How can i get the brisk's orientation?

edit savecancel

Thanks! Could you give me an example about how i do this in c++? I've already tried using "keypoint.angle" but it doesn't work. EDIT I mean, I just add the "types.hpp" in my code, but I still can't use it on my keypoints that I've extracted before with the BRISK constructor.

You need to add the whole OpenCV library, not types.hpp alone ... when creating a vector<Keyoints> collection; and then filling it with data by calculating keypoints, you can loop over them and access the angles using collection[i].angle which I just confirmed.

Ok, thanks!

I was used points2d as keyponts... The problem is solved now, thanks!
