机载激光雷达点云数据地面滤波算法综述
A review of ground filtering algorithms for airborne LiDAR point cloud data
摘要
Abstract
As a brand-new method in the field of remote sensing information acquisition,airborne light detection and ranging(LiDAR)technology can quickly and accurately obtain ground three-dimensional(3D)coordinate information and plays an increasingly important role in topographic mapping,environmental monitoring,forest protection,and urban 3D modeling.As the core link of extracting digital elevation models,ground filtering technology has been extensively studied by a large number of Chinese and foreign scholars.On the basis of previous studies,this paper carried out systematic sorting and summary.It briefly introduced the development status of the airborne LiDAR system,then discussed the development history of ground filtering technology,and made systematical classification.Finally,the shortcomings of the current ground filtering algorithm were summarized,and the development trend in this field in the future was prospected.关键词
