Intelligent simulation method for spatial optimization of silt dam system based on high-resolution images

Abstract

The application discloses a kind of silt dam dam system space optimization intelligent simulation method based on high-resolution image, it is related to silt dam system planning technical field, including the geographic registration after the multiple high-resolution remote sensing images of target river basin, extract three-dimensional terrain information, generate surface deformation elevation difference grid through pixel level difference operation, extract the measured sediment discharge of each sub-basin, and combine with the rainfall data corresponding to different time, construct the sediment transport ratio model of each sub-basin, generate the actual sediment yield contribution intensity spatial distribution diagram of target river basin, it is used as input, in the spatial range of target river basin, with dam system overall service life maximization as target intelligent simulation optimization is carried out, at least including dam site coordinates and dam height dam system space layout parameter is solved, provide a kind of can analyze the dynamic process of river basin sediment yield and siltation, realize river basin sediment yield contribution intensity fine mapping, and can carry out system level optimization to dam system.The method.
