Query Regarding Sparse Dataset Reconstruction #14

Hello, thank you for your excellent work. I'm interested in using your model with my custom dataset. In my dataset, I have a sparse set of inputs along with their positions stored in a transform.json file. Your model also requires a folder named "sparse" containing certain files (cameras.bin, images.bin, and points3D.bin). I assume these files are generated from Colmap reconstruction. However, when I attempted reconstruction in Colmap with 8 images, I encountered a message stating "no image pairs found." I'm wondering if the steps I followed to generate the files in the "Sparse" folder are correct. If not, could you please provide guidance on how to generate these files correctly?

Thank you.

Thank you for your feedback and for sharing your experience with us! Given the difficulties you've encountered with COLMAP, we recommend adapting the dataset loader in our codebase to accommodate your existing data directly. Specifically, you can make adjustments in the following files: scene/dataset_readers.py, dataset_lora.py, and threestudio/data/loo.py. Please do not hesitate to reach out for additional support if you run into any issues.
