VS2008编写MFC程序--使用opencv2.4（）

开始记录VS2008环境下学习OPENCV2.4

头文件：

#pragma once
#include "CvvImage.h"
#include "opencv/cv.h"
#include "opencv/highgui.h"

定义全局变量：

在*dlg.cpp

CvCapture* capture;
CRect rect;
CDC *pDC;
HDC hDC;
CWnd *pwnd;

CPP文件：

void Cvedio_mfcDlg::OnBnClickedButton1()
{
    // TODO: Add your control notification handler code here
    if(!capture)
    {
        capture = cvCaptureFromCAM(0);
        //AfxMessageBox("OK");
    }

    if (!capture)
    {
        AfxMessageBox("无法打开摄像头");
        return;
    }

    // 测试
    IplImage* m_Frame;
    m_Frame=cvQueryFrame(capture);
    CvvImage m_CvvImage;
    m_CvvImage.CopyOf(m_Frame,1);    
    if (true)
    {
        m_CvvImage.DrawToHDC(hDC, &rect);
        //cvWaitKey(10);
    }

    // 设置计时器,每10ms触发一次事件
    SetTimer(1,10,NULL);
}

void Cvedio_mfcDlg::OnTimer(UINT_PTR nIDEvent)
{
    // TODO: Add your message handler code here and/or call default
    /************************************************************************/
    /* 显示摄像头                                                           */
    /************************************************************************/
    IplImage* m_Frame;
    m_Frame=cvQueryFrame(capture);
    CvvImage m_CvvImage;
    m_CvvImage.CopyOf(m_Frame,1);    
    if (true)
    {
        m_CvvImage.DrawToHDC(hDC, &rect);
        //cvWaitKey(10);
    }


    CDialog::OnTimer(nIDEvent);
}

void Cvedio_mfcDlg::OnBnClickedButton2()
{
    // TODO: Add your control notification handler code here
    cvReleaseCapture(&capture);
    CDC MemDC; 
    CBitmap m_Bitmap1;
    m_Bitmap1.LoadBitmap(IDB_BITMAP1); 
    MemDC.CreateCompatibleDC(NULL);
    MemDC.SelectObject(&m_Bitmap1);
    pDC->StretchBlt(rect.left,rect.top,rect.Width(),rect.Height(),&MemDC,0,0,48,48,SRCCOPY); 
}
