Management system of real classroom and manufacturing method thereof

Abstract

The invention discloses a management system of a real classroom and a manufacturing method thereof. According to the system, a projection device is used to project courseware image onto a pure color background. A control device is used to emit a control command to a courseware and control information is formed. Drawing track information of sketching, rubbing and writing on the courseware by a teacher in teaching is collected and compiled in real time through an interactive device. The class audio information of the teacher is collected and compiled in real time through a pickup device. Through a camera, pictures that the teacher teaches in coordination with the courseware projected on project cloth in front of the pure color background is compiled into class video information. Generated information is subjected to collection and image matting processing through a server device, combined with courseware information, the synchronous marking and storage in the time are carried out, and completed real classroom information is formed through synthesis. The system can display content more clearly and vividly, a user can feel the atmosphere of the on-site teaching, the effect of video learning is improved, thus the pictures are more hierarchical and more vivid, and more information can be displayed than actual class.

Description

technical field [0001] The invention relates to the field of multimedia teaching, in particular to a real-scene classroom management system and a production method thereof. Background technique [0002] Distance education is an open education that uses various educational resources and crosses the limitation of space distance through the network, so that education can go beyond school education and widely radiate to the society. It can give full play to the advantages of educational resources and make the best teachers, the best The teaching achievements of the school are disseminated to thousands of households through the Internet. According to the analysis of classroom teaching behavior, students tend to focus on the teacher, so the presentation of the teacher and courseware on the same screen is easier for students to accept and improve the effect of knowledge reception. Therefore, when teachers and students do not conduct teaching activities in the same space (such as o...

Problems solved by technology

[0003] Usually, a camera is used to shoot the teacher's lecture in front of the electronic whiteboard or projection screen. This solution will cause image distortion because the electronic courseware is shot after passing through the electronic whiteboard or projection screen, and the teacher and the courseware cannot be clearly photographed at the same time.

Especially when projecting with a projector, the camera can only capture the diffuse reflection light on the projection screen and the screen, and cannot clearly display the details of the courseware at all. Even if the teacher is teaching in front of the large electronic screen, it will also happen Spatial aliasing produces water ripples and moiré patterns, so the final video students watch is not clear;
