Conventionally, when damage was detected, the spot was manually described in the drawing. Problems were frequently overlooked and aging deterioration could not be easily compared. Also, traffic control was required.

Obtained 1 mm/pix of high-resolution color images without traffic control while driving at a high speed of 100 km/h. Extracted cracks from captured images and outputted them in report format. Not only cracks but the condition of structures in the tunnel could be checked from the high-resolution images.
