Wrong in using solvePnPRansac in opencv 3.3.0.

asked 2017-08-22 05:20:43 -0500

When I use solvePnPRansac function to do pose estimation for KITTI datasets: solvePnPRansac(pts_obj,pts_img,cameraMatrix,Mat(),rvec,tvec,false,100); The rvec and tvec is wrong after a while. But I use solvePnPRansac function in opencv 3.2.0, it works well.

Can you add the data when it failed to be able to reproduce the issue?

I download from here: http://www.cvlibs.net/datasets/kitti/.... I use the sequences 00. Meanwhile,I use SIFT and FLANN.

The easiest thing to debug would be to upload somewhere the values of pts_obj, pts_img and cameraMatrix when it fails in 3.3 and works in 3.2.

Also, can you show the values rvec and tvec in 3.3 and 3.2?

The only difference in solvePnPRansac between 3.3 and 3.2 should be that in 3.3 the final camera pose is estimated using all the inliers + some minor changes as described here.

I am meeting the same problem, version3.3 produces the wrong results, how to solve it?
