moving, calculates the specific position of the moving target, and drives the teacher or student's high-definition pan-tilt tracking camera to track and shoot. There are mainly two tracking methods: infrared track...
