A cellular navigation mesh, called an adaptive grid, is constructed from a top-view range image of a three-dimensional urban model. A navigation graph can then be extracted from this adaptive grid for path planning. We compare our approach with two popular navigation mesh-generation approaches and obtain promising results in terms of path accuracy and memory cost.EnglishAdaptive gridsCrowd simulationImage processingNavigation meshesPath planningSpace subdivisionArticle10.1117/1.OE.52.2.027002
