c++ - 对象识别 OpenCV 中未处理的异常

Question

我正在执行 OpenCV 示例文件夹中关于对象检测的代码。以下是以下代码：

<pre><code>#include "opencv2/objdetect/objdetect.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/imgproc/imgproc.hpp"

#include "iostream"
#include "stdio.h"

using namespace std;
using namespace cv;


void detectAndDisplay( Mat frame );

String face_cascade_name = "E:/opencv/data/haarcascades/haarcascade_frontalface_alt.xml";
String eyes_cascade_name = "E:/opencv/data/haarcascades/haarcascade_eye_tree_eyeglasses.xml";
CascadeClassifier face_cascade;
CascadeClassifier eyes_cascade;
string window_name = "Capture - Face detection";
RNG rng(12345);

int main( int argc, const char** argv )
{
  CvCapture* capture;
  Mat frame;


  if( !face_cascade.load( face_cascade_name ) ){ printf("--(!)Error loading1\n"); return -1; };
  if( !eyes_cascade.load( eyes_cascade_name ) ){ printf("--(!)Error loading2\n"); return -1; };


  capture = cvCaptureFromCAM( -1 );
  if( capture )
  {
    while( true )
    {
      frame = cvQueryFrame( capture );


      if( !frame.empty() )
       { detectAndDisplay( frame ); }
      else
       { printf(" --(!) No captured frame -- Break!"); break; }

      int c = waitKey(10);
      if( (char)c == 'c' ) { break; }

    }
  }
  return 0;
}

void detectAndDisplay( Mat frame )
{
   std::vector<Rect> faces;
   Mat frame_gray;

   cvtColor( frame, frame_gray, CV_BGR2GRAY );
   equalizeHist( frame_gray, frame_gray );

   face_cascade.detectMultiScale( frame_gray, faces, 1.1, 2, 0|CV_HAAR_SCALE_IMAGE, Size(30, 30) );

   for( int i = 0; i < faces.size(); i++ )
    {
      Point center( faces[i].x + faces[i].width*0.5, faces[i].y + faces[i].height*0.5 );
      ellipse( frame, center, Size( faces[i].width*0.5, faces[i].height*0.5), 0, 0, 360, Scalar( 255, 0, 255 ), 2, 8, 0 );

      Mat faceROI = frame_gray( faces[i] );
      std::vector<Rect> eyes;


      eyes_cascade.detectMultiScale( faceROI, eyes, 1.1, 2, 0 |CV_HAAR_SCALE_IMAGE, Size(30, 30) );

      for( int j = 0; j < eyes.size(); j++ )
       {
         Point center( faces[i].x + eyes[j].x + eyes[j].width*0.5, faces[i].y + eyes[j].y + eyes[j].height*0.5 );
         int radius = cvRound( (eyes[j].width + eyes[j].height)*0.25 );
         circle( frame, center, radius, Scalar( 255, 0, 0 ), 3, 8, 0 );
       }
    }

   imshow( window_name, frame );
}
</code></pre>

在调试代码时，它会引发以下异常

<pre><code>Unhandled exception at 0x5788bf1d in corner.exe: 0xC000001D: Illegal Instruction.</pre></code>

谁能帮我解决问题？

试试 haarcascade_frontalface_alt2.xml 。
