PTV技术在河流流速测量中的实验研究

Experimental Research on River Flow Velocity Measurement Using PTV Technology

针对传统浮标法流速测验技术的不足,引入粒子跟踪测速技术,对河流流速测量进行研究,并对所涉及的空间分辨率,目标检测,目标跟踪,流速计算四个方面技术进行分析。最后就本文方法与传统浮标法在实验室山溪性河流模型上做比对性试验,结果表明两种方法所测量的流速具有较好的一致性,具有解决传统浮标法固有缺陷的能力。

According to the weakness of the traditional buoy method, this paper introduced particle tracking velocity technology to study the velocity measurement of mountainous rivers, and analyzed the related technology, including the spatial resolution, target detection, target tracking, velocity calculation. A comparison experiment was made between the mountainous river model and traditional buoy method. The results show that the two methods have good uniformity of the velocity measurement, and particle tracking velocity technology has potential ability to settle the faults of the traditional buoy method.
