What are best practises to use equirectangular image frames from a 360 video as input?

[Bardo-Konrad]

My approach

Use aliceVision_split360Images.exe --splitMode equirectangular --equirectangularNbSplits 8 --equirectangularSplitResolution 768 --fov 90.0

Result is random. Some datasets are found using exhaustive matching, many others are not.

Using it in meshroom works for some reason, but meshroom does not export to colmap for further processing.

I have implemented panoramic camera sfm in colmap，https://github.com/lambdald/colmap which may be helpful to you

You can try our repo https://github.com/json87/SphereSfM

@json87 Your repo creates files gaussian splatting cannot handle as it doesn't have the appropriate lens.

I think you should modify the code of GS to support spherical images.
