Advances in ``3D scanning and preservation technology for heritage sites'' that can also be used to protect cultural properties
In recent years, it has been reported that relatively new technologies such as drones, 3D printers, and private satellite internet are being used in wars, but another breakthrough technology, 3D scanning, is said to be contributing to the acceleration of wars. It is used to alleviate the destruction of cultural properties caused by war. VR researcher Aaron Frank explained the advances in technology that scans real objects and converts them into digital ones.
A Revolution in Computer Graphics Is Bringing 3D Reality Capture to the Masses
According to France-based UNESCO (United Nations Educational, Scientific and Cultural Organization), from February 24, 2022, when Russia began its invasion of Ukraine, culturally important facilities such as religious and historical buildings in Ukraine It is said that 327 buildings have been destroyed .
In order to alleviate the impact of cultural loss due to the destruction of buildings due to war, several researchers have been working on a project to scan buildings and create 3D models. . However, until a few years ago, the scanning itself required expensive tools and software, so protection efforts were slow.
Later, as technology progressed, a remote sensing technology called '
Not only Apple, but Google also announced a 3D data synthesis technology called ` `Neural Radiance Field (NeRF)' ', making it possible to construct spatial data from just a few images. Google uses this technology in Immersive View , a 3D version of Google Maps, which is useful for providing directions and information display using AR.
With the advent of these technologies, anyone can now use a smartphone to create Hollywood-quality 3D assets that, until recently, could only be created by well-equipped production teams. Denmark's UNESCO National Commission and others are conducting a volunteer activity called `
Backup Ukraine is a project by UNESCO and others that calls for cooperation from people living in Ukraine. Ukrainian people photograph heritage sites and monuments, tag them, and publish them on the site, making it possible for people all over the world to see the objects that exist in Ukraine and their locations.
Each object that people have saved can be viewed 360 degrees.
According to Bilawal Sidhu, a former Google product manager who worked on 3D mapping, the work in Ukraine is an outstanding example of the astonishing speed of progress in 3D capture and graphics technology. Mr. Sidhu expressed his surprise by saying, ``The speed at which capture technology is getting into people's hands is exponential. You can do it all with an iPhone in your pocket.''
Mr. Sidhu pointed out, ``There is technology that allows users to walk around anywhere on the earth and experience what is happening there immersively in real time using VR.'' Although it is not known when it will be implemented, it seems that if it is realized, it will be greatly useful for teleportation, remote conferencing, and communication using avatars.
