面向地理教学的熔岩流过程可视化

Visualization of Lava Flow Processes for Geography Teaching

本文为学习理解熔岩流过程提供了一个可视化的解决方案,利用深度相机传感器采集可塑地形的基础高程数据,以流体动力学的浅水方程刻画计算熔岩流过程,并通过投影仪实时投影展示在可塑地形表面,最终实现不同影响因素下熔岩流过程的可视化。

In geography teaching,the study and understanding of lava flow process is an important work.The traditional way to describe the state of lava flow process is generally text,pictures and videos.Although it has the advantages of low cost and convenient use,it is difficult to understand and the display of relevant influencing factors of lava flow process is not intuitive.Therefore,providing new methods and means to visualize the lava flow process and intuitively display the lava flow process is of great significance to help learners understand the relevant knowledge of lava flow.This study provides a visual solution for learning and understanding the lava flow process.The depth camera sensor is used to collect the basic elevation data of plastic terrain,describe and calculate the lava flow process with the shallow water equation of fluid dynamics,and display it on the surface of plastic terrain through real-time projection by projector,so as to finally realize the visualization of lava flow process under different influencing factors.
