Flood monitoring information extraction method and device, equipment and storage medium

Abstract

The invention provides a flood monitoring information extraction method and device, equipment and a storage medium and relates to the technical field of water conservancy application. The method comprises the following steps that: a to-be-predicted image is input into an image semantic segmentation network model, and obtaining a water body information distribution diagram of the to-be-predicted image, wherein the image semantic segmentation network model is obtained by training based on a training set corresponding to a sample image and a verification set, and the training set and the verification set are obtained by dividing a data set obtained by overlapping and combining a first polarized image, a second polarized image and a spectral feature image, the first polarized image and the second polarized image are obtained after polarization processing is conducted on the sample image, the spectral feature image is obtained through derivation processing on the first polarized image and the second polarized image. Flood monitoring information can be extracted more accurately, meanwhile, the application range of the method and device is wider, and the method and device have better popularization value.

Description

technical field [0001] The invention relates to the technical field of water conservancy applications, in particular to a flood monitoring information extraction method, device and storage medium. Background technique [0002] As one of the natural disasters that seriously threaten the survival and development of human beings, flood disasters have the characteristics of fast occurrence, high frequency, wide range of influence, inundation of farmland, residential areas and other areas, endangering social stability and unity, and seriously affecting people life safety, resulting in a large amount of economic losses. According to the "China Flood and Drought Disaster Bulletin" issued by the Ministry of Water Resources, flood disasters have brought great challenges to my country's economic development. In order to reduce the losses caused by floods to the people and the country, it is of great significance to monitor the floods timely and accurately and obtain the spatial and t...
