摘　　要：机载激光雷达技术作为遥感信息获取领域的全新手段,因具有快速、准确获取地面三维坐标信息的特点,在地形测绘、环境监测、森林防护和城市三维建模等应用领域发挥着越来越显著的作用。地面滤波技术作为提取数字高程模型的核心环节,大量国内外学者对此做了许多专门的研究。本文在前人研究的基础上进行了系统性的梳理和总结,首先简要介绍了机载激光雷达系统的发展现状;随后探讨了地面滤波技术的发展历程,并对其进行了系统分类和梳理;最后,总结了当前地面滤波算法存在的不足之处,并展望了该领域未来的发展趋势。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.
