Outline of Final Research Achievements

The goal of this research is to realize the accessibility evaluation of "as-built" environments based on the detailed human behavior simulation. To this end, we propose a method where as-built 3D environment models can be constructed in a fully automatic way from laser-scanned 3D point clouds measured from as-built environments. Additionally, we propose an advanced walking simulation function of the digital human model (DHM) in the as-built environment models. The proposed simulation enabled a DHM to automatically walk utilizing the functions of the global path findings, the walking path location control, the local collision avoidance and the walking motion generation. Moreover, we applied our modeling and simulation algorithms to the complex as-built environments such as a two-storey indoor environment, and an outdoor environment which includes slopes. The efficiency and effectiveness of the modeling and simulation were confirmed.
