介绍机载激光雷达的点云数据获取与处理流程,总结其关键技术,从中可以预测未来遥感与GIS技术在数据获取方面的发展趋势,即借助机载激光雷达,再现真实三维场景。
This paper introduces the process of acquiring and processing point cloud data of airborne lidar and summarizes its key technologies, from which we can predict the development trend of future remote sensing and GIS technology in data acquisition. That is, using airborne lidar to reproduce the real three-dimensional scene.
