in lightning,what's the function of the lightning_loftr.py?

[zhubingerdai]

I didn't see lightning Loftr in the paper, I don't know what lightning and Lightning_loftr are here?

Hi, the lightning is a training framework based on pytorch. Please check https://www.pytorchlightning.ai/ for more information.

[zhubingerdai]

thank you。What does geometry.py do that is also not mentioned in the article？

[zhubingerdai]

I want to ask you one more question.I read the article and looked at the code and didn't quite understand superglgly.py.I want to know in method 1/2/3/4, which method is it used, and what is its role?

[zehongs]

1. geometry.py contains basic operation of projective geometry.
2. buggy implementation.
3. the ablation study (Table 6) evaluates variants of LoFTR, not superglue.

I would like to know is Scannet data set all used for training? About 1.2 TB?This data set is hard to download。
andHave you tried running it on a 2080TI, 4GPUs? I'm a little worried about the configuration of the lab computers。。。。。

[zehongs]

I would suggest you to use the MegaDepth, which gives better depth-maps and is smaller.
You might need more GPUs, but 4 GPUs will also work.

[zhubingerdai]

ok，thank you ！
I downloaded MegaDepth

Can one gpu also work?

[zehongs]

Probably not...

[zhubingerdai]

e。。I have two questions. 1.Where is the MNN algorithm defined? Or in which module? 2.What role does warp kpts of geometry.py in supervision？

[zehongs]

1. coarse_matching.py
2. to find correspondence?

[zhubingerdai]

[zehongs]

I would suggest debugging with pdb to find if those paths of files are resolved correctly.
I think this is not a common issue, so we won't look into this. Hope you can understand!

I think I also come up with this problem, how do you solve it?

[zhubingerdai]

There is no solution. I wonder if my Undistorted_SfM file has not been downloaded completely At 2021-12-12 15:35:22, "Dongyue Li" ***@***.***> wrote: I think I also come up with this problem, how do you solve it? — You are receiving this because you authored the thread.
