How to get the raw data into Colmap format to use 3DGaussian?

Open meidachen opened this issue 2 years ago • 1 comments

Thanks for releasing the converter code for NGP, I'm wondering if is there a converter for getting the raw data into the colmap format for 3D Gassian? I'm trying to create one, but was having issues with getting the camera poses aligned with the provided point cloud. I was using the inverse of the alignmentTransform to trans the point cloud to the camera coordinate, but the result looks like this in Colmap, could you please help? Capture

I also met the same issue. I found the aligmentTransform looks so wired and it might wrong.
