exact format of occlusion linemod for hybridpose

[monajalal]

I have this from PVNET:

(hybridpose) mona@ada:~/HybridPose/data$ ls /data2/data/BOP/OCCLUSION_LINEMOD

Since, I couldn't download occlusion linemod using your script:

could you show how you exactly want the occlusion linemod to be formatted?

    os.system('for i in $( ls data/occlusion_linemod/models | grep [A-Z] ); do mv -i data/occlusion_linemod/models/"$i" data/occlusion_linemod/models/"`echo $i | tr \'A-Z\' \'a-z\'`"; done')
    os.system('for i in $( ls data/occlusion_linemod/poses | grep [A-Z] ); do mv -i data/occlusion_linemod/poses/"$i" data/occlusion_linemod/poses/"`echo $i | tr \'A-Z\' \'a-z\'`"; done')

Is it just you wanna lower case the name OCCLUSION_LINEMOD? any explanation or $ls on folder name is helpful

This is what I have for linemod itself:

Hi Mona,

Thanks for your question!

The old version of the Occlusion Linemod dataset has been taken down from the download website. As a result, this repository no longer supports the Occlusion Linemod dataset. Simply using the PVNet data or the new BOP data will probably not work.

I would suggest you take a very close look at lib/datasets/occlusion_linemod.py, understand the logic, and try to write a new PyTorch Dataset class that loads the new Occlusion Linemod data. In the existing file, there are some transformations to align the Occlusion Linemod labels with the Lindmod labels. Depending on how the new labels are constructed, you may or may not need these transformations.

Unfortunately, I do not have the capacity to help you with this at the moment. My suggestion is to seek help from an experienced person in your organization who is familiar with 3D geometry and debugging. I hope this helps! Let me know if you have further concerns.
