摘要
摄影测量与遥感领域,机载激光雷达技术用于基础地理信息数据DEM生产时,处理效率高,更新周期短,具有很多明显优势,但由于可参考借鉴的经验较少,也不可避免地遇到一些问题。本文通过基础测绘项目的生产实践,总结出数据处理过程中问题的解决方法,特别是对点云分类、编辑等方法进行了较为详细的阐述,对实践工作具有较强的指导意义。
The area of photogrammetry and remote sensing, airborne laser radar technology used in the basic geographic information data DEM production, processing efficiency is high, the update cycle is short, has many obvious advantages, but due to less experienced, reference is inevitably encounter some problems, this article, through the base of surveying and mapping production practice of the project, summarizes the problems in the process of data processing solution, especially for point cloud methods such as classification, the editor has carried on the detailed elaboration, has strong guiding significance to practice work.
