GPS Reconstruction

[LordMaddhi]

hi guys,

I tried to use the "from_gps" option in SfMTransform. My images are taken with my phone with a RTK GNSS receiver and Ntrip, so i got centimeter accurate GPS coordinates. The point cloud looks very accurate as you see here:

But the result after Texturing is very scuffed:

Are there some settings i have to use in the other nodes for the gps mode to get a good model out of it? or is there a good example pipeline for GPS reconstruction?

I tried a bit and activated "consistent scale" in DepthMap SGM and Refine. Now i got a better model, but also not perfect (holes in the stree etc):

I dont really know what i should tweak next... 😅

Could could try keeping the default pipeline intact, then add the SfMTransform node, then use the SfMAlignment node to align the default reconstruction by your oriented and scaled transformation?

that worked! thank you :)

but i dont really get what the difference is between using SfmAlignment and adding a second SfmTransform with auto_from_cameras
