摘要
作为一种获取地表信息、建立三维模型的有力工具,激光雷达技术引起人们的广泛关注并取得快速的发展。其直接获取量测点三维坐标的工作方式使其数据具有某些明显特征。本文从数据内容、种类、分布形式等几方面对激光雷达数据特点进行了总结;结合数据获取方式探讨其形成机制;并对其优、劣势及几个相关问题加以阐述。
LIDAR or Airborne Laser Scanning as a powerful remote sensing technology for survey in different areas, suchar urban forest coastal areas,for instance,has received increasingly intensive attention in the last several years.The paper describes the characteristics of LIDAR data, irregular 3D points cloud, and its advantages and disadvantages. In addition,some issues about LIDAR system and some problems related with such data are also discussed briefly in the paper,which facilitate the understanding of LIDAR data characteristics.
