如何在vc中调用摄像头并把捕获的图像保存为bmp图片？

[dong048]

我想做一个用摄像头拍照的程序，如何在vc中调用摄像头并把捕获的图像保存为bmp图片？哪位大虾可以贴个代码上来吗？

[EddieCai]

摄像头驱动支持TWAIN接口么？

这个有意思，关注下

用VFW啊，很简单的~~你Google一下C++,Video Capture着关键词

[dong048]

没有人能帮帮我吗?

void CRobotDlg::OnBufsave()
{
// TODO: Add your control notification handler code here
char* FileName;
FileName="E:\\tuxiang.bmp";
bufSave(m_hbuf,FileName);

}
你试着模仿这段代码！
图像存取应该是比较简单的~

hwndc = capCreateCaptureWindow ( "my own capture window",
WS_CHILD | WS_VISIBLE , 11 , 11,rectCapsWindow.Width(), rectCapsWindow.Height() ,this->m_hWnd,10001);
//::MoveWindow(hwndc,rectCapsWindow.left,rectCapsWindow.top,rectCapsWindow.Width(),rectCapsWindow.Height(),TRUE);

CAPDRIVERCAPS CapDrvCaps;

::SendMessage ( hwndc, WM_CAP_DRIVER_CONNECT, 0 /* windex */, 0l);

::SendMessage( hwndc, WM_CAP_DRIVER_GET_CAPS,
sizeof(CAPDRIVERCAPS), (LONG) (LPVOID) &CapDrvCaps);

// set preview rate to 66 miliseconds
capPreviewRate( hwndc, 1 );
// start preview video
capPreview( hwndc, TRUE ); //开始预览
capDlgVideoFormat(hwndc); //改变摄像头分辨率，及大小


capFileSaveDIB(hwndc,"C:\\1.bmp");

太长了不让发!去google搜"利用VFW进行视频捕捉"吧!有代码!

[taianmonkey]

找找有个叫陆其明的人的网站，他写过这方面的东西！

用DirectShow吧
