摘要
大渡河流域为中国地质灾害高易发区,已经发现地质灾害隐患点多处,当然机遇与危险往往是共存的,大渡河水力理论蕴藏量丰富也逐渐被发现。大渡河两岸地势险要,植被覆盖较厚,人工测量不便、传统测量精度不足,本文以大渡河上某个流域地区的引水工程为例,在河道两岸进行正射航测、激光雷达测量等工作。选用飞马V10无人机为基本测绘工具,搭载LiDAR22和CAM10载荷,在有限的时间之内,生产出满足要求的数字产品,为山洪泥石流灾害分析,工程设计等提供基础分析资料。
The Dadu River Basin is a highly prone area of geological disasters in China,and many hidden spots of geological disasters have been found.Of course,opportunities and dangers often coexist,and the rich reserves of hydraulic theory in Dadu River are gradually discovered.The terrain on both sides of the Dadu River is difficult,vegetation cover is thick,manual measurement is inconvenient,and the accuracy of traditional measurement is insufficient.This paper takes the water diversion project of a watershed area on the Dadu River as an example to carry out positive aerial survey and laser radar survey on both sides of the river.Feima V10 UAV is selected as the basic mapping tool,carrying LiDAR22 and CAM10 loads.Within a limited time,digital products meeting the requirements are produced to provide basic analysis data for mud-rock flow disaster analysis and engineering design.
