I'm trying to implement a flann based matcher and use it with ORB. How can get it in OpenCV? Now I'm using brute force hamming matching. If I undestood well, LSH has better performance related to Brute force matching. Is it right?

http://answers.opencv.org/question/924/lsh-matching-very-slow/ shows you how to use it. And no, it is not better than brute-force - but faster if you have a sufficient large data set.
