基于视频的河流表面流速测验方法研究

A Video-based River Surface Velocity Measurement Method

基于视频数据,采用立体几何的分析方法,通过对水面定位质点的分析,进行小河流的流速、流量分析计算,获得了满意的结果。本方法需要投入的人力和技术装备少,分析计算方法简便,适用于野外查勘,可应用于宽度较窄的小河、龙口或溃口水面流速、流量监测,也可用于特殊洪水时的河流断面流速、流量测验。

In order to make the flow velocity and discharge measurement become more efficient and convenient,we studied on the method of measuring small rivers' flow velocity and discharge by analyzing video data and the satisfactory results have been obtained.It shows that the method is simple and suitable for field operation with less personnel and measurement equipment,and can be applied to the water flow velocity and flow monitoring on narrow rivers,cofferdam gaps,or bursts.
