the result of Fountain is normal
butbut thethe result of the Herzjesu and southbuilding's dense points is too small...
Please give me some advice.
This is strange. Can you please post an image of the sparse model as returned by colmap? I suspect the poses are somehow wrong. I haven't evaluted D2 recently on these datasets so I am not sure where the issue might be coming from.
Also did you try other methods, e.g. SIFT, to make sure the data for these scenes is not corrupted?
Hi mihaidusmanu, Thank you for your reply. Can you give ,me the results of three datasets run on D2-Net? I can't reproduce them for the moment.
the sparse model result of foutain.
the sparse model result of herzjesu.
I can't tell the difference between them.
Hi mihaidusmanu,
I sorry.I found my mistake. I forgot to delete the previous reconstruction results, resulting in the dense reconstruction results that remain unchanged. Now other results are normal, that is, there is still a big difference between the mean track length and other methods.The paper uses the mean track length value as the track length or other values?
Hello. A shorter track length is normal. D2-Net has a lot of features (sometimes clustered together) and that ends up splitting longer tracks into multiple shorter ones. The following paper also reports similar results: https://arxiv.org/pdf/2003.08348.pdf
