摘要 点云滤波是LiDAR制图应用中的一个重要模块,即从地形测量点云中分离出地面点与非地面点。在GIS空间分析和空间关系运算的基础上,提出了以空间格网索引结构组织离散点云的方法。同时建模实现对离散点云处理的渐进式形态学滤波算法,最后通过定量分析论证了滤波算法的可行性以及滤波效果。 Point cloud filtering,separating ground point and non-ground points,is an important module of Li DAR mapping application. Combine GIS spatial analysis and spatial relationships calculation,spatial grid index structure is proposed to organize points, and also a model to achieve the progressive morphological filtering algorithm. Finally,the quantitative analysis is taken to demonstrate the feasibility,precision and filtering effect of the filtering algorithm.
