将特征点描述子输出成文本

ofstream outFile1,outFile2;//创建对象
outFile1.open("descriptor1.txt");//打开文本
outFile2.open("descriptor2.txt");
//输出左边图像的匹配点描述子
for (int n = 0; n < 128; n++)
{
outFile1 << descriptros1.at<int>(matches[0].queryIdx,n) << endl;
}
//输出右边图像的匹配点描述子
for (int n = 0; n < 128; n++)
{
outFile2 << descriptros2.at<int>(matches[0].trainIdx, n) << endl;
}
outFile1.close();//关闭文本
outFile2.close();
