Flow velocity and discharge measurement software using video images

「Hydro-STIV Cloud」 is a flow velocity and discharge measurement system that uses video images and water level information. In addition to basic functions for measuring flow velocity and discharge, it is equipped with the latest measurement technology, such as a function to correct the wind effects and a function to calculate the velocity distribution of the cross section.

AI Enables High-speed and High Accuracy Measurement

AI (deep learning) enables more stable measurement than conventional methods. Highly accurate measurement can be performed with complete automatic analysis even when obstacles are in the image, such as when there is muddy water, heavy rain with high water, and there is a reflecting light at night and an infrared camera is used.

Comparison of flow velocity and discharge measurements by ADCP(Acoustic Doppler Current Profiler)and Hydro-STIV has confirmed that the measured discharge of the two only differs within about 5%

MEASUREMENT COUNT

In Hydro-STIV Cloud, the number of measurements available is determined by the subscribed plan. Once a flow velocity or discharge measurement is performed in Hydro-STIV Cloud, the video’s identification information is registered, and it is counted as one measurement. The same video can be re-measured as many times as needed without consuming additional measurement counts.
