Abstract

The invention relates to the technical field of rainfall inspection, and discloses a rainfall inspection method based on an image recognition algorithm, which comprises the following steps: S1, data reading: firstly, collecting meteorological original data and pictures, then recognizing and reading the meteorological original data and pictures, and sequentially performing image enhancement, image denoising, image filtering, image segmentation, image integration and image binarization processing to obtain a preprocessed image; and S2, data analysis: analyzing the read data, and then setting a precipitation threshold value. According to the invention, the mode forecasting is translated at all angles, so that the variance of the mode rainfall forecasting and the actual condition is minimum, the rainfall falling area, rainfall intensity and form error of the actual condition and the mode are calculated and analyzed, and the problem that the rainfall forecasting capability judgment of a numerical mode is not objective enough is solved; the rainfall error of the numerical mode under different influence systems can be more conveniently understood by a predictor, so that mode correction can be better carried out, and accurate rainfall forecast can be made.

Description

technical field [0001] The invention relates to the technical field of precipitation inspection, in particular to a precipitation inspection method based on an image recognition algorithm. Background technique [0002] For a long time, the serious consequences of natural disasters have made people extremely vigilant, and in natural disasters, except for a few types of disasters such as drought, most of them are more or less related to precipitation disasters, either directly or indirectly. Weather The process is the change process of weather phenomena in a certain area over time. Various weather systems have certain spatial and temporal scales, and systems of various scales interweave and interact with each other. The combination of many weather systems constitutes a large-scale weather situation and the hemispheric or even global atmospheric circulation. The weather system is always in the process of continuous birth, development and extinction, and has its corresponding ...
