VC++中视频采集系统（摄像头的制作，串口通信的应用）

1、插入摄像头，安装驱动  VCap2800  USB2.0 DRV（windows 7）或者Vcap2820 sdk，两者依次尝试

 

注意：驱动有一下几种，如果USB2.0 DRVB不成功！！可以换驱动VCap2820 sdk进行尝试!!!

 

 

2、G:VC++视频采集资料USB2800Vcap2820 sdkVcap2820 sdk目录下的    devwdm.ax   放到c:windowssystem32目录下

3、打开 “运行”，输入   Regsvr32  c:windowssystem32devwdm.ax   进行注册驱动 

4、创建VC工程，基于对话框

5、添加devwdm.dll  devwdm.h  devwdm.lib到项目中，这些是摄像头的相关API

5、在StdAfx.h文件中加载动态链接库
      #pragma comment(lib,"devwdm.lib")

// stdafx.h : include file for standard system include files,
//  or project specific include files that are used frequently, but
//      are changed infrequently
//

#if !defined(AFX_STDAFX_H__1357FC0D_0191_4DD3_8CB5_4A15DA0B970C__INCLUDED_)
#define AFX_STDAFX_H__1357FC0D_0191_4DD3_8CB5_4A15DA0B970C__INCLUDED_

#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000

#define VC_EXTRALEAN        // Exclude rarely-used stuff from Windows headers

#include <afxwin.h>         // MFC core and standard components
#include <afxext.h>         // MFC extensions
#include <afxdisp.h>        // MFC Automation classes
#include <afxdtctl.h>     // MFC support for Internet Explorer 4 Common Controls
#ifndef _AFX_NO_AFXCMN_SUPPORT
#include <afxcmn.h>           // MFC support for Windows Common Controls
#endif // _AFX_NO_AFXCMN_SUPPORT

//注册动态链接库
#pragma comment(lib,"devwdm.lib")

//{{AFX_INSERT_LOCATION}}
// Microsoft Visual C++ will insert additional declarations immediately before the previous line.

#endif // !defined(AFX_STDAFX_H__1357FC0D_0191_4DD3_8CB5_4A15DA0B970C__INCLUDED_)

6、添加头文件到响应的cpp应用文件中，进行测试

#include "devwdm.h"

 

void CVideoDemoDlg::OnOK()
{
    // TODO: Add extra validation here

    devwdm_InitCard(0,m_static.m_hWnd,300,400);//
