2012-10-18 04:26:29 -0600 | asked a question | findFundamentalMat + RANSAC = strange behavior Hi I have synthetic data for features. these is absolutely correct. I can check that. So I have 10 features correspondences for cv::findFundamentalMat and I use CV_FM_RANSAC. openCV always kicks points out of this set and finds a completely wrong fundamental Matrix. The Strange thing is, 7 correspondences are left. But the RANSAC in findFundamentalMat uses the 8Point algorithm as far as i know. So i have no clue whats going on here. I also have the features in 3D and use solvePNPRansac. Everything is fine there. Even when i change the coordinates of my features, the function findFundamentalMat just kicks some other 3 corespondences. When i use the CV_FM_8POINT method the results are fine. But i have to use RANSAC because normally i have douzens of noisy features. Anyone any idea? |
