1. 从http://sourceforge.net/projects/emgucv/?source=directory下载最新的Emgu CV2.4.2;
2. 将libemgucv-windows-x86-gpu-2.4.2.1777拷贝到D:\soft\Emgu2.4.2文件夹下,运行此.exe文件,将其安装到D:\soft\Emgu2.4.2\emgucv-windows-x86-gpu2.4.2.1777文件夹下,安装完后会自动重启;
3. 将D:\soft\Emgu2.4.2\emgucv-windows-x86-gpu2.4.2.1777\bin;D:\soft\Emgu2.4.2\emgucv-windows-x86-gpu2.4.2.1777\bin\x86(此x86文件夹下包含有对应的OpenCV2.4.2的动态库,将此目录加入到环境变量后Emgu不需要额外的安装相对应的OpenCV);添加到系统环境变量Path中,重启;
4. 打开vs2008,新建一个基于Windows窗体的应用程序;
5. 导入UI插件:Tool-->Choose Toolbox Items-->.NET Framework Components-->点击Browse,选中D:\soft\Emgu2.4.2\emgucv-windows-x86-gpu2.4.2.1777\bin下的Emgu.CV.UI.dll打开,会在列表中新增HistogramBox、ImageBox、MatrixBox、PanAndZoomPictureBox四项;
6. 添加引用:选中工程下的References-->Add Reference-->Browse选中D:\soft\Emgu2.4.2\emgucv-windows-x86-gpu2.4.2.1777\bin下的Emgu.CV.dll、Emgu.CV.ML.dll、 Emgu.CV.UI.dll、 Emgu.Util.dll、ZedGraph.dll 5个动态库,点击OK;
7. 点击Solution Platforms-->Configuration Manager:Active solution platform将原来的Any CPU改为x86,否则会提示“Emgu.CV.CvInvoke的类型初始值设定项引发异常”的错误。
网上的一个代码示例,编译、运行成功:

usingSystem.Windows.Forms;
usingEmgu.CV;//Emgu

usingSystem.Threading;
namespaceTestEmgu

{

}
privateCapturecapture;
privateboolcaptureinprocess;//判断摄像头的状态
privatevoidbutton1_Click(objectsender, EventArgse)
{
if(capture !=null)
{

{
Application.Idle -=new EventHandler(processframe);
button1.Text ="stop!";
}
else
{
Application.Idle +=new EventHandler(processframe);
button1.Text ="start!";
}
captureinprocess= !captureinprocess;
}
else//摄像头为空,则通过Capture()方法调用
{
try

}
catch(NullReferenceExceptionexcpt)
{
MessageBox.Show(excpt.Message);
}
}
}
privatevoidprocessframe(objectsender, EventArgsarg)
{
Image<Bgr,Byte> frame =capture.QueryFrame();
imageBox1.Image =frame;
}
}
}
