Visual studio opencv中的链接器问题

Visual studio opencv中的链接器问题,visual-studio,opencv,configuration,Visual Studio,Opencv,Configuration,我正在Visual Studio 2012中使用OpenCV 2.4.6,我测试了一个示例程序,名为matcher_simple.cpp,它匹配两个示例图像image1和image2 #include <stdio.h> #include "opencv2/core/core.hpp" #include "opencv2/features2d/features2d.hpp" #include "opencv2/highgui/highgui.hpp" #include "opencv

#include <stdio.h>

using namespace cv;

    printf("\nThis program demonstrates using features2d detector, descriptor extractor and simple matcher\n"
            "Using the SURF desriptor:\n"
            "\n"
            "Usage:\n matcher_simple <image1> <image2>\n");

int main(int argc, char** argv)

    if(argc != 3)

        help();
        return -1;
    }

    //cv::initModule_nonfree();
    Mat img1 = imread(argv[1], CV_LOAD_IMAGE_GRAYSCALE);
    Mat img2 = imread(argv[2], CV_LOAD_IMAGE_GRAYSCALE);
    if(img1.empty() || img2.empty())
    {
        printf("Can't read one of the images\n");
        return -1;

    // detecting keypoints
    SurfFeatureDetector detector(400);
    vector<KeyPoint> keypoints1, keypoints2;
    detector.detect(img1, keypoints1);
    detector.detect(img2, keypoints2);

    // computing descriptors
    SurfDescriptorExtractor extractor;
    Mat descriptors1, descriptors2;
    extractor.compute(img1, keypoints1, descriptors1);
    extractor.compute(img2, keypoints2, descriptors2);

    // matching descriptors
    BFMatcher matcher(NORM_L2);
    vector<DMatch> matches;
    matcher.match(descriptors1, descriptors2, matches);

    // drawing the results
    namedWindow("matches", 1);
    Mat img_matches;
    drawMatches(img1, keypoints1, img2, keypoints2, matches, img_matches);
    imshow("matches", img_matches);
    waitKey(0);

    return 0;
}

我已经在64位的发布模式下进行了测试,我还成功地运行了简单的其他opencv示例,例如流式实时视频。我在那里没有这些问题。谢谢你的帮助。谢谢。

您必须在非自由模块中链接,因为这是实现冲浪功能的地方

转到项目属性->链接器->输入,将类似opencv_nonfree246d.dll的smth添加到其他依赖项字段
