Shinkansen tunnel lining inspection
with Mitsui E&S Machinery Co., Ltd.

Our client’s problem

Application of AI to radar exploration technology, cutting the time required for image analysis by 75%

Mitsui E&S Machinery Co., Ltd.

Recently, aging social infrastructure has become a problem, and plans to extend the service life of infrastructure facilities are being promoted nationwide.
As the need for inspection and maintenance to extend service life increases, there is a need for technology to support the shortage of engineers.

Benefits

The process of inspecting tunnel lining concrete by analyzing images used to take four days.
But by applying technology that automatically detects the presence of abnormalities,
the process was shortened by 75% to only one day.

In addition, our software prevented omissions that were previously prevented by having engineers double-check each other’s work, thereby improving work efficiency and accuracy.
“By automatically detecting anomalies from 3D radar images, we have been able to support engineers and improve the speed and quality of the process. In the future, we plan to deploy this technology in radar exploration for roads and bridges. We will continue to develop inspection technologies that can improve the efficiency of investigations, inspections, and maintenance. We will also propose advanced inspection services to meet customer needs and increase customer satisfaction.”
