中文摘要：

用于测绘的激光雷达技术的研究与应用在国际上已经经历了二十多年的发展历程。作为一种多平台主动探测技术，激光雷达已经和光谱成像技术以及合成孔径雷达一起构成当代遥感观测的核心技术体系。文章尝试对基于激光雷达数据的数据处理、信息提取及应用等进行综述，内容涉及点云分割、地物识别、点云滤波以及实际应用的最新研究进展。

英文摘要：

Research and application of LiDAR （Light Detection And Ranging） technology for surveying and mapping has been carried out for more than two decades. As a multi-platform active detection technology, nowadays LiDAR, together with Imaging Spectrometer and InSAR, has become a core part of modern remote sensing technology. In this paper, we try to survey recent developments of LiDAR processing, information extraction including point cloud segmentation, ground object recognition, point cloud fihering and practical application.
