Question

我试图拼凑一些图像来制作一种全景图。我使用的是OpenCV，所以首先要做的是检测关键点和描述符，而不是匹配它们。为此，请遵循本教程：http://opencv.itseez.com/doc/user_guide/ug_features2d.html 但是在调试期间，我得到一个相对于这一行的std :: bad_alloc异常：

matcher.match(descriptors1, descriptors2, matches);

有人可以帮助我吗？因为我切断了＆amp;粘贴了教程，没有编译错误。

感谢。 ģ

完整代码：

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
BruteForceMatcher<L2<float> > matcher;
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);

如果我运行此代码，我会得到：

运行时检查失败＃2 - 围绕变量＆＃39;关键点1＆＃39;已经腐败了。

代码：

    #include "opencv\cv.h"
    #include "opencv\highgui.h"

    using namespace cv;
    using namespace std;

    int main()
    {
        Mat img1 = imread("Chessboard1.jpg", CV_LOAD_IMAGE_GRAYSCALE);
        Mat img2 = imread("Chessboard3.jpg", CV_LOAD_IMAGE_GRAYSCALE);
        if(img1.empty() || img2.empty())
        {
            printf("Can't read one of the images\n");
            return -1;
        }

        FastFeatureDetector detector(50);
        vector<KeyPoint> keypoints1;
        detector.detect(img1, keypoints1);

        return 0;
    }

您需要确保Properties-＆gt; Linker-＆gt;输入下的“附加依赖项”指的是具有调试器支持的正确OpenCV库。

即

C:\OpenCV2.2\lib\opencv_calib3d220d.lib
C:\OpenCV2.2\lib\opencv_core220d.lib
C:\OpenCV2.2\lib\opencv_features2d220d.lib
C:\OpenCV2.2\lib\opencv_highgui220d.lib
C:\OpenCV2.2\lib\opencv_imgproc220d.lib

而不是

C:\OpenCV2.2\lib\opencv_calib3d220.lib
C:\OpenCV2.2\lib\opencv_core220.lib
C:\OpenCV2.2\lib\opencv_features2d220.lib
C:\OpenCV2.2\lib\opencv_highgui220.lib
C:\OpenCV2.2\lib\opencv_imgproc220.lib
