OpenCV图像匹配算法之surf详解编程语言

SurfFeatureDetector surf_detector(minHessian) ; SurfDescriptorExtractor surf_descriptor ; vector KeyPoint kpts1_surf, kpts2_surf; Mat desc1_surf, desc2_surf; Ptr cv::DescriptorMatcher matcher_l2 = DescriptorMatcher::create("BruteForce"); //欧氏距离匹配 vector vector DMatch dmatches_surf; vector Point2f matches_surf, inliers_surf; surf_detector.detect(img1,kpts1_surf); surf_detector.detect(img2,kpts2_surf); info.n1 = kpts1_surf.size(); info.n2 = kpts2_surf.size(); surf_descriptor.compute(img1,kpts1_surf,desc1_surf); surf_descriptor.compute(img2,kpts2_surf,desc2_surf); matcher_l2- knnMatch(desc1_surf,desc2_surf,dmatches_surf,2); matches2points_nndr(kpts1_surf,kpts2_surf,dmatches_surf,matches_surf,DRATIO); info.m=matches_surf.size()/2; compute_inliers_ransac(matches_surf,inliers_surf,MIN_H_ERROR,false); info.rm=inliers_surf.size()/2; t2=cvGetTickCount(); info.t=(t2-t1)/1000000.0/cvGetTickFrequency(); Mat img1_rgb_surf = imread(path1,1); Mat img2_rgb_surf = imread(path2,1); Mat img_com_surf = Mat(Size(img1.cols*2,img1.rows),CV_8UC3); if(show == true) draw_inliers(img1_rgb_surf,img2_rgb_surf,img_com_surf,inliers_surf,2); imshow("surf",img_com_surf); waitKey(0); return; }

使用

 INFO surf_info; 

 surf(path1,path2,surf_info,false); 

 showInfo(surf_info);
