  你能发一些代码吗？可以在名为matcher_simple.cpp的samples / cpp文件夹中找到CPU实现 . 你能跑吗？我也在OpenCV上运行了GPU版本的SURF，没有问题：

  SURF_GPU surf(1000, 4, 2, false, 0.5);
  
  // detecting keypoints & computing descriptors
  GpuMat keypoints1GPU, keypoints2GPU;
  GpuMat descriptors1GPU, descriptors2GPU;
  surf(img1, GpuMat(), keypoints1GPU, descriptors1GPU);
  surf(img2, GpuMat(), keypoints2GPU, descriptors2GPU);
  
  cout << "FOUND " << keypoints1GPU.cols << " keypoints on first image" << endl;
  cout << "FOUND " << keypoints2GPU.cols << " keypoints on second image" << endl;
  
  // matching descriptors
  BruteForceMatcher_GPU< L2<float> > matcher;
  GpuMat trainIdx, distance;
  matcher.matchSingle(descriptors1GPU, descriptors2GPU, trainIdx, distance);
  
  // downloading results
  vector<KeyPoint> keypoints1, keypoints2;
  vector<float> descriptors1, descriptors2;
  vector<DMatch> matches;
  surf.downloadKeypoints(keypoints1GPU, keypoints1);
  surf.downloadKeypoints(keypoints2GPU, keypoints2);
  surf.downloadDescriptors(descriptors1GPU, descriptors1);
  surf.downloadDescriptors(descriptors2GPU, descriptors2);
  BruteForceMatcher_GPU< L2<float> >::matchDownload(trainIdx, distance, matches);
  
  // drawing the results
  Mat img_matches, image1, image2;
  img1.download(image1);
  img2.download(image2);
  drawMatches(image1, keypoints1, image2, keypoints2, matches, img_matches);
