抄録

The public facilities needing repair increases every year in Japan. Particularly, moorings of port facility under severe natural environments coming in contact with seawater surface needs appropriate maintenance. Nowadays, various studies are being conducted using ICT and robots to solve social problems. Therefore, the authors have verified the applicability of the inspection work on the undersurface of the upper pier concrete using images acquired by unmanned surface vehicle. This paper describes the process and results of deformation measurements and judgments such as cracks using 3D model and orthophoto mosaic image obtained by three-dimensional reconstruction process.
