Drone maps Christ the Redeemer in 3d to create first ever accurate replica

The giant-sized Christ the Redeemer statue in Brazil has been recently mapped by a drone in 3D to create its first ever accurate replica. The mapping was a part of a collaborative project between the PUC University of Rio de Janeiro, 3D-scanning company Pix4D, and Canadian drone makers Aeryon, the Verge reported.

Data was collected over a series of 19 ten-minute flights by one of Aeryon's quadcopters, with 2,090 separate images stitched together to create the final 3D model. This now exists as both a wireframe mesh made up of 2.5 million triangles and a point cloud composed of 134.4 million individual points, more than enough for an accurate record of the statue.
