Preventing corrosion from tunnel lining is an important issue in the safe operation of subways. We are developing a system that uses image recognition technology to automatically extract areas with high possibility of falling from visible image data. In the previous fiscal year, we focused on locations where there were multiple deformations on the concrete surface, but this time, for the purpose of extracting non-deformed locations and single deformation locations, high risk areas (structure, environment, etc.) Because we added a function to make a heat map by making a comprehensive judgment on the settings of) and the infrared heat measurement results, we will report.
