The ruins of Spiš Castle are localized in eastern Slovakia. This is one of the biggest European castles by area 41 426 m². It was included in the UNESCO list of World Heritage Sites in 1993. Spiš Castle was built in the 12th century on the site of an earlier castle.
The purpose of 3D scanning the castle was the idea to digitize an archaeological excavation and so allow to continue the research in virtual reality.
The 3D scan is combined from aerial (DJI Phantom 4 Pro) and ground-level (Sony A7r DSLR) images. Roughly 4000 pictures were shot in order to be able to reconstruct a photorealistic digital twin of the castle in RealityCapture. Umbra SceneStream is the first solution that has been able to visualize the capture without having to compromise on the output quality. Overhe4d is currently working on an even more detailed scan which we an not wait to get our hands on!
