我正在尝试对实时视频Feed进行hough line变换。首先，Feed通过一个精确工作和输出的canny边缘检测器运行，然后我通过hough line变换运行图像，它会导致“windows在openCv.exe中触发断点”。如果你查看冻结的程序，你可以看到该程序进行了霍夫转换，但随后它冻结了，弹出一个框“Windows触发了......”错误
有什么想法吗？
CODE：
#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;

HEAP[openCV.exe]: Invalid address specified to RtlFreeHeap( 028A0000, 037EBA68 )
Windows has triggered a breakpoint in openCV.exe.
This may be due to a corruption of the heap, which indicates a bug in openCV.exe or any of the DLLs it has loaded.
This may also be due to the user pressing F12 while openCV.exe has focus.

答案 0 :(得分：0)
根据我的经验，我猜问题是您的程序将opencv链接为DLL，并且它与CRT的链接与EXE中的链接不同。
因此传递给HoughLinesP的向量会在DLL模块内部分配内存，然后在外部释放。由于CRT的链接不同，它的内存池也不一样，所以你遇到了麻烦。
解决方案很简单，只需投影属性页 - ＆gt; C / C ++ - ＆gt; 代码生成，然后将运行时库更改为与opencv项目相同的值。
