c++ - 实时视频上的 Hough 线变换会导致断点？

Question

我正在尝试对实时视频源运行霍夫线变换。首先，提要通过一个精明的边缘检测器，它可以完美地工作并输出，然后我通过霍夫线变换运行图像，它导致“windows 触发了 openCv.exe 中的断点。”如果您查看卡住的程序，您可以看到该程序进行了霍夫变换但随后卡住，弹出一个框并显示“Windows 已触发...”错误

有什么想法吗？

代码:

#include "opencv2/highgui/highgui.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include <iostream>
#include <stdio.h>
#include <stdlib.h>

using namespace std;
using namespace cv;

int main(int, char**)
{
    namedWindow( "Edges", CV_WINDOW_NORMAL ); 
    CvCapture* capture = cvCaptureFromCAM(-1);

    Mat frame; 
    Mat out; 
    Mat out2;
    Mat canny;
    Mat hough;
    while(1) {
        frame = cvQueryFrame( capture );
        imshow("Source",frame);
        GaussianBlur( frame, out, Size(5, 5), 0, 0 );
        cvtColor( out ,out2, CV_BGR2GRAY ); // produces out2, a one-channel image (CV_8UC1)
     Canny( out2, canny, 100, 200, 3 ); // the result goes to out2 again,but since it is still one channel it is fine
     imshow( "Canny", canny );


 cvtColor(canny, hough, CV_GRAY2BGR);
  vector<Vec4i> lines;
  HoughLinesP(canny, lines, 1, CV_PI/180, 50, 100, 10 );
  for( size_t i = 0; i < lines.size(); i++ )
  {
   Vec4i l = lines[i];
   //line( hough, Point(l[0], l[1]), Point(l[2], l[3]), Scalar(0,0,255), 3, CV_AA);
   cout << Point(l[0], l[1]) << endl;
   cout << Point(l[2], l[3]) << endl;
  }

  imshow("Lines", hough);

      if( !frame.data ) break;


        char c = cvWaitKey(33);
        if( c == 'c' ) break;
    }
    return 0;
}

Answer 1

根据我的经验，我猜问题是你的程序将opencv链接为DLL，它与CRT的链接与你的EXE中的不同。

因此，您传递给 HoughLinesP 的 vector 在 DLL 模块内部分配内存，然后您在外部释放。由于CRT的联动方式不同，其内存池也不一样，所以就麻烦了。

解决方法也很简单，就是进入项目属性页 -> C/C++ -> Code Generation，然后更改Runtime Library 与您的 opencv 项目具有相同的值(value)。
