Zusammenfassung:The invention discloses a flow velocity and flow measuring device based on an image sensor and a measuring method thereof. The flow velocity measurement device comprises an illumination unit, an optical imaging unit used for shooting a velocity measurement area, an image sensor and an image processing and calculating unit, all the parts are connected to form an integrated probe, the integrated probe can be directly placed in fluid for measurement, and a matched illumination structure is designed. As the measurement distance is short and the requirements on the power and directivity of a light source are low, a semiconductor light source can be adopted, an image can be amplified, and the requirements on tracer particles are reduced. One or more flow velocity measuring devices based on the image sensor are used in the flow measuring device, and the flow is calculated by measuring the flow velocity of multiple points in the pipeline. The device is high in precision, low in cost, small in interference and easy an
