倾斜摄影测量及机载雷达在地形图绘制中的综合应用

基于无人机倾斜实景模型的数据采集,目前已经广泛用于基础测绘、地形图绘制、城市规划和土地确权等各类业务。而对于植被茂密的区域,可见光摄影测量则展现出短板,而激光雷达可以穿透部分植被,获取真实地表三维点云数据,将倾斜摄影测量和雷达扫描二者的成果相结合,将大大提升三维实景模型的精度,从而提高大比例尺地形图的成图精度,该文以实例简要介绍倾斜摄影测量和机载雷达综合成图的方法。

Data acquisition based on UAV tilt model has been widely used in basic surveying and mapping,topographic mapping,urban planning,land rights determination and other services.For areas with dense vegetation,visible light photogrammetry shows shortcomings,while LiDAR can penetrate part of the vegetation to obtain 3D point cloud data on the real surface,combining the results of tilt photogrammetry and radar scanning,which will greatly improve the accuracy of the 3D real scene model,so as to improve the mapping accuracy of large-scale topographic maps.This paper briefly introduces the method of tilt photogrammetry and airborne radar integrated mapping with examples.
