摘要
河湖健康评价是加强河湖管理及保护的基础性工作.基于无人机低空摄影测量技术可有效评价河湖物理结构健康情况,为河湖健康评价提供支持.以湖北省蛮河为研究对象,介绍了无人机低空摄影测量技术在河湖物理结构评价流程处理、数据获取中的应用.结果表明,蛮河物理结构总体得分为74 分,属于亚健康状态.无人机低空摄影测量技术能较好地应用于河湖健康评价工作,大大提高工作效率,降低作业人员劳动强度,保障作业人员安全,降低作业成本.
Abstract
River-lake health assessment is a fundamental work to strengthen river-lake management and protection.Low altitude photogrammetry technology based on UAV can effectively evaluate the health of river-lake's physical structure,and provide technical support for river-lake health assessment.With Manhe River in Hubei Province as research object,this paper introduces the application of UAV low altitude photogrammetry technology in the processing and data access of river-lake's physical structure assessment.Results reveal that the overall physical structure of Manhe River scored 74,indicating a sub-healthy state.UAV low-altitude photogrammetry technology works well in river-lake health assessment,with improved work efficiency,operator safety,and reduced labor intensity of operators and operating costs.
