基于无人机航测的黄河冰凌监测试验研究

The application of UAV remote sensing system on ice monitoring for Yellow River

冰情监测是黄河防凌决策、水资源优化调度、水工程运行管理的关键环节。随着相关学科的不断发展,现代科技对数据质量要求越来越高,传统方法已不能满足冰情监测的实际需求。采用无人机航测方式,利用其安全高效、人力成本低、可迅速发现凌汛险情及堤防病害等特点,对黄河易发凌汛险情的内蒙古河段进行了多架次的航测。结果表明,所采用的中遥Ⅱ型无人机较好地实现了在复杂环境下的航测过程,冰情数据结果全面、准确,为黄河凌汛险情的预测预报提供了参考,为确保黄河防凌安全发挥了积极作用。

Ice monitoring is a key link to the process of ice decision-making, water project operation management and water resources optimization scheduling. With continuous development of related disciplines, modern science and technology demand more and higher quality data. Traditional methods can＇t meet the actual demand of monitoring of the ice disasters. In this paper, UAV is adopted to monitor ice disaster and dangerous levee due to its safety, efficiency and low labor costs. The Yellow River in Inner-Mongolia reach was surveyed using UAV aerial system, where is prone to ice flood danger. The results show that the adopted remote aerial vehicle well implemented aerial process in the complex environment; ice data results are comprehensive and accurate, which provides reference for ice flood forecasting and plays a positive role in ice flood security of the Yellow River.
