Description

Technical Field

[0001] The utility model relates to the technical field of hydrological monitoring equipment, in particular to a hydrological vehicle-mounted liftable video flow measuring equipment. Background Art

[0002] With the advancement and development of technology, video surveillance systems are increasingly used in water conservancy and hydrological monitoring scenarios. Floods are a common natural disaster during the flood season. Their existing formation and evolution mechanisms are known from theory and conventional experiments, and there is a lack of actual measurement methods and data under extreme conditions. Among them, video surveillance systems use water surface video images taken by cameras to analyze the size of the motion vector of water flow tracers, use photographic photos instead of on-site measurements, extract the orientation of the flow measuring buoy from the photos through manual identification or computer recognition, and then calculate the water surface flow velocity on the motion trajectory.

[0003] However, in the prior art, when using image processing analysis to detect water flow rate in the target area, due to the very complex on-site conditions, steep slopes, potholes, mud, obstructions, etc. are likely to occur, which may cause the equipment itself and interference factors to affect the detection results, thereby reducing the accuracy of the detection results. Utility Model Content

[0004] One advantage of the utility model is that it provides a hydrological vehicle-mounted, liftable video flow measuring device.
