我正在使用 SURF/FLANN 检测器，我希望将图像、点、描述符保存到一个文件中，以便我可以比较这个图像，它指向第二个图像和点但是当我收到以下错误时试着写：

In file included from detectFlannPoints.cpp:4:0:
/usr/local/include/opencv2/features2d/features2d.hpp:112:17: note: void cv::write(cv::FileStorage&, const string&, const std::vector<cv::KeyPoint>&)
/usr/local/include/opencv2/features2d/features2d.hpp:112:17: note:   candidate expects 3 arguments, 4 provided

这是我用来编写的代码：

  FileStorage fs("Keypoints.yml", FileStorage::WRITE);
  write(fs, "templateImageOne", keypoints_1, tempDescriptors_1);
  fs.release();

我不确定在哪里可以指定额外的参数 ( tempDescriptors_1)，因为删除了这个参数后它可以正常工作。

紧接在编写代码之上的代码：

  //Detect the keypoints using SURF Detector
  int minHessian = 400;
  SurfFeatureDetector detector( minHessian );
  std::vector<KeyPoint> keypoints_1;
  detector.detect( img_1, keypoints_1 );
  //-- Step 2: Calculate descriptors (feature vectors)
  SurfDescriptorExtractor extractor;
  Mat tempDescriptors_1;
  extractor.compute( img_1, keypoints_1, tempDescriptors_1 );
 //-- Draw keypoints
  Mat img_keypoints_1;
  drawKeypoints( img_1, keypoints_1, img_keypoints_1, Scalar::all(-1), DrawMatchesFlags::DEFAULT );

你必须一次写一个：

FileStorage fs("Keypoints.yml", FileStorage::WRITE);
write(fs, "keypoints_1", keypoints_1);
write(fs, "descriptors_1", tempDescriptors_1);
...
fs.release();

我们要一个一个地写出关键点和描述符

FileStorage fs("Keypoints.yml", FileStorage::WRITE);
write(fs, "templateImageOne_Keypoint", keypoints_1);
write(fs, "templateImageOne_descriptor", tempDescriptors_1);
fs.release();
