面向工程训练的混合现实技术开发与应用

Development and Application of Mixed Reality Technology for Engineering Training

混合现实技术是虚拟现实和增强现实的融合发展,实现了虚拟物体和真实物体实时共存与交互。利用混合现实技术识别实物模型标记物,将虚拟信息叠加到实物模型上,用户在虚拟信息指导下和实物模型进行互动,完成各项实践操作环节,实现了无人指导、虚实结合的工程训练教学。与传统教学方法相比,其提供的信息更直观,内容新颖、互动丰富,且无需学生集中授课,应用场景更多样。在当前新冠疫情下,使用混合现实技术,为实践类课程实现无辅导教学、无集中示范教学,提供了探索和研究的思路。

Mixed reality technology is the fusion development of virtual reality and augmented reality,which makes real-time interaction between virtual objects and physical objects.We identified markers on physical objects by mixed reality technology,and succeed to superimpose virtual information on physical objects.Under the guidance of virtual information,users interacted with physical objects and performed practical operations.Without manual guidance,the combination of virtual and real teaching of engineering training realized.Compared with the traditional method,new method is more intuitive and interactive.Students do not need to gather in classroom and teaching can be performed in different scenes.In current COVID-19 epidemic situation,mixed reality technology provides exploration and research ideas for the realization of no guidance teaching and no centralized demonstration teaching in practical courses.
