C ++上的分段错误

Question

我是编程新手。我想使用openCV制作一个程序来拍摄图像并对其进行处理。我已经调试了所有错误和警告，但是清除错误和警告后，仍然存在问题细分问题

我们已经尝试了很多方法，但是仍然可以解决此问题。我们使用C ++编程语言。

这是我的代码：

using namespace cv;
using namespace std;
Mat src;
Mat src_gray;
int thresh = 100;
int max_thresh = 255;
RNG rng(12345);

/// Function header

/**
 * @function main
 */
int main(int, char** argv) {
  while (true) {
    void thresh_callback(int, void*);
    time_t timer_begin, timer_end;
    raspicam::RaspiCam_Cv Camera;
    cv::Mat image;
    int nCount = 5;
    // set camera params
    Camera.set(CV_CPU_POPCNT, CV_8UC1);
    // Open camera
    // cout<<"Opening Camera..."<<endl;
    if (!Camera.open()) {
      cerr << "Error opening the camera" << endl;
      return -1;
    }
    // Start capture
    // cout<<"Capturing "<<nCount<<" frames ...."<<endl;
    time(&timer_begin);
    for (int i = 0; i < nCount; i++) {
      Camera.grab();
      Camera.retrieve(image);
      if (i % 5 == 0)
        ;  // cout<<"\r captured "<<i<<" images"<<std::flush;
    }
    // cout<<"Stop camera..."<<endl;
    Camera.release();
    // show time statistics
    time(&timer_end); /* get current time; same as: timer = time(NULL)  */
    double secondsElapsed = difftime(timer_end, timer_begin);
    // cout<< secondsElapsed<<" seconds for "<< nCount<<"  frames : FPS = "<<  (
    // float ) ( ( float ) ( nCount ) /secondsElapsed ) <<endl;
    // save image
    cv::imwrite("gbrkayu.jpg", image);
    // cout<<"gbrkayu.jpg"<<endl;

    // Load source image and convert it to gray
    // char* "home/pi/BoundingBox/kayu.jpg"
    src = imread("gbrkayu.jpg", 1);
    resize(src, src, Size(160, 120));

    // Convert image to gray and blur it
    cvtColor(src, src_gray, COLOR_BGR2GRAY);
    blur(src_gray, src_gray, Size(3, 3));

    // Create Window
    const char* source_window = "Source";
    namedWindow(source_window, WINDOW_AUTOSIZE);
    imshow(source_window, src);

    createTrackbar(" Threshold:", "Source", &thresh, max_thresh,
                   thresh_callback);
    thresh_callback(0, 0);

    waitKey(10);
    //  return(0);
  }
}

请帮助，我将非常感谢。
