Four different consumer-grade cameras, two drones, 21 castle sections, 6,200 images and one software to recreate an island castle in 3D.

Our challenge: use consumer grade cameras to create a georeferenced and accurate 3D model of Switzerland’s Chillon Castle, a complex architectural structure. 6,200 aerial and terrestrial images were taken in half a day using DJI Phantom 2 Vision, GoPro Hero 3+, Canon 6D and Sony alpha 7r sensors. Images were processed with Pix4Dmapper and converted into a dense 3D point cloud of over 95 million points, digitally integrating the indoor and outdoor structures of Switzerland’s most visited historic monument.
