Ø 菜单项设置如下：

Ø 建立类向导

Ø 编辑代码

void CCVMFCView::OnMyOpenCamera()

{

      // TODO: Add your command handler code here

      //Alt+F8 整理代码

      int   i=1;//截图个数

      CvCapture* capture;

      CString WindowName1="摄像机";

      IplImage *frame = 0;

      capture = cvCreateCameraCapture(0);//打开摄像头

      if(capture==NULL)

      {

             MessageBox("未检测到摄像头，请检查摄像头安装是否正确");

      }

      else

      {

             assert(capture != NULL );//如果没有打开，中断

             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);
