In order to improve the efficiency of bridge inspection using inspection robots, the functions of software using 3D models were considered from the following five points.
1. Creating a 3D model (point cloud model) of a bridge
2. Visualization of image shooting position and shooting direction
3. Visualization of image position by overlaying 3D model and image
4. Grasping of deformation status and display of deformation position on 3D model
5. Associating and storing images and deformations based on the 3D model
