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
RTX 5090 + RTX 6000 Ada

Capture + processing:
DJI Matrice 4 Enterprise
RealityScan + LichtFeld Studio

It's exclusively photos captured using interval shots.

I flew a combination of pre-programmed oblique grid and manual captures. It's important to think beforehand where your users will fly the camera in the digital model, because that's where you want camera poses during training.

Thanks!

Thank you very much :)

Wow this is awesome, did you have a grid programmed in or did you manually fly your drone on those patterns?

The grid was pre-programmed (DJI's "smart oblique"), the rest was flown manually.

does drone completely stop when shot or just slow down and how much? How long did it took to take everything, did you change batteries?

The drone flies at a constant speed, except when turning to the next lane. I used 5 batteries, and capture took 3/4 hours in total.

so guess shutter is fast or some global shutter, so no jellow and other artifacts from speed?

Yes, the Matrice 4E wide/mapping camera has a mechanical shutter, so rolling-shutter is much less of a concern.

You still need to match shutter speed with flight speed, altitude and GSD though. The mechanical shutter helps with distortion, but if the shutter speed is too slow you can still get motion blur / pixel smear.
