摘　　要：机载LIDAR技术作为一种方便、快捷、高效的三维数据获取方法,正在逐步得到广泛的认同。目前,机载LIDAR硬件和系统集成发展已比较完善,研究的重点主要集中在数据后处理及应用等方面。结合国际上最新研究进展,系统地介绍了机载LIDAR数据的后处理过程,提出了一种实用的三维城市模型,实现了基于LIDAR数据三维城市模型的快速重建,使该技术能更好地服务于城市信息化建设。Three Dimensional City Model （3DCM） research becomes a hot area in GIS field in recent years. The 3DCM research also has great significance in traffic, terra, mine, survey and other fields, especially in urban planning. The difficulty of acquiring 3D data is the key hamper for the development of 3DCM. Airborne LIDAR can rapidly acquire the 3D position of ground using airplane. It is very economical, efficient and convenient to acquire 3D data. In this paper, a kind of 3DCM is put forward, and the procedure of airborne LIDAR data is explored. The paper realizes the rapid reconstruction of 3DCM based on airborne L IDAR.
