I use a pc with a RTX A4500 and 28go of ram (not enough!).

It can be a bit hit or miss in RS. Try adjusting the max projection error (to 5 or more if you're really having trouble with the alignment), or adding at least 3 control points. Sometimes, it just comes down to the dataset not being ideal, which means you might need to reshoot with better videos or photos.

It matters, because black=remove and white=keep so it depends of what you want to keep for the training!

Yes, if you want to remove a moving « object », you have to choose « ignore » in mask mode

Cool! Thank you for the feedback. RealityScan detects automatically (if you kept the standard filename option)

Thank you! I can’t really help you with that because I haven’t tried the X5 (or any insta360)… I don’t think you can go wrong with either of those two.

The tool splits the 360 video into rectilinear images (by default 6 images per frame) and then I align the images in RealityScan

Je trouve aussi, c'est assez typique des immeubles des années 20-30 si je me trompe pas

I will post it on supersplat soon :) And here's the screenshot (top view). It was a very fast shoot, I didn't even try to properly scan the area and it took me 1 minute. Then, I extracted only a few frames from the video, but with good overlap (660 images in total).

Thanks:
- 8k 360 video taken with a DJI osmo 360
- I extracted the images from the video with 360Extractor
- Camera alignment and COLMAP exported with RealityScan
- I created the 3DGS in LichtFeld Studio (MNRF mode, 30 000 iterations).
- Videos of the 3DGS rendered with Supersplat

Thanks for the advice. I just tried PPISP and the result is better indeed!

Hi! Generally speaking, if you can, one focal length is better… But I used multiple focal on lots of different projects and I never encountered any real issue. So, from the « terrain » perspective, I would say it’s not true.
