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\USB2800\Vcap2820 sdk\Vcap2820 sdk目录下的 devwdm.ax 放到c:\windows\system32\目录下



3、打开 “运行”，输入 Regsvr32 c:\windows\system32\devwdm.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")

[cpp] view
plaincopy

// 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

[cpp] view
plaincopy

#include "devwdm.h"

[cpp] view
plaincopy

void CVideoDemoDlg::OnOK()

{

// TODO: Add extra validation here

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