遥感图像三维可视化在低空磁测飞行辅助设计中的应用

Remote Sensing Image Visualization for Low-altitude Magnetic Survey Flight Aided Design

利用遥感技术、GIS技术和虚拟现实技术,将遥感影像与DEM数据叠加,建立低空磁测飞行工作区三维遥感影像模型。三维模型可将地表植被、河流、湿地等地物分布情况与地形特征清晰的反应出来,并可根据测线设计航线实现模拟飞行,生成三维动画。在飞行工作前期准备阶段,模拟飞行动画可向技术负责人员直观展示地形起伏和地表覆盖情况,指导飞行工作的部署,为大比例尺低空航磁勘查提供决策支持。

The author established low-flying workspace 3D Remote Sensing dimensional model by using the technologies of remote sensing,GIS,virtual reality and superimposing remote sensing images on DEM.The distribution and characters of vegetation,rivers,wetlands and other surface features can be clearly displayed on 3D model.Moreover,based on the measured line design routes,the author can achieve flight simulation and generate 3D animation.During the flight preparation stage,flight simulator animation can clearly show the coverage and surface topography to the technical director,guide the deployment of flying,and provide support for the decision-making of the large-scale low-altitude aeromagnetic research.
