@gfiameni First, you need to convert RGBD to point clouds format. You may check here as reference.

from softgroup.

Yes. As long as your data has semantic_id and instance_id you can use this repo to train your data. To do that you need to create new data directory in SoftGroup/dataset/ then preprocess to generate .pth file for input and .txt file for ground truth (example here and here).

After that you can create a new dataloader in SoftGroup/data, follow scannetv2_inst.py.

Thanks a lot for your response. Do you have a specific tool for generating instance segmentation labels of the dataset? Or should I keep using Cloud Compare by adding two scalar fields to every point: semantic_id and instance_id

I just used standard public dataset. I think you can use that tool to label your data.

Thanks a lot for your reponse. Do you think that this format is valid for training. This is a sample of the txt file

Yes. This is expected format.

On the same topic, I have an annotated 2D (RGB-D) COCO datasets, is there any way I can leverage SoftGroup for 3D segmentation? Tnx
