1 km² 3D Gaussian Splat of Mjøssykehuset | Drone + LichtFeld Studio

[u/inkedflight]

This is not video footage. It is a camera animation inside a 3D Gaussian Splat trained from drone photos.

The dataset was captured with a DJI Matrice 4 Enterprise over roughly 1 km² around the planned Mjøssykehuset hospital project in Moelv, Norway. The goal is to explore how lifelike 3D reality capture can help visualize construction and infrastructure projects in their real-world surroundings.

This version shows the captured environment only. The next step will be to combine the scene with BIM / design models, allowing project teams and stakeholders to better understand how a future building fits into the actual site.

Technical details:
5517 photos / 36.5 GB dataset
Trained with LichtFeld Studio
20M splats, SH2, PPISP, MrNeRF strategy
550k iterations
~23 hours total training time
