Abstract
Because road tunnel inspection manual was revised in June, 2014, the periodic inspection once in five years was required. There are many road tunnels of 11,000 in Japan, development of inspection technology, and securing of talented person becomes important. As an inspection robot technology, MIMM (Mobile Imaging Technology System & Mobile Mapping System) attracts attention now. In this research, we weighed MIMM measurement result against a proximity viewing result in a real tunnel and carried out the quality inspection of the crack.
