摘　　要：水文站目前常用的流量测验仪器有转子流速仪、声学多普勒流速剖面仪(ADCP)等。由于流速仪法不能在线监测,ADCP易受含沙量和漂浮物的影响,在一些场景上的应用有较大限制,亟需补充新的现代化监测设备,以提升水文装备的易用性、实时性和自动化水平,加强水资源管理能力。视频流速识别技术具备可视化、实时性好、适应性强等特点,可作为流量测验的一种较好的补充手段,用于无人值守水文站,提高水资源管理的感知能力,助力水文现代化。At present,the flow measuring instruments commonly used in hydrological stations generally include current meter,Acoustic Doppler Current Profiler(ADCP),etc.Since the current meter method can not be monitored online,ADCP is easily affected by sand content and floating objects,and the application in some scenarios has great restrictions.There is an urgent need to supplement new modern monitoring equipment to improve the ease of use,real-time and automation of hydrological equipment,as well as water resource management capabilities.The video-based flow rate identification technology has the characteristics of visualization,good real-time performance and strong adaptability.It can be used as a good supplementary means for flow measurement for unattended hydrological stations to improve the perception ability of water resources management and help hydrological modernization.
