Just testing the native 360 reconstruction in Colmap:
- took a random Insta360 walk video from youtube (https://www.youtube.com/watch?v=o763o9aVh5g)
- extracted ~100 full res frames using sharp-frames tool
- direct reconstruction in Colmap 4.1.1 which now supports 360 cameras (just select equirectangular camera model)
- since neither Brush nor Slang-splat support 360, went googling for a GS tool which supports equirectangular cameras, found this released 5 days ago which supports training with equirectangular camera models: Spirulae-splat (https://github.com/harry7557558/spirulae-splat)
- tested on medium settings, pretty much everything at default, 18k iterations
- no masking of people at all
