Abstract(in English) It is well known that the calculation time of ray tracing simulations is dominantly determined by the number of surfaces and edges of environmental objects. In this study, we derive the simplified modeling of the urban environment around Kokura station using image processing technologies such as closing operation in morphology and convex hull approximation. Moreover, we utilize the derived urban model for ray tracing simulation and investigate its acceleration effect and accuracy with respect to the received power level.
