我正在尝试对实时视频源进行霍夫线变换。首先，提要通过一个精巧的边缘检测器运行，该检测器可以完美地工作和输出，然后我通过霍夫线变换运行图像，它会导致“windows 在 openCv.exe 中触发了一个断点”。如果您查看冻结的程序，您可以看到该程序进行了霍夫变换，但随后冻结，弹出一个框，显示“Windows 已触发....”错误
有任何想法吗？
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;
}
