C++使用OpenCV保存和读取XML
代码
// save xml file
cv::FileStorage file(save_transform, cv::FileStorage::WRITE);
cv::Mat TransM = cv::Mat::ones(100,200,CV_8UC1);
file << "TransM" << TransM;
// read xml file
cv::FileStorage file("xml_file_path", cv::FileStorage::READ);
if (!file.isOpened())
return std::vector<cv::Mat>();
cv::Mat TransM;
file["TransM"] >> TransM;
注意
xml中保存的节点超过4个就会打开失败，opencv的问题。
