Method and system for realizing automatic tracking of teacher and student based on single detection lens

Abstract

The invention relates to a method and a system for realizing automatic tracking of a teacher and students based on a single detection lens. The method comprises the following steps: installing a student photographing device at the front wall of a classroom and a teacher photographing device at the back wall; after that, accessing the original images photographed by the photographing devices in real time; according to the human body moving state detection method, identifying an effective moving object and the moving state of the moving object and initiating the teacher photographing device for tracking photographing in the activity zone of the teacher and initiating the student photographing device for tracking photographing in the activity zone of the students; if an effective moving object appears in the intersecting area between the activity zone of the teacher and the activity zone of the students, determining whether there exists human face characteristic information in the moving target or not and initiating the teacher photographing device for the tracking photographing after a teacher object is identified. According to the technical schemes of the invention, with the videos from a detection photographing device, it is possible to effectively identify a teacher and students, to determine their attributes and to further control the corresponding teacher photographing device and the student photographing device for automatic tracking photographing.

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
