Simulation on flooding, emergency light and escape chute and modeling method for building high-accuracy LOD 3 exterior and interior with textures

Abstract

It is desirable for managers of public buildings to have the models that can simulate the exterior and interior of the buildings they manage in order to prepare for disasters. The simulations using 3D models that rely on existing models are limited in terms of location, time, and accuracy. In this study, in order to create the building high accuracy LOD 3 exterior and interior models with textures, the exterior and interior of the building were surveyed, detailed shapes were created using BIM, and then the data were expanded into GIS and photographs taken with a 360° camera or other device were pasted as textures. These models enable three-dimensional simulations of flooding, the placement of emergency lights, and the deployment of rescue chute. In addition, the textures with the photographs attached makes it possible to identify the location of fire extinguishers.
