Spatial Clearance Verification Using 3D Laser Range Scanner and Augmented Reality
A spatial clearance verification system for supporting nuclear power plant dismantling work was developed and evaluated by a subjective evaluation. The system employs a three-dimensional laser range scanner to obtain three-dimensional surface models of work environment and dismantling targets. The system also employs Augmented Reality to allow field workers to perform simulation of transportation and temporal placement of dismantling targets using the obtained models to verify spatial clearance in actual work environments. The developed system was evaluated by field workers. The results show that the system is acceptable and useful to confirm that dismantling targets can be transported through narrow passages and can be placed in limited temporal workspaces. It was also found that the extension of the system is desirable to make it possible for multiple workers to use the system simultaneously to share the image of the dismantling work.
