ducha-aiki / pymagsac Goto Github PK

Hi @ducha-aiki - I just thought I'd let you know that the author of the MAGSAC algorithm licensed his repository under the GPL this morning (https://github.com/danini/magsac/blob/master/LICENSE), so you'll need to update this repository to reflect the GPL as well - this codebase can't be licensed under MIT and anyone who uses this would mistakenly violate his license!

Is there a way to estimate Essential Matrix using DefaultEssentialMatrixEstimator() for cameras which don't have camera intrinsic matrices (for eg, 360 degree cameras)

I find pymagsac will be stuck sometimes, it can run tens of minutes and do not stop even when just 40 points. Here is an example.

import numpy as np
import pymagsac

data = np.load('test_data.npz')
for idx in range(100):
    print(idx)
    F, mask = pymagsac.findFundamentalMatrix(data['p1'], data['p2'], 3.0)

I am able to compile zjhthu's pymagsac: https://github.com/zjhthu/pymagsac, but failed with this version. The title shows one of the errors. I am not sure whether it is due to this version incorporating magsac++, which might cause problems somewhere.

Hi. What does this file "img/graf_model.txt" store?

Hi,

Thank you for the bindings, they're very useful.

Is there any reason why in your implementation the minimum number of samples required for homography estimation is 7, as written here, and not 4?

I tried changing the line to 4 and rebuilt it, but the method started to return None, so I assume there are more changes required.

Hi @ducha-aiki
Thanks for your great work and sharing.
I tried your code on d2-net matching test.
I noticed the Homography results are different even I ran the same data in the same parameters(I mean the same threshold)
which the fluctuations can not be ignored.
Could you give me some suggestions to get a stable result?

python3 ./setup.py install

After executing the above command, the following error appears

This is an amazing repo. Great work!
I wish to know if this is also includes the author's latest MAGSAC++ or if it is just MAGSAC.
Also, is there a way to use this to find the essential matrix?
Thanks
