Have you ever wondered how the ‘Christ the Redeemer statue in Rio de Janeiro was constructed? The iconic landmark measures 98 feet tall and spans a gigantic 92 feet wide, making it one of the contemporary world’s seven wonders. Now, thanks to these geospatial mapping specialists geoSLAM’s laser scans, we can observe the remarkable structure like never before. Before the statue’s 90th birthday restoration work began, ego slam was asked to construct a digital twin.
Scanning The Statue: Christ the Redeemer
The public was barred from summit of Mount Corcovado, where Christ the Redeemer stands, while entire site was searched – inside and out. You’d think that scanning such a detailed image would take a long time, yet it only took 45 minutes, thanks to the newest SLAM (simultaneous localization and mapping) and UAV technology. Over 180 million data points were collected, resulting in a detailed digital representation of the massive monument.
Using a compact handheld 3D scanner, Gabriel de Barros praxedes, geoSLAM’s Latin America channel manager, explored the steep staircases and tight tunnels of Christ the Redeemer’s construction to take the inside images. The same handheld laser scanner was then installed on a drone to capture the monument’s detailed exterior. Gabriel analyzed the data fast to see the scan’s results before leaving the site, double-checking that he’d accurately caught every information. On the internet, a complete 3D representation of the data can be viewed and changed. Given the amount of detail on the monument – from the face, hands, and robe, to stairs within and carved marble base beneath it, I’m in awe of the capabilities of this technology and the clarity of data produced,’ Gabriel said of the project. As a result, we could catch the statue in a unique light, which nearly no one has ever seen before.
Christ the Redeemer: Symbol of Brazlians
Christ the Redeemer statue is one of the most iconic sculptures on the globe and a symbol of optimism for many Brazilians both near and far, and I’m glad I was able to photograph it in its current state before restoration work begins. It’s hard to imagine this statue is nearly 90 years old; the scan reveals the extent of the detail.
