    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:softEmgu2.4.2文件夹下,运行此.exe文件,将其安装到D:softEmgu2.4.2emgucv-windows-x86-gpu2.4.2.1777文件夹下,安装完后会自动重启;

    3.      将D:softEmgu2.4.2emgucv-windows-x86-gpu2.4.2.1777inD:softEmgu2.4.2emgucv-windows-x86-gpu2.4.2.1777inx86(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:softEmgu2.4.2emgucv-windows-x86-gpu2.4.2.1777in下的Emgu.CV.UI.dll打开,会在列表中新增HistogramBoxImageBoxMatrixBoxPanAndZoomPictureBox四项;

    6.      添加引用:选中工程下的References-->Add Reference-->Browse选中D:softEmgu2.4.2emgucv-windows-x86-gpu2.4.2.1777in下的Emgu.CV.dllEmgu.CV.ML.dll  Emgu.CV.UI.dll Emgu.Util.dllZedGraph.dll 5个动态库,点击OK

    7.      点击Solution Platforms-->Configuration ManagerActive 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;

    usingSystem.Collections.Generic;

    usingSystem.ComponentModel;

    usingSystem.Data;

    usingSystem.Drawing;

    usingSystem.Linq;

    usingSystem.Text;

    usingSystem.Windows.Forms;

     

    usingEmgu.CV;//Emgu

    usingEmgu.CV.Structure;

    usingEmgu.Util;

    usingSystem.Threading;

     

    namespaceTestEmgu

    {

        public partial class Form1 : Form

        {

           public Form1()

           {

               InitializeComponent();

           }

     

           privateCapturecapture;

           privateboolcaptureinprocess;//判断摄像头的状态

     

           privatevoidbutton1_Click(objectsender, EventArgse)

           {

               if(capture !=null)

               {

                   if(captureinprocess)

                   {

                       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

                   {

                       capture= newCapture();

                   }

                   catch(NullReferenceExceptionexcpt)

                   {

                       MessageBox.Show(excpt.Message);

                   }

               }

           }

     

           privatevoidprocessframe(objectsender, EventArgsarg)

           {

               Image<Bgr,Byte>frame =capture.QueryFrame();

     

               imageBox1.Image =frame;

           }

        }

    }
