C++ で opencv を使用してオブジェクトを検出しようとしていますが、エラーが発生します: project1.exe の 0x52f9e470 で未処理の例外: 0xC000001D: 不正な命令。

Windows 7 32 ビット、opencv 2.4.3、visual studio (c++) 2010 を使用し、私のコードは次のとおりです。

   #include <opencv\cv.h>
   #include <opencv\highgui.h>
   #include <stdio.h>
    #include <stdlib.h>
    #include <string.h>
    #include <assert.h>

    #include <limits.h>
   #include <time.h>
   #include <ctype.h>


      // Create a string that contains the exact cascade name
     // Contains the trained classifer for detecting hand
    const char *cascade_name="D:/31dec12/hand.xml";

    //The function detects the hand from input frame and draws a rectangle around the         detected portion of the frame
    void detect_and_draw( IplImage* img )
    {

    // Create memory for calculations
    static CvMemStorage* storage = 0;

    // Create a new Haar classifier
    static CvHaarClassifierCascade* cascade = 0;

   // Sets the scale with which the rectangle is drawn with
   int scale = 1;

   // Create two points to represent the hand locations
   CvPoint pt1, pt2;

    // Looping variable
    int i; 

    // Load the HaarClassifierCascade
    cascade = (CvHaarClassifierCascade*)cvLoad( cascade_name, 0, 0, 0 );

    // Check whether the cascade has loaded successfully. Else report and error and       quit
    if( !cascade )
    {
      fprintf( stderr, "ERROR: Could not load classifier cascade\n" );
     return;
     }

    // Allocate the memory storage
    storage = cvCreateMemStorage(0);

    // Create a new named window with title: result
     cvNamedWindow( "result", 1 );

    // Clear the memory storage which was used before
    cvClearMemStorage( storage );

    // Find whether the cascade is loaded, to find the hands. If yes, then:
    if( cascade )
    {

       // There can be more than one hand in an image. So create a growable sequence of hands.
      // Detect the objects and store them in the sequence
      CvSeq* hands = cvHaarDetectObjects( img, cascade, storage,
                                        1.1, 2, CV_HAAR_DO_CANNY_PRUNING,
                                        cvSize(40, 40) );

      // Loop the number of hands found.
      for( i = 0; i < (hands ? hands->total : 0); i++ )
      {
        // Create a new rectangle for drawing the hand
         CvRect* r = (CvRect*)cvGetSeqElem( hands, i );

          // Find the dimensions of the hand,and scale it if necessary
          pt1.x = r->x*scale;
         pt2.x = (r->x+r->width)*scale;
         pt1.y = r->y*scale;
         pt2.y = (r->y+r->height)*scale;

         // Draw the rectangle in the input image
         cvRectangle( img, pt1, pt2, CV_RGB(230,20,232), 3, 8, 0 );
       }
     }

      cvShowImage( "result", img );


    }


    // A Simple Camera Capture Framework
     int main()
    {

     // Gets the input video stream from camera
     CvCapture* capture = cvCaptureFromCAM( CV_CAP_ANY );

     // Checks if the input stream is obtained
     if( !capture ) 
  {
    fprintf( stderr, "ERROR: capture is NULL \n" );
    getchar();
    return -1;

  // Flips the frame into mirror image 
  cvFlip(frame,frame,1);

   // Call the function to detect and draw the hand positions

どのようなCPUを使用していますか？前回エラーが発生しました: 0xC000001D : 不正な命令は、コードで使用されている SSE 命令に関連していました。いくつかの新しい SSE 命令は AMD プロセッサでは実装されていません。たとえば、SSE サポートなしで opencv を再構築することでこれを修正できます。
