Our image analysis technology, which utilizes Artificial Intelligence (AI), helps engineers detect cracks on bridges,
tunnels and other vital infrastructure, saving them valuable time and energy.
Over time, Japan’s bridges, tunnels and other infrastructure have aged. To ensure safety, the national and municipal
governments have mandated regular close visual inspections of all social infrastructure. However, there are just too
many structures for the current number of engineers to inspect. To date, infrastructure inspections have required
advanced technologies, experienced and skilled engineers to inspect each structure by eye, and indicate each crack by
chalking a line by the side of it. They were then required to sketch each crack or fissure, trace the entire image,
then make digital images and include them in reports.
As there is such a large number of sites to inspect, and given the amount of time required for inspections due to a
lack of skilled engineers, making the process more efficient has become a pressing issue. To resolve this social issue,
we developed an image analysis service that utilizes AI.
We have applied our existing medical image analysis technology, which automatically extracts parts of blood vessel from
images, to the detection and visualization of cracks in structures. This development made it necessary to train a
computer to learn from vast amounts of image data in order to accurately detect chalking and cracks in structures. So
we traveled to sites across Japan, listened to the views of inspection companies and construction consulting companies,
collected an enormous amount of images and data of cracks, and continued developing our technology.
This resulted in the creation of our Social Infrastructure Image Analysis Service, which can be used easily by anyone.
This service has reduced the required amount of time for inspections by half, and is playing a vital role in supporting
inspection engineers nationwide.
We will never stop developing and further evolving the technologies we originally created for the photographic field to
make the world a safer place!
