武大AiFlow便携式视觉测流仪在水文监测中的应用实践

Practical Application of Wuhan University AiFlow Portable Visual Flowmeter in Hydrological Monitoring

摘要: 本文开发了一款集成传感器与改进的STIV视觉测流算法相结合的武大AiFlow便携式视觉测流仪，具备机动灵活、便于携带、测量精准等特点。为了验证该测流仪的各项性能，选取天津市、贵州贵阳和广东潮州等地进行了比测实验，结果表明武大AiFlow便携式视觉测流仪与ADCP的流速流量测量误差均在5%以内，验证了测流的准确性。此外，本设备还在四川雅安青衣江参与了防洪演练，达到了较好的效果。由于在操作和施测上具有便捷的优势，武大AiFlow便携式视觉测流仪能够实现各种测流场景下点位的迅速布控与监测。

Abstract: In this paper, a Wuhan University AiFlow portable visual flowmeter is developed with integrated sensors and improved space-time image velocimetry (STIV) visual flow measurement algorithms, which is mobile, flexible, portable and accurate. In order to verify the performance of this flowmeter, the comparative experiments were conducted in Tianjin, Guiyang, Guizhou and Chaozhou, Guangdong, etc. The results show that the errors between the Wuhan University AiFlow portable visual flowmeter and acoustic doppler current profiler (ADCP) are within 5%. In addition, this equipment was also performed better during the flood control exercise in Qingyi River in Ya’an, Sichuan. Due to the convenient advantages in operation and measurement, the Wuhan University AiFlow portable visual flowmeter is able to realize the rapid deployment and monitoring of points under various flow measurement scenarios.
