2013-08-18 06:28:22 -0600 | answered a question | Epilines not correct The problem with this particular scene is that almost all matched points lie on the same plane in 3d space. This is a known degenerate case for fundamental matrix estimation. Take a look these slides for explanation. I tried to increase 2nd nearest neighbor threshold in this code from 0.7 to 0.8: and got the following result: Note the corrctly matched out-of-plane background points. In general fundamental matrix estimation is very sensitive to quality of matches and number of outliers, since opencv uses 8-point algorithm for model estimation. Try to work with higher resolution images with rich textures and non-planar scenes. |
