Multiway registration module taking forever in Open3D implementation

[preethamam]

I followed your "Section 5.2. Multiway Registration" details and I implemented DGR as the pairwise registration module in Open3D multiway registration example. When I tested on the Indoor LIDAR dataset (e.g. bedroom) it is taking forever for pairwise registration due to 220 fragments. Also, for many examples in the dataset, when I use the first few (6 nos.) fragments, the registration is bad.

How long did it take for your implementation?

Could you please share the multiway registration module that you used for your paper?

hi,did you download the pretrained models?the urls seem broken.Hope you can send these pretrained models to me.

Hi @preethamam can you please share your modified multiway registration script?

Thank you!

@preethamam @pranavgundewar Hey, I am working with the 3D match dataset in DGR. But I don't understand the text file format they use for the input. eg:
7-scenes-chess@seq-01_000.npz 7-scenes-chess@seq-01_001.npz 0.886878

I can see the first two variables are the names of the clouds. I don't understand the context of 0.886878 here. I doubt if its intensity. Can you please let me know if you can? Thank you in advance.
