VRカメラを搭載した隧道調査支援装置の試作

抄録

In this study, a VR camera mounted simple narrow tunnel inspection device was developed to assist inspection work inside narrow culvert channels of a small hydropower plant. To reduce the burden on the waist while moving a few kilometers inside the tunnel, a commercial walking assist frame was used. Developed device was tested in a free flow tunnels with 1.5 m height in Tottori prefecture. As a result, it was confirmed that the load on the waist while walking was improved, and interval images of the fisheye camera is useful for making inspection records. In addition, we concluded the virtual inspection experience by VR goggles may be effective for sharing information to better understand the situations of the site.
