我曾尝试的代码如下。结果并不令人满意。我该如何改进?
#include <iostream>
#include "opencv2/core/core.hpp"
#include "opencv2/features2d/features2d.hpp"
#include "opencv2/highgui/highgui.hpp"
#include <iostream>
#include <vector>
using namespace cv;
using namespace std;
int main()
{
Mat img_1 = imread("D:\\image\\img1.jpg");
Mat img_2 = imread("D:\\image\\img2.jpg");
if (!img_1.data || !img_2.data)
{
cout << "error reading images " << endl;
return -1;
}
ORB orb;
vector<KeyPoint> keyPoints_1, keyPoints_2;
Mat descriptors_1, descriptors_2;
orb(img_1, Mat(), keyPoints_1, descriptors_1);
orb(img_2, Mat(), keyPoints_2, descriptors_2);
BruteForceMatcher<HammingLUT> matcher;
vector<DMatch> matches;
matcher.match(descriptors_1, descriptors_2, matches);
double max_dist = 0; double min_dist = 100;
//-- Quick calculation of max and min distances between keypoints
for(int i = 0; i < descriptors_1.rows; i++)
{
double dist = matches[i].distance;
if(dist < min_dist) min_dist = dist;
if(dist > max_dist) max_dist = dist;
}
printf("-- Max dist : %f \n", max_dist);
printf("-- Min dist : %f \n", min_dist);
//-- Draw only "good" matches (i.e. whose distance is less than 0.6*max_dist)
//-- PS.- radiusMatch can also be used here.
std::vector<DMatch> good_matches;
for(int i = 0; i < descriptors_1.rows; i++)
{
if(matches[i].distance < 0.6*max_dist)
{
good_matches.push_back(matches[i]);
}
}
Mat img_matches;
drawMatches(img_1, keyPoints_1, img_2, keyPoints_2,
good_matches, img_matches, Scalar::all(-1), Scalar::all(-1),
vector<char>(), DrawMatchesFlags::NOT_DRAW_SINGLE_POINTS);
imshow("Match", img_matches);
cvWaitKey();
return 0;
}
您可以使用您提到的任何特征描述符。无论哪个给你最好的结果。那就是说,那么问题是什么? – 2014-10-06 16:59:19
我使用ORB描述符进行检测。但是,结果似乎并不好。 – user3217504 2014-10-07 08:17:56
在某些领域,每个这些描述符都很坚强。即使你知道背后的理论,挑选一个可能有点棘手。 – 2014-10-07 08:29:56
