Hi,

stitcher = Stitcher::createDefault(true); Mat pano; vector<mat> imgs; imgs.push_back(img1); imgs.push_back(img2);

stitcher.stitch(imgs, pano);

Last line throws error:

OpenCV Error: Assertion failed (func != 0) in knnMatchSingle, file /home/hyper/Downloads/opencv-3.0.0-beta/modules/cudafeatures2d/src/brute_force_matcher.cpp, line 503 terminate called after throwing an instance of 'cv::Exception' what(): /home/hyper/Downloads/opencv-3.0.0-beta/modules/cudafeatures2d/src/brute_force_matcher.cpp:503: error: (-215) func != 0 in function knnMatchSingle

Stitching without GPU - OK.

Any ideas?

Thank you.

If i use FeaturesMatcher without CUDA, then no error:

Ptr<detail::featuresmatcher> featuresMatcher = makePtr<detail::bestof2nearestmatcher>(false, 0.65f); stitcher.setFeaturesMatcher(featuresMatcher);

But stitch with CUDA not faster than without CUDA in opencv 3.0 beta. Also default blender/seamfinder with CUDA not good.
