AI Technical Summary
Traditional flood monitoring is difficult to effectively cover remote and complex terrain areas. The existing remote sensing methods mainly focus on the static extraction of water bodies. They cannot identify flood events and their states, and it is difficult to quickly capture water changes and their propagation paths.
By extracting multiple typical river sections from the target river section, obtaining the current remote sensing image, identifying whether a flood event occurred in the target river section, and determining the flood status of each typical river section based on the journey. The specific steps include determining the unit length of a typical river section, dividing unit sections, building a water surface set, identifying flood events using the current remote sensing image and water surface set, and determining the run length according to the change ratio of water surface area to identify flood state.
Flood event identification and dynamic monitoring of flood status based on remote sensing images are realized, which can quickly capture water changes and propagation paths, and improve the efficiency and accuracy of flood monitoring in remote and complex terrain areas.
