摘要
点云滤波是地面三维激光扫描数据处理的重点和热点问题,也是点云数据处理的一项关键工作。本文在阐述目前几种主要的点云滤波方法的基础上,着重探讨了基于TerraScan软件的点云数据处理方法,如误差点剔除、点云分类、模型重建等。经实验数据分析取得了良好的滤波效果,能有效滤除点云噪声,同时很好地保持了地形特征。
Point Cloud is a three-dimensional laser scan data processing ground focus and hot spots,point cloud data processing is a key work.several key points of the current cloud filtering method,based on focused on the software-based TerraScan point cloud data processing methods,such as the error point removed,point cloud classification,model reconstruction.The experimental data obtained a good filtering effect,can effectively filter the point cloud noise,while maintaining its edge features.
