Simplification method of 3D point cloud data for ray trace simulation in indoor environment

Abstract

With the advent of IoT (Internet of Things) services in recent years, various industries are now working towards operating wireless networks and this in turn gives rise to the need for radio propagation simulations. However, in order to obtain reliable simulation results, an accurate model of the environment is often needed. This paper proposes a method for generating a plane model automatically, for use in ray tracing simulations from 3D point cloud data in order to ease the burden of creating models manually. Ray tracing simulation results using the generated model are compared with measurements and the comparison shows that the trend of normalized received power is similar.
