Question

我正在尝试使用openCV2计算机视觉应用程序编程菜谱中的代码，在304中为暴力搜索器进行冲浪，但在执行代码时我不断收到此消息：

在surf matrix.exe中0x7530812f处的未处理异常：Microsoft C ++异常：内存位置0x002af6b4处的std :: bad_alloc ..“

我尝试使用谷歌搜索，但找不到答案，我已经检查了这本书的例子，但仍然找不到出错的地方。断点发生在以下声明中：matcher.match(descriptors1,descriptors2, matches);

我正在使用opencv 2.3。我已经包括了

C：\ OpenCV2.3 \构建\包括\ OpenCV的
C：\ OpenCV2.3 \构建\包括\ opencv2
C：\ OpenCV2.3 \ build \ include

在其他包含目录和库下：

opencv_core230.lib
opencv_highgui230.lib
opencv_imgproc230.lib
opencv_features2d230.lib
opencv_calib3d230.lib

...并将C:\OpenCV2.3\build\x86\vc9\lib添加到其他库目录字段

以下是我的代码：

#include "cv.h"
#include "highgui.h"

int main(int argc, char* argv[]) {
    std::vector<cv::KeyPoint> keypoints1, keypoints2;

    cv::Mat image1=cv::imread("C:/Users/folder/44.jpg");
    cv::Mat image2=cv::imread("C:/Users/folder/44.jpg");
    cv::Mat featureImage=cv::imread("C:/Users/folder/44.jpg");
    cvNamedWindow("MyJPG", CV_WINDOW_AUTOSIZE);  
    cv::imshow("MyJPG", image1);
    cv::SurfFeatureDetector surf(2500);
    surf.detect(image1, keypoints1);

    // Draw the keypoints with scale and orientation information
    cv::drawKeypoints(image1, // original image 
        keypoints1, // vector of keypoints 
        featureImage, // the resulting image
        cv::Scalar(255, 255, 255), // color of the points
        cv::DrawMatchesFlags::DRAW_OVER_OUTIMG); //flag 
    cv::imshow("Results", featureImage);

    cv::imshow("MyJPG2", image2);
    surf.detect(image2, keypoints2);
    cv::drawKeypoints(image2, // original image keypoints2, // vector of
        keypoints image2, // the resulting image 
    cv::Scalar(255,255,255), // color of the points
    cv::DrawMatchesFlags::DRAW_OVER_OUTIMG); //flag


    // Construction of the SURF descriptor extractor
    cv::SurfDescriptorExtractor surfDesc1;
    cv::SurfDescriptorExtractor surfDesc2; // Extraction of the SURF descriptors 
    cv::Mat descriptors1, descriptors2;
    surfDesc1.compute(image1, keypoints1, descriptors1);
    //printf("%s",surfDesc);
    surfDesc2.compute(image2, keypoints2, descriptors2);
    cvWaitKey(0);  //  Construction of the matcher 
    cv::BruteForceMatcher<cv::L2<float>> matcher; // Match the two image descriptors 
    std::vector<cv::DMatch> matches;
    matcher.match(descriptors1, descriptors2, matches);

    //cvReleaseImage( &image1 );  
    cvDestroyWindow("MyJPG");
    return 0;
}

在执行opencv2 bruteforce匹配器时分配内存不良
