摘要
随着无人机技术在风电场地形图测绘中的广泛应用,随之带来DEM精度的不断提高。但是在存在大量植被和居住地的地区如何剔除非地面点将DSM转化为DEM则显得尤为棘手。通过简单分析几种常用的LiDAR点云数据滤波技术,比较优劣后深入探讨布料模拟滤波算法,将布料模拟滤波算法应用于风电场地形图等高线的绘制,为更好地解决采用无人机航测技术进行风电场地形图测绘提供一种解决思路。
With the wide application of UAV technology in wind farm topographic mapping,the accuracy of digital elevation model has been improved continuously.However,in areas where there are a lot of vegetation and residential areas,it is particularly difficult to remove non-terrain points and convert digital terrain model into digital elevation model with high accuracy.This paper briefly analyzes several commonly used LiDAR point cloud data filtering technologies,compares the advantages and disadvantages,and then discusses the cloth simulation filtering algorithm in depth.The cloth simulation filtering algorithm is applied to the drawing of wind farm topographic map contour,providing a solution for better solving the problem of using UAV aerial survey technology for wind farm topographic map mapping.
