Method and system for automatic tracking of teachers and students based on a single detection lens

Abstract

The invention relates to a method and system for realizing automatic tracking of teachers and students based on a single detection lens. A student camera is installed on the front wall of the classroom, and a teacher camera and a detection camera are installed on the back wall to read the original image taken by the detection camera in real time; The motion state detection method identifies the effective moving target and the motion state of the moving target, and starts the teacher's camera in the teacher's activity area to track and shoot, and starts the student's camera in the student's activity area to track and shoot; Effective moving target, judge whether there is facial feature information in the moving target and start the teacher's camera to track and shoot after recognizing the teacher's target. The technical solution of the present invention realizes effective identification of teacher and student targets through the video of a detection camera, and determines the attributes of the targets, thereby controlling the corresponding teacher cameras and student cameras to automatically track and shoot.

Description

technical field [0001] The invention relates to the technical field of image analysis, in particular to a method and system for realizing automatic tracking of teachers and students based on a single detection lens. Background technique [0002] The teaching recording and broadcasting system is a hot spot in the construction of educational informationization in recent years, and the automatic tracking and shooting system is a very important subsystem in the teaching recording and broadcasting system. The automatic tracking system realizes the unattended tracking and shooting of the classroom recording and broadcasting system and the automatic switching guide between multiple cameras, making the recording and broadcasting system an automated and intelligent application system. [0003] In the teaching recording and broadcasting system, the automatic tracking and shooting system has been widely used. The automatic tracking and shooting mainly relies on the image analysis techn...

As a result, the project volume is large, the project difficulty is high, and the project cycle is long

[0007] 2. From the perspective of equipment, solving the connection of multi-channel video will inevitably lead to a relatively complex device form. At the same time, satisfying multi-channel video analysis also requires the equipment to have high computing performance support. On the whole, the tracking device has a complex form and high performance requirements. Insufficient equipment flexibility, many hidden dangers in physical connections, etc.

And adopt the tracking system of existing technology obviously can't meet such requirement
