摘要
随着贵州地区河湖划界工作的开展,遵义地区的河流划界工作也拉开帷幕。文章针对这一现状对航空摄影测量、无人机航空摄影测量技术原理以及河湖划界勘测作业进行研究,提出了基于低空无人机航空摄影测量为基础数据的河湖确权作业流程,主要包括飞行准备,控制网布设,内业数据处理,数字线划图、数字正射影像图及数字表面模型生产以及各个数据在河湖划界工作中的应用,从中总结经验,为河湖划界工作寻求更加高效快捷的作业方式。
With the development of river and lake demarcation in Guizhou,the river demarcation work in Zunyi area has begun.In view of this situation,the principles of aerial photogrammetry,unmanned aerial vehicle(UAV)aerial photogrammetry and river-lake demarcation survey is studies this paper.The operation process of river and lake rights confirmation based on low-altitude UAV aerial photogrammetry data is put forward,which includes flight preparation,control network layout,internal data processing,digital line drawing,digital orthophoto image and digital surface model production,as well as the application of each data in the work of river-lake demarcation.
