YAML:如何读写嵌套(递归)的OpenCV文件

#include <opencv2/opencv.hpp>

int main() {
    cv::FileStorage fs("nested_opencv.yaml", cv::FileStorage::READ);
    cv::FileNode rootNode = fs["root"];
    
    // 读取嵌套节点
    cv::FileNode nestedNode = rootNode["nested"];
    
    // 读取嵌套节点中的数据
    int nestedInt = (int)nestedNode["nested_int"];
    float nestedFloat = (float)nestedNode["nested_float"];
    
    // 输出结果
    std::cout << "Nested Int: " << nestedInt << std::endl;
    std::cout << "Nested Float: " << nestedFloat << std::endl;
    
    fs.release();
    
    return 0;
}

#include <opencv2/opencv.hpp>

int main() {
    cv::FileStorage fs("nested_opencv.yaml", cv::FileStorage::WRITE);
    
    // 写入嵌套的节点
    fs << "root" << "{";
    fs << "nested" << "{";
    
    // 写入嵌套节点中的数据
    fs << "nested_int" << 123;
    fs << "nested_float" << 3.14;
    
    fs << "}";
    fs << "}";
    
    fs.release();
    
    return 0;
}
