摘要
无人机航空技术的快速发展为地理空间信息外业数据采集提供了质的飞跃,但随之而来繁重的内业数据处理工作,生产效率提高不明显。如何充分地利用航摄成果快速实现地理信息产品高质量生产是目前业内普遍遇到的难题。本文通过生产实践,研究基于航摄点云分类综合处理方法提取地表高程信息及地形要素的方案,并验证分析该方案应用于水利规划中的可行性,为提高生产效率和工作质量提供参考。
The rapid development of UAV aviation technology provides a qualitative leap for the collection of geospatial information data,but it brings heavy data processing work,and the production efficiency is not obviously enhanced.How to make full use of the results of aviation and fly to realize the production of high quality geographic information products is a common problem in the industry.This paper studies the scheme of extracting surface elevation and terrain elements based on the classification processing method of aviation aerial photogrammetry point cloud through production practice,and verifies and analyzes the feasibility of the scheme in water conservancy planning in order to provide reference for improving production efficiency and work quality.
