Realizing the power of a digital twin
In new construction, or even in as-built structures, it is straightforward to do a site visit – but in situations as complex as this, that’s not always an accessible option. To document difficult areas in a building takes time, personnel costs and can even have potential safety concerns. In addition, it can be hard to inspect areas that don’t have corresponding photos or drawings or to find the right photo. Creating a 3D digital twin, however, can make repeated site visits less necessary, and put visuals into a more comprehensive view for better understanding.
Indeed, the data captured with the NavVis mobile mapping system helped to compile the damage reports. Above all, a digital twin of the castle keep before the 2016 earthquake might have made the restoration more efficient, Mr. Kakuta (KKE), reflected.
“With NavVis VLX, it is possible to quickly measure indoor and outdoor areas of large-scale historical buildings, and by displaying the obtained data in NavVis IndoorViewer, it is possible to understand 3D shapes with point clouds, and to check materials and colors in detail with panoramic photos, and to share, instruct, and report data anytime and anywhere. And with NavVis IVION, innovative new features such as multi-site and cloud processing can increase the efficiency of these mapping and display tasks many times over.”
For the Chief Examiner of Kumamoto Castle, this new process has inspired them to find even more applications for NavVis reality capture.
“In the future, we hope that NavVis can be used not only for the restoration of Kumamoto Castle, but also for other important cultural properties in Kumamoto Prefecture and the country. If we can accumulate the history of restoration, maintenance management, we will be more efficient, which will lead to longer service life and cost reduction,” said Mr. Tashiro.
