Since social infrastructure, which was intensively developed during the high economic growth period, will deteriorate all at once in the future, maintenance and management of facilities will be an issue in the future, and it is important to understand the local situation through appropriate visualization of inspection results. The authors developed a method to grasp the position, direction, and size of deformation in relation to the entire facility by pasting inspection photographs taken close to the deformed part of the sabo dam onto a 3D model of the sabo dam. There was a problem in that inspection photographs needed to be post-processed using SfM/MVS processing (hereinafter referred to as SfM processing). Therefore, in this paper, we compared a 3D model generated by a 3D reconstruction application using a mobile terminal with a 3D model generated by SfM processing, and investigated a method for importing the 3D model into GIS.
