摘要
机载激光雷达(LIDAR)测量系统发展迅速,通过其在高速公路项目成图中的运用实践,阐述了该技术的原理及数据处理流程。实践证明,与传统航测作业方法相比,该技术可以节省大量的人力和时间,且能够快速生成高密度、高精度的数字高程模型。
LIDAR technology is developing rapidly.The high accuracy of digital elevation model can be obtained quickly by LIDAR,basing on the highway expansion engineering project;this paper introduces the basic principle and data processing flow of the technology.Comparing with traditional aerophotography technology,the technology can save a mass of manpower and time and can rapidly generate the high density and high precise digital elevation model（DEM）.
