diplomsko delo visokošolskega študijskega programa
Abstract
Z napredovanjem računalniške tehnologije se zadnje čase pojavlja čim več različnih fizikalnih simulacij, med katere spadajo tudi simulacije dinamike tekočin. Enačbe Navier-Strokes opisujejo takšno gibanje tekočin v 3D prostoru, katerih diskretizacija in reševanje na CPU porabi veliko časa. Zato bi si želeli lažjo in hitrejšo metodo za tovrstne simulacije. V diplomskem delu smo predstavili implementacijo reševalnika enačb plitve vode, ki opisujejo gibanje tekočin v 2D prostoru. Reševalnik smo uporabili za predvidevanje poplavnih območij nad 2.5D mrežo zgrajeno iz 3D oblaka točk. Ta množica točk običajno predstavlja realna površja, ki so bila posneta s tehnologijo LiDAR. Tako je v razvitem orodju mogoče predvidet ogrožene predele, ki bodo poplavljeni v realnem času.

Secondary title: |
AN ALGORITHM FOR FLOODING AREA PREDICTION USING LiDAR DATA |
Secondary abstract: |
With the recent advances of computer technology there are many different physical simulations, including simulations of the fluid dynamics. Navier-Strokes equations describe such fluid motion in 3D space. Solving Navier-Strokes equations on CPU is a time consuming task. Because of that simplified method is necessary for the CPU simulation. In this diploma thesis an implementation of the solver for shallow water equations (SWE) is presented. The solver for predicting flooded areas on 2.5D grid constructed from the point cloud is used.
These points usually represent real surfaces that have been scanned with LiDAR technology.
