Simulating a Walk of Digital Human Model Directly in Massive 3D Laser-Scanned Point Cloud of Indoor Environments

Abstract

Recently, human behavior simulations in 3-dimensional environment models have been enabled by the advance in computer performances. However, manually building the 3D models for the simulations are still costly and time-consuming, and the resultant models are sometimes inaccurate and do not necessarily reflect as-built environments. The final goal of our research is to realize the accessibility evaluation of “as-built” environments based on the human behavior simulation. To achieve the goal, in this study, we developed a technology where as-built 3D environment models could be constructed in a fully automatic way from laser-scanned 3D point clouds measured from as-built indoor environments. Additionally, we realized a basic walking simulation function in the as-built environment model represented by the point clouds. The modeling and simulation efficiency and accuracy were evaluated.Keywordshuman behavior simulationlaser scanning3D point clouds
