Question

我正在使用opencv 3.3.0

我的代码是

#include <stdio.h>
#include <iostream>
#include "opencv2/core.hpp"
#include "opencv2/imgcodecs.hpp"
#include "opencv2/highgui.hpp"
#include "opencv2/features2d.hpp"
#include "opencv2/xfeatures2d.hpp"
#include <fstream>
#include <string>
#include <vector>

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

int main(int argc, char** argv)
{
    Mat img1;
    img1 = imread("img/img1.jpg", IMREAD_GRAYSCALE);

    if (img1.empty())
    {
        cout << "Could not open or find the image" << endl;
        return -1;
    }

    Ptr<SurfFeatureDetector> detector = SurfFeatureDetector::create(400);
    vector<KeyPoint> keypoints;
    detector->detect(img1, keypoints);

    imshow("img1", img1);
    waitKey(0);
    return 0;
}

我是C++和opencv的新手。该代码在没有冲浪部分的情况下运行良好。

错误

OpenCV错误：cv :: TlsAbstraction :: SetData中的断言失败（TlsSetValue（tlsKey，pData）== TRUE），文件C：\ Users \ Darshana \ Documents \ opencv \ opencv-3.3.0 \ modules \ core \ src \ system.cpp，第1270行

我也试过了Ptr<SURF> detector = SURF::create(400);。

更新

我无法找到解决方案。可能是设置问题或库问题。所以我转到opencv 2.4.13，现在一切正常。我必须更改上面的代码才能使用v2.4.13。

您尚未为SurfFeatureDetector设置参数。我想你应该试试这个：

int minHessian = 400;
SurfFeatureDetector detector(minHessian);
vector<KeyPoint> keypoints;
detector.detect(img1, keypoints);

添加SurfFeatureDetector后，程序给出错误
