Description

technical field [0001] The invention relates to the technical field, and in particular, to an intelligent detection method and device for water flow velocity. Background technique [0002] The intelligent detection of the water flow velocity of the present invention mainly uses the thermal infrared imaging of the thermal tracer to measure the water flow velocity. For example, in projects such as water transportation, marine rescue, energy development, and water tourism facilities, the importance of water flow detection is self-evident. [0003] At present, the commonly used water flow velocity detection methods mainly include particle image method, correlation method, flow method, etc. Particle image method will affect the propagation of particles when other substances are contained in the water flow, which will easily reduce the accuracy of the measurement, and the correlation method is difficult to measure in the process. Distinguish the speed of clear water and the speed...
