摘要
在虚拟地理环境(VGE)中,如何应用全景影像快速搭建场景并实现更自然的交互是系统要考虑的重要问题。针对VGE中多人协同交互的需求,文中提出了一种基于全景影像的沉浸式虚拟场景快速构建方法,对多个虚拟场景之间建立联系的方式进行设计,分析了多人协同交互包含的主要内容和实际操作方式,并提出了在不同虚拟场景之间进行多人协同交互的方式。在此基础上,以虎峪野外地质实习区域为例,开发了基于全景影像的虚拟野外实习考察原型系统。应用结果表明,基于全景影像的沉浸式虚拟场景构建与多人协同交互技术能使教学内容得到有效的展示,充分发挥学生在学习过程中的主动性,在野外大场景实习考察应用方面具有良好的前景。
In a virtual geographic environment(VGE),how to use panoramic images to quickly build a scene and achieve more natural interaction is an important issue for the system to consider.To address the need for multi-person collaborative interaction in VGE,a rapid construction method of immersive virtual scenes is proposed based on panoramic images,which designed the way to establish connections between multiple virtual scenes,and analyzed the main aspects of multi-person collaborative interactions and finally put forward a way of multi-person collaborative interaction between different virtual scenes.On this basis,Huyu field geological practice area is taken as an example to develop a virtual field practice inspection prototype system based on panoramic images.Results show that the immersive virtual scene construction and multi-person collaborative interaction technology based on panoramic images can effectively display the teaching content for teachers,fully mobilize the enthusiasm of the students,thereby further improving the teaching efficiency,which has a good application in the field practice inspection.
