Question

我有Opencv3.1并与opencv_contrib一起安装。我可以成功构建以下代码。

#include <opencv2/opencv.hpp>
#include "opencv2/core.hpp"
#include "opencv2/features2d.hpp"
#include "opencv2/xfeatures2d.hpp"
#include "opencv2/highgui.hpp"
#define USE_SURF
#define USE_FLANN

using namespace std;
using namespace cv;
using namespace cv::xfeatures2d;

int imagematching(Mat &first, Mat & second)
{


   return 0;
}

这意味着，我的xfeatures2d已成功安装。然后，当我包括

int imagematching(Mat &first, Mat & second)
{
    int max_keypoints = 500;
    Ptr<SURF> detector = SURF::create( max_keypoints );

    return 0;
}

然后我有错误

Opencv3.1中的SURF有什么问题？感谢

如何在Opencv3.1中使用SURF？
