版本1.0.3新增內容

打開攝像頭

Ø 新建菜單項，Learning OpenCV——> OpenCVr入門——>打開攝像頭(c)

Ø 菜單項設置如下：

Ø 建立類向導

Ø 編輯代碼

void CCVMFCView::OnMyOpenCamera()

{

      // TODO: Add your command handler code here

      //Alt+F8 整理代碼

      int   i=1;//截圖個數

      CvCapture* capture;

      CString WindowName1="攝像機";

      IplImage *frame = 0;

      capture = cvCreateCameraCapture(0);//打開攝像頭

      if(capture==NULL)

      {

             MessageBox("未檢測到攝像頭，請檢查攝像頭安裝是否正確");

      }

      else

      {

             assert(capture != NULL );//如果沒有打開，中斷

             cvNamedWindow(WindowName1,CV_WINDOW_AUTOSIZE);

             while(1)

             {

                    frame= cvQueryFrame(capture);

                    if(!frame)

                    {

                           break;

                    }

                    cvShowImage(WindowName1, frame );

                    char c = cvWaitKey(10);

                    if( c == 27 )

                    {

                           break;

                    }

                    else if(c=='c'||c=='C')

                    {

                           CString str;

                           str.Format( "%d ",i);

                           CString WindowName2="Capture"+str;

                           cvNamedWindow(WindowName2,CV_WINDOW_AUTOSIZE);

                           cvShowImage(WindowName2, frame);

                           cvWaitKey(0);

                           cvDestroyWindow(WindowName2);

                           i++;

                    }

                   

             }

             cvReleaseCapture( &capture );

             cvDestroyWindow(WindowName1);

      }

}
