Hi all i use opencv libraries in ros qt package . i need to use surf feature detector in my work but libraries of this function not exist in ros_opencv . i want to add external opencv libraries to package but i can't this . can anybody help me ?
You don't need external libraries for SIFT and SURF. Just add #include <opencv2/nonfree/features2d.hpp> and it will work. You initialize your fdeature detector and descriptor using : cv::Ptr<cv::FeatureDetector> detect = new cv::SurfFeatureDetector; and descriptor : cv::Ptr<cv::DescriptorExtractor> detect = new cv::SurfDescriptorExtractor; You could replace the word Surf with Sift or Orb for the feature detector. And you could also replace the descriptor with Sift or Brief.
