摘要/Abstract

摘要： 结合增强现实技术的发展，在虚拟地理环境发展的基础上，提出了“增强地理环境”的概念和虚实融合框架；主要研究了虚拟地理过程与三维打印模型沙盘融合的关键计算与可视化技术，具体包括虚拟地理空间与现实地理空间的坐标匹配、遮挡处理等算法，并以学校火灾人群疏散为案例，实现了人群疏散模拟虚实融合的增强地理环境可视化原型系统。通过系统测试和人员体验调查统计分析，证明了增强地理环境可视化技术的可行性和人群疏散模拟应用交互展示的创新性。

Abstract: Combining with the development of augmented reality (AR) technology,this paper proposed a conceptual framework about augmented geographic environment (AGE) based on the development of virtual geographic environments (VGE).Key computing and visualization technologies of the fusion of virtual geographic process and 3D printing realistic model,including the coordinate matching technology of virtual geospatial space and real geographical space and the technology of occlusion processing,are investigated.In the case of crowd evacuation,we implemented a prototype system for crowd evacuation simulation based on the AGE.Then we proved the novelty of the AGE by systematic testing and document investigation.We believe that the AGE is one of the future development of VGE.

Key words: augmented geographic environments, virtual geographic environments, augmented reality, virtual reality, crowd evacuation simulation, visualization
