摘要
利用无人船技术开展堰塞湖体等传统方式测量困难水域的水下地形数据的采集与监测,能够安全、快速地获取水下地形、断面图、水体库容等信息。本文以翠宏山铁多金属矿堰塞湖应急测量工作为例,介绍了无人船测量系统的组成,并详细阐述了利用无人船开展水下测量的实施与数据后处理步骤。应用结果表明,利用无人船测量系统能够有效避免测量时的安全威胁,为困难水域的水下地形测量提供可靠的数据支撑。
Using the unmanned boat technology to collect and monitor the underwater topography data of the barrier lake and other traditional methods to measure the difficult waters can obtain the information of underwater topography,section map,water storage capacity and so on safely and quickly.In this paper,the composition and function of the unmanned vessel measurement system are introduced,and the implementation and data post-processing steps of underwater measurement with unmanned vessel are described in detail.The application results show that the UAV measurement system can effectively avoid the threat of safety position and provide reliable data support for underwater topographic survey in difficult waters.
