How to Generate sfm_scene.json for other Dataset

[irisfreesiri]

I would like to use a different dataset from the following link: Gaussian Grouping - Figurines. However, I encountered an issue and would appreciate some help.

The structure of the dataset is shown in the image below, and it does not contain an sfm_scene.json file. Does anyone know how to generate this file?

Thank you very much for your assistance!

I got the same quesions.
After running run_pre.sh.
I got cam and pair.txt. I wonder how can I make these to sfm_scene.json?

I got the same question, can you give me a code to convert a colmap form data (images.txt, cameras.txt, points3D.txt) into the DTU's sfm_scene.json?
