talnet__1203Boasting the largest number of Catholics in the world, it’s no surprise that Rio de Janeiro is home to a towering religious statue called Christ the Redeemer, which looms over Corcovado Mountain dramatically in the grey mist and weather. It’s most certainly a landmark worthy of quality replicas, but due to its size, geographical area, and general weather conditions, no one has been able to employ a scanner up to the massive task for compiling data of the statue in order to make something besides a rudimentary replica by hand.

Drones are making many tasks easier these days though, and are not just relegated to military operations anymore, as evidenced in this project taken on by Pix4D, Aeryon Labs Inc., and Pontifical Catholic University of Rio de Janeiro. Pix4D is able to provide processing of images and data as their software a3dstatue_corcovado_thumbutomatically translates terrestrial and aerial imagery photographed by the drone.

Aeryon Small Unmanned Aerial Systems provides exactly what their name describes in the form of drones that can be flown by anyone, in any conditions, controlled by a computer. While military uses abound for these products, they are also used by other civilian businesses as well as the public safety sector.

Aeryon products are known for their user friendliness and integrate with standard data processing software. They provide reliable data and can handle very rough weather. In the military, soldiers often use them for compound protection. Commercial uses are many — from surveying to agricultural needs to infrastructure inspections and even wildlife monitoring. Easily transported, the drones can be carried from point A to point B and can be in the air in a matter of minutes, and were the perfect solution for gathering images of the statue.

b126d9be4e420364Teaming up with the University, the goal was to collect enough data to make a high-quality 3D model of the Christ the Redeemer statue, which stands 38 x 28 meters (roughly 124 x 91 feet). They endeavored to obtain their data on six mornings, working around a number of factors such as unpredictable weather, restricted hours, and difficult lighting conditions. After some effort, they were able to get 3,584 images over a span of 19 flights which lasted 10 minutes each.

Dividing the statue and the project into three sectors — the statue, base, and surrounding area — and nine subsectors, they were able to collect the data while challenged with reflection, background images, and issues regarding scale.562f6650f503fae0

All of the images were processed using Pix4Dmapper Pro desktop software, with the resulting 3D model being a compilation of 134.4 million points, and as a full 3D textured mesh of 2.5 million triangles. The replica will be used and presented by the University for upcoming projects in the near future. The completed 3D digital model also opens the door to the potential to 3D print an exact replica of the famous statue.

Have you seen this statue in person? What do you think of the impact drones will have on being able to make other replicas of statues and sites in hard-to-reach areas? Tell us your thoughts in the Christ the Redeemer 3D Scan forum over at 3DPB.com. Check out the video below describing the project.
