The Ministry of Land, Infrastructure, Transport and Tourism is promoting Project PLATEAU, measures for the maintenance, utilization and adoption of open data of 3D urban models. In fiscal 2022, 3D urban models for 56 cities across the country were maintained and if the maintenance progresses to indoor spaces, further use expansion can be expected. To realize this, it is necessary to establish a method to create 3D models to which barrier information, etc., have been given by measuring indoor spaces easily.
This research created a method to create indoor 3D models by the voxel representation of point cloud data. As a result, through a demonstration experiment, the created method clarified that the problem could be solved that the density of point cloud data acquired with LiDAR of a portable terminal was non-uniform and the background was permeable, barrier information such as steps could be determined and data processing was easy as a base for providing various features.
