At 6:50 p.m. local time on April 15, Notre Dame was seriously damaged in the fire, which the world deplores. But what's the latest news about Notre Dame laser modeling? Can Notre Dame be rebuilt?
In 1831, Notre Dame, which had been standing for more than 600 years, was in disrepair and the authorities decided to demolish it. That year, Victor Hugo's novel Notre Dame saved it, and Hugo launched a fund-raising campaign to restore the church.
In 1843, Notre Dame de Paris experienced creative restoration in the hands of the architect Viola & middot; Le & middot; Duke. During World War II, it escaped Hitler's frantic questioning: "is Paris burned?"? It survived along with Paris, and by 2019, it had another dark moment.
At 6:50 p.m. local time on April 15, Notre Dame was seriously damaged in the fire, which the world deplores.
Fortunately, someone has done a great thing - to build a three-dimensional model archive for Notre Dame. This may contribute to the post disaster restoration and reconstruction of this human civilization.
This person is Mr. Andrew Tallon. He was an associate professor of architecture and art history at Vassar College in the United States. He was also the first expert in the world to lead a team to scan the panorama and internal structure of Notre Dame. In 2015, he scanned Notre Dame with a laser beam and obtained its three-dimensional model.
In July 2015, National Geographic magazine reported how Talon used laser scanning technology to record the whole picture of this gothic cathedral very accurately.
In the past few years, Talon used laser scanners to scan more than 50 locations inside and outside Notre Dame to collect data, detailing every detail inside the church.
He scanned every part of the church with a laser beam, measuring the distance between the scanner and the laser hitting the building structure. Each measurement result is represented by a light spot. After the collection, he put billions of light points in the three-dimensional image, which can be accurate to 5mm, drew lines, combined with the panoramic photos taken on the spot, colored the elevation in the image, and finally added the light and shadow effect to build a very realistic and accurate three-dimensional model.
Talon once said, "when I recreate the building with laser scanning, I feel like the child staring at Notre Dame. I did, and I was able to get into those buildings, including the top of the roof, the top of the vault, the interior of the stairwell, and all the hidden spaces that people usually don't see, which is the most exciting.
