摘　　要：为提高DEM空间分析的教学效果,跨越地形实体和DEM空间数据之间的认知差异,提升对空间分析和可视化方法的理解深度,利用混合现实技术自然的交互方式以及对于3D模型良好的可视化功能,将DEM空间分析的实验教学内容融入混合现实交互环境,设计了混合现实实验环境,其中包括DEM模型、虚拟面板、手势交互、剖面分析、通视分析、光照分析等空间分析功能。在HoloLens2真机上利用其环境感知、全息显示和交互接口进行实验验证,实现了实验教学内容的视听同步和实时沉浸。In order to improve the teaching effect of DEM(digital elevation model)spatial analysis and cognitive differences between terrain entities and DEM spatial data,and enhance the understanding depth of spatial analysis and visualization methods,the experimental teaching content of DEM spatial analysis is integrated into the mixed reality interactive environment by using the natural interaction mode of hybrid reality technology and the good visualization function of 3D model,and a mixed reality experimental environment is designed.It includes the spatial analysis functions such as the DEM model,virtual panel,gesture interaction,section analysis,visibility analysis,illumination analysis,etc.The experimental verification is carried out on HoloLens2 by using its environment perception,holographic display and interactive interface to realize the audio-visual synchronization and real-time immersion of experimental teaching content.
