摘要
为解决山区测绘的高程问题,本文利用机载激光雷达采集了山区点云并通过点云滤波的手段获取了山区地表点的高程数据,通过实验验证和分析可知,机载激光雷达在山区的地表点云有着很高的精度和密度,能够很好地满足山区地形测绘的要求。
In order to solve the elevation problem of mountain area surveying,the point cloud is collected by airborne LiDAR and the elevation data of mountain area surface point is obtained by point cloud filtering. Through experimental verification and analysis,the surface point cloud of airborne LiDAR has high precision and density in mountainous areas,which can meet the requirements of mountain topographic survey.
