Hi everyone,

I understand that solvePNPRansac produces an inliner matrix that contains both the object points and image points.

I was wondering if there is a way to extract the two from the matrix so that I can plot the detected features in an image before and after RANSAC is applied.

Note: To plot the matched features, I use the drawMatches().

Thanks in advance!

Hi everyone,

I understand that solvePNPRansac produces an inliner both solvePNPRansac() and findHomography() produce a matrix that contains both correlated to the object points inlier and image points. outlier keypoints.

I was wondering if there is a way to extract the two from the matrix so that I can inlier points and plot the detected features in an image before and after RANSAC is applied.

Note: To plot the matched features, I use the drawMatches(). via drawKeypoints() or drawMatches().

Thanks in advance!

Is there a trivial way to correlate the position of the rows in the Mask to the list of matches and the keypoints?

Thanks in advance!

Hi everyone,

I understand that both solvePNPRansac() and findHomography() produce a matrix correlated to the inlier and outlier keypoints.

Once I was wondering if there get the Mask from the findHomography(), is a way to extract the inlier points and plot via drawKeypoints() or drawMatches().

Is there a trivial way to correlate the position of the rows in the Mask to the list of matches and the keypoints?

    for (int nextPosition = 0; nextPosition < Mask.height(); ++nextPosition) {
        if(Mask.get(nextPosition,0)[0] > 0.0){              
            inlierList_good_matches.add(List_good_matches.get(nextPosition));
                    inlierList_KeyPoints1.add(List_KeyPoints1.get(nextPosition));
            inlierList_KeyPoints2.add(List_KeyPoints2.get(nextPosition));      
        }            
    }

Thanks in advance!
