摘要 随着空间数据应用领域的不断扩展,空间数据的获取和处理成为研究学者的热点问题。20世纪70年代机载雷达测量技术以一种主动式、快速、精确的新型遥感测量方法应运而生,本文主要研究激光扫描数据后处理技术中的滤波分类方法,并通过Terrasolid软件进行点云数据处理,结合具体实例进行粗差剔除,滤波分类等操作。在此过程中,通过设定不同的滤波分类参数进行精度比较,以实现最好的滤波分类效果。 With the developing of the spatial data application, spatial data acquisition and processing become a hot issue for researchers. In 1970s the airborne LiDAR technology is a new remote sensing measurement method with func- tions of active, fast and accurate. This paper expounds the gross error elimination and filter classification method towards the point cloud data through the Terrasolid software. In this process, it chieved the best filer effect by setting different fil- ter-classification parameters for precision comparation.
