我試圖在實時視頻Feed上運行hough line變換。首先，feed會通過canny邊緣檢測器完成工作和輸出，然後通過hough line transform運行圖像，並導致「windows在openCv.exe中觸發斷點」。如果你看看凍結的程序，你可以看到程序做了hough變換，但隨後凍結，一個盒子彈出「Windows已觸發....」錯誤Hough Line在實況視頻中轉換會導致斷點？
任何想法？
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;
}
