首先请先确认已经安装好了opencv3及以上版本。

#include <opencv2/opencv.hpp>

#include <iostream>

#include <string>

using namespace cv;

using namespace std;

存储

then

int main()

{

//创造一些要存的数据先

string words = "hello, my guys!";

float n = 3.1415926;

Mat m = Mat::eye(3, 3, CV_32F);

//开始创建存储器

FileStorage save("data.yml", FileStorage::WRITE);// 你也可以使用xml格式

save << "words" << words;

save << "number" << n;

save << "matrix" << m;

save.release();

//存储完毕

cout << "finish storing" << endl;

加载

//加载数据，类似Python字典的用法,创建加载器

FileStorage load("data.yml", FileStorage::READ);

float nn;

Mat mm;

string ww;

load["words"] >> ww;

load["number"] >> nn;

load["matrix"] >> mm;

cout<< ww << endl << nn << endl << mm;

cout << endl << "That's the end";

load.release();

return 0;

}
