Virtual-real fusion teaching aid automatic generation method

Abstract

The invention belongs to the field of teaching application of a mixed reality technology, and provides a virtual-real fusion teaching aid automatic generation method, which comprises the steps of (1)acquiring information of a real teaching environment; (2) generating a virtual teaching aid; and (3) fusing the virtual teaching aid with the real environment. According to the virtual-real fusion teaching aid automatic generation method, a scheme of real environment information collection, virtual teaching aid generation and real environment fusion is provided for meeting the requirements of a new generation of intelligent teaching environment, and according to the teaching requirements in an enhanced teaching scene, the method includes establishing a set of method for acquiring a 3D real-time map, teacher interaction behaviors and voice commands from a teaching environment; automatically generating a hierarchical relationship between the virtual teaching aid model and components thereofaccording to the machine language; and dynamically rendering the virtual teaching aid model and the annotation information thereof to realize fusion with a real teaching environment.

Description

technical field [0001] The invention belongs to the field of teaching application of mixed reality (Mixed Reality, MR) technology, and more specifically relates to a method for automatically generating teaching aids with fusion of virtual and real. Background technique [0002] Technologies such as 5G, VR / AR / MR, and holographic projection are profoundly changing the traditional teaching environment. Building a new generation of teaching environment that integrates virtual reality and online and offline has become a new mission for the future education model in the era of artificial intelligence. In the teaching process, virtual teaching aids can transform abstract knowledge into concrete and visualized content, reduce the difficulty for students to master complex and abstract concepts, and improve observation, practice and scientific thinking ability. The hybrid enhanced learning environment based on MR technology can build an interactive feedback information loop between vi...

Problems solved by technology

[0003] However, there are still many problems in the generation of virtual teaching aids: (1) the form of expression is more complex. Compared with traditional teaching aids such as textbook pictures, blackboard hand-drawn graphics, and real objects, the presentation of 3D interactive models or panoramic videos is more complicated; (2) the generation of The method is not smart enough, creating virtual teaching aid models through 3D modeling an
