Ground zero-height rainfall accurate acquisition method and system of weighing type rain gauge

The invention discloses a ground zero-height rainfall accurate acquisition method and system based on weighing type rain gauges, and the method comprises the steps: spatially arranging eight rain gauges of the same model, specification and batch in four groups, and configuring video and wind speed environmental quantity monitoring sensors to form a monitoring system. A lightweight deep neural network model is trained by using measured data of a system to obtain a compensation model of influence of external influence and time on a measured value of a rain gauge, and rainfall correction of four measuring points of an actual measurement space after a rain receiving port of one instrument in each group is closed is obtained through model generalization; and on the basis, a deep learning model is established, so that ground precise rainfall is obtained. According to the scheme, the problems of ground vibration, wind-induced vibration, time drift, temperature drift and incapability of accurately acquiring zero-heig
