Fujitsu Limited and Fujitsu Advanced Engineering Limited recently announced that they have successfully completed the field trial that was being performed using image processing technology to recognize the stone blocks positions prior collapsing of walls in earthquake.

The walls of Kumamoto Castle were damaged completely in the Kumamoto Earthquake in 2016. The field trial took place for approx. a month in November 2018. Fujitsu confirms that usage of this technology brings down the total duration of time needed for the process delivering an accuracy rate exceeding 80%.
This field trial has helped Fujitsu develop an identification system that pinpoints the stone positions through high-speed partial image search technology. The technology matches a given image among hundreds and thousands of images even if the former shows just a part of complete image.
Fujitsu fused this technology with an image optimization technology that further improved the precision of search results. The combination of these two techniques then proved its worth when it helped in matching the collapsed stones images of the still intact stone walls before their collapse. It was a huge saviour on grounds of precision and search time. The final results gained from it helped the team identify correct stone locations for walls restoration in their original positioning with an accuracy exceeding 80%.
