Embodiment Construction

[0021] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0022] The augmented reality system developed in this topic can provide necessary supplements to teachers' teaching through the setting of virtual scenes. When teachers are playing slides to give lectures, they may encounter some complex models, such as the dam model in water conservancy, which needs to be explained in various parts; or ancient animals and plants, which need to be properly described ; In physics-related courses, the various movements of objects require students' spatial imagination, which can be solved through the models established by the augmented reality system developed in this project. It is also very simple to use the augmented reality system developed in this project to solve the problem. You only need to add an appropriate model library to the system, and you can show the required scene on the projector whenever you need...

Abstract

The invention provides a virtual teaching system based on augmented reality (AR), suitable for an education system. Through man-machine interaction, virtual objects are superposed on an indicator and are displayed on a projector, thereby conveniently providing various complex models for students; through programs, operations such as transformation and rotation of the models can be realized, thereby facilitating a profound understanding of the models for students. The virtual teaching system based on AR has the characteristics of low cost, convenience in use, simple hardware equipment, etc.

Description

technical field [0001] The present invention relates to a computer graphics technology and a space positioning technology, and in particular relates to an invention in which AR augmented reality technology is applied to education. Background technique [0002] Augmented Reality (AR for short), also known as mixed reality. It uses computer technology to apply virtual information to the real world. The real environment and virtual objects are superimposed on the same picture or space in real time. The traditional product display method is to display the actual product on the spot. This method not only needs to prepare the actual product on site, but also needs to consider many issues, including the transportation cost of the product (such as the product volume is large, the product precision is high It has the characteristics of being afraid of shocks and being fragile, etc.), emergency plans when the product is damaged during the display process, and misoperation by the disp...
