用了ORB那么久，今天第一次将256bit的描述子打印出来，直观看到了match的汉明距离。

上代码：

#include <iostream>
#include <bitset>
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/features2d/features2d.hpp>

using namespace std;
using namespace cv;

int main()
{
	Mat image = imread("t.png");
	Mat image1 = imread("t1.png");
	Mat gray,gray1;
	cvtColor(image, gray, CV_BGR2GRAY);
	cvtColor(image1, gray1, CV_BGR2GRAY);
	ORB orb(1000);
	vector<KeyPoint> keypoints,keypoints1;
	orb.detect(gray, keypoints);
	orb.detect(gray1, keypoints1);
	Mat descriptors, descriptors1;
	orb.compute(gray, keypoints, descriptors);
	orb.compute(gray1, keypoints1, descriptors1);
