我正在尝试从 BOW 算法中保存词汇。下面是我的代码。

FileStorage fs; 
fs.open("Vocabulary.xml", FileStorage::WRITE); 
Mat vocabulary = bow.cluster(); 
fs << vocabulary ;
fs.release();
FileStorage fs2; 
fs2.open("Vocabulary.xml", FileStorage::READ); 
fs2 ["Vocabulary"] >> vocabulary ;
dextract.setVocabulary(vocabulary);

cv::Mat training_mat(num_img , dictionarySize,CV_32FC1);
cv::Mat labels(num_img,1,CV_32FC1);

CvSVM svm;
svm.load( "trainsvm.xml" );

这是我的错误：

OpenCV Error: Unspecified error (No element name has been given) in unknown function , file c:\opencv\2.4.4\build\include\opencv2\core\operations.hpp , line 2908

您没有在文件中设置词汇表的名称，试试这个：

fs << "Vocabulary" << vocabulary ;
