机载LiDAR支持下的实景三维GIS应用研究

Application Research on Realistic 3D GIS Supported by Airborne LiDAR

基于GALAXYPRIME航摄仪获取的LiDAR点云数据和UCXPWA航摄仪获取的影像数据,本文实现了大面积DEM、DSM、DOM等高精度数据快速生产和可视化地形级三维场景搭建,开发了黄河流域(甘肃段)地形级实景三维应用系统,为面向WebGL地理场景的LiDAR点云数据可视化提供了解决方案。

Based on the LiDAR data obtained by the GALAXYPRIME aerial camera and the image data obtained by the UCXPWA aerial camera,this paper realizes the rapid production and visualization of large-area DEM,DSM,DOM and other high-accuracy data and the construction of terrain-level 3D scene.A terrain-level realistic 3D application system for the Yellow River basin(Gansu section) is developed,which provides a solution for the visualization of point cloud data for WebGL geographic scene.
