| abstract | An object of the present invention is to provide a flow velocity distribution / flow rate measurement technique capable of automatically observing a surface flow velocity distribution and a flow rate of a river in almost real time. In this flow velocity distribution and flow rate measurement system, when measuring the flow rate of a river, the surface water flow of the river is photographed by video cameras 1A and 1B installed on the river bank, and a water level gauge 2 installed in the river is taken. The water level of the river is detected by the above, the image signal of the surface water flow of the river and the water level data are taken into the analysis device 3 installed on the ground, and the orientation condition parameters and the water level data preset in the analysis device 3 are used. Geometrically corrects the oblique image of the surface water flow of the river into a vertical plane image, performs PIV analysis on the vertical plane image after the geometric correction, and obtains the surface velocity distribution of each section on the virtual transverse line 6 of the river, The total flow rate is obtained using a preset correction coefficient of the average flow velocity, the cross-sectional shape of the river, the water level data, and the surface flow velocity distribution of each section on the virtual traverse line of the river.
