AI Technical Summary

Technical Problem

The current flood simulation in the "four-prevention" twin scenario of flood control has problems such as poor visualization of flood simulation and loose integration of the engine and water conservancy professional models, resulting in more visual appeal than practicality in actual applications.

Method used

A 3D flood visualization method based on image access to inundation model results is adopted. By generating elevation images of the model area, constructing a texture image matrix, converting inundation grid elevation values ​​and performing multi-threaded calculations, and combining GPU Shader technology to perform 3D dynamic flood simulation, the mapping and rendering of water depth and flow direction information are achieved.

Benefits of technology

It significantly improves the simulation fidelity of the flood process, reduces the amount of network transmission data, improves the efficiency of flood status updates, and realizes the intuitive display of water surface fluctuations and flood flow direction, enhancing the simulation effect of the flood process.

Abstract

The present invention discloses a method for three-dimensional flood visualization based on image access to inundation model results, belonging to the field of three-dimensional flood visualization technology. In this invention, in view of the drawbacks of traditional GIS three-dimensional flood visualization, such as large amount of network transmission data and complex data processing of model results on the Web side, a flood simulation data storage, transmission and restoration technology based on image technology is proposed. The result data such as grid vertex elevation, water depth, flow velocity, flow direction, etc. are stored as color components and transmitted through texture images, which reduces the amount of network transmission data and greatly improves the efficiency of flood status update during the inundation process. On the Web side, Shader technology is used for flood rendering visualization, which greatly improves the flood visualization presentation capability and promotes the important transformation of the flood simulation twin scene from "good-looking" to "easy to use".
