Technological Development of Video Capture on the Maintenance Stage for the Concrete Lining of Horizontal Tunnel
For the sustainable use, we must do the suitable maintenance to the lining of the tunnels. Now in Japan, many administrators of road, railway, subway, hydro, energy supply tunnels adopt the video capture system and crack detection system. Several video capture systems for the highway roads in Japan are track car mount and they can get the clear pictures of concrete linings on 80km/hr driving. And several developers have conducted practical trial AI solution system to find the crack of lining with these pictures. Our system can be loaded on the maintenance incline cable car or the shaft bucket by the unit of light-weighted and small sized and we can take the clear pictures of inclined tunnels and shafts linings practically.
