A drone primarily reminds us of the flying object with camera mainly used by the militants. Unnamed aerial vehicle normally ruffled to as a drone is a flying remove controlled machine. Apart from military being the only ones using drones many creative makers and engineers have been using drones for different purposes than war. A wild life photographer has set a new example of sing a drone for an extremely distinct purpose. He used a drone along with a camera and a 3D modeling software. The photographer very creatively used the drone technology and the photogrammetry techniques to great a 3D model of a huge Peruvian statue of Christ.
The statue stands 122 feet tall and is located in Lima, Peru which is known as the “Christo del Pacifico” or "Christ of the Pacific". It is also known to be one of the highest statues of Christ. There are many controversies related to the statue like for many it is a rip-off of the famous Brazilian statue of Jesus, "the Christ of Corcovado". Whereas some architects feel that te status violates the building codes. Inspite of all these controversies the statue still stands as an inspiration to many.
It inspired a wildlife n photographer Jeff Cremer and he decided to unveil his DJI Phantom 3 Pro drone skills with the help of this statue. Hundreds of photos are takes to make an accurate 3D scans of the statue. Also Sculpteo has provided a tutorial with how to create your own drone.
Cremer used the drones "point of interest" setting; he set the centre of the statue at the top of its head and later shifted the drone 82 feet back. Every 2 or 3 seconds the drone’s camera would click picture, clicking a half full of 30 to 40 photos in one circular motion around the statue. Further Cremer recommends an overcast of cloudy day to ensure the consistency of lights. Drone cameras may have a problem of blurred of images but h4 had explained Sculpteo how the blurring problem be reduced.
“To reduce the blur that can occur in photos when using a drone make sure to check if your camera will allow you to turn off the image stabilization, if that cannot be done try to change your shutter speed to something like 1/1000th of a second to reduce the “noise” which causes the blurring effect.”
A phoyogrammetry requires more than one humdred quality photos. Once Cremer had more than 100 quality photos, using the Altizure program he generated a 3D map from drone photos. Cremer used Autodesk Momento to upload his images to the cloud server. And used Momentos slice tool to get the statues cutout from the photos from the top to the base. Autodesk 123D Catch or a combination of Meshmixer and MeshLab can b4 used as a substitute of Altizure.
Last but not the least the final step was to 3D print the statue using Sculpteo, “I chose Sculpteo because I saw that they had full color printing available. I also liked that their website does automatic analysis and repair of the uploaded files to make sure that the model prints ok. Shapeways.com or other services may have these options but Sculpteo looked the easiest.”
Jeff Cremer is all set to enjoy the feel of the mini 3D printed replica ”Christ of the Pacific” in his own house. 3D prints will inspire more people to come forward and experiment with new technology like Jeff Cremer.
