Restoring Notre-Dame through cutting-edge technology: The role of 3D scanning in the cathedral's renovation
In a groundbreaking move, Paris has unveiled the restoration of Notre-Dame Cathedral after a five-year refit, with the help of advanced technology. The strategic placement of high-precision 3D scanners, drones, and other imaging tools has allowed for a quick and thorough survey of Notre-Dame's structure, following the devastating fire that occurred in 2019 [1].
The fire marked a tragic moment for one of the world's most beloved Gothic landmarks, causing extensive damage to its interior. However, the global outpouring of grief and an urgent commitment to rebuild Notre-Dame sparked a mission to restore it to its former glory [2].
The digital archive created using these scanners serves as a crucial part of this mission. Over 2,000 scanning positions were meticulously recorded during several survey campaigns, capturing every detail of Notre-Dame's exterior, interior, and roof [3]. Mexican architect Alejandro Arredondo of AGP is one of the experts responsible for 3D modeling of Notre-Dame.
The virtual twin of Notre-Dame Cathedral was created by combining these detailed images and scans. High-resolution cameras, lasers, and AI algorithms were used to stitch the collected data together into a precise, fully digital 3D replica of the cathedral [1].
The resulting digital twin serves as a permanent, highly accurate record of Notre-Dame’s structure, story, and symbolism. It enables preservationists to study and maintain the cathedral virtually, and allows for immersive virtual visitor experiences [1][3][4].
Moreover, the digital twin is aimed at safeguarding Notre-Dame's legacy after the significant architectural tragedy. By meticulously documenting the entire monument, these tools are enabling more precise restoration work [3].
The digital archive is also informing the ongoing restoration of Notre-Dame. Specifically, AI was employed not just to construct the 3D model, but also to help detect potential current structural issues from the scanned data, aiming to assist future preservation and maintenance efforts [2].
With this digital twin, the future of Notre-Dame's conservation efforts is looking promising. The digital archive ensures that Notre-Dame's architectural and historical details are preserved for future generations, potentially preventing the kind of prolonged restoration effort that followed the 2019 fire [1][2].
