【摘要】：三维激光扫描直接对地球表面进行三维密集采样,可快速获取具有三维坐标(X,Y,Z)和一定属性(反射强度等)的海量、不规则空间分布三维点云,成为数字化时代下刻画复杂现实世界最为直接和重要的三维地理空间数据获取手段,在全球变化、智慧城市、全球制图等国家重大需求和地球系统科学研究中起到十分重要的作用。目前,在传感器技术和国家需求的双重驱动下,三维激光扫描在硬件装备、三维点云数据处理以及应用3个方面取得了巨大的进步,同时也面临新的挑战。本文以三维激光扫描的发展历史为线索,总结了三维激光扫描系统的现状、三维点云数据处理的关键进展以及在测绘地理信息等领域的典型应用,并分析了三维点云数据处理面临的挑战,最后展望了三维激光扫描与点云处理的发展趋势。
[Abstract]:Three-dimensional laser scanning directly samples the earth's surface in order to obtain the massive, irregular spatial distribution of 3D point clouds with three dimensional coordinates and some attributes (such as reflection intensity, etc.). Become the most direct and important means of acquiring 3D geospatial data in the digital age to depict the complex real world, in the global change, intelligent city, Global mapping and other important national needs and scientific research in the Earth system play a very important role. At present, with the dual driving of sensor technology and national demand, 3D laser scanning has made great progress in hardware equipment, 3D point cloud data processing and application, but also faces new challenges. Based on the development history of 3D laser scanning, this paper summarizes the present situation of 3D laser scanning system, the key progress of 3D point cloud data processing and its typical application in the field of surveying and mapping geographic information. The challenges of 3D point cloud data processing are analyzed. Finally, the development trend of 3D laser scanning and point cloud processing is prospected.
