Windows7 64位機上Emgu CV2.4.2安裝與配置

1.      從http://sourceforge.net/projects/emgucv/?source=directory下載最新的Emgu
CV2.4.2；

2.      將libemgucv-windows-x86-gpu-2.4.2.1777拷貝到D:\soft\Emgu2.4.2檔案夾下，運行此.exe檔案，將其安裝到D:\soft\Emgu2.4.2\emgucv-windows-x86-gpu2.4.2.1777檔案夾下，安裝完後會自動重啟；

3.      將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檔案夾下包含有對應的OpenCV2.4.2的動態庫，將此目錄加入到環境變數後Emgu不需要額外的安裝相對應的OpenCV)；添加到系統內容變數Path中，重啟；

4.      開啟vs2008，建立一個基於Windows表單的應用程式；

5.      匯入UI外掛程式：Tool-->Choose Toolbox Items-->.NET
Framework Components-->點擊Browse，選中D:\soft\Emgu2.4.2\emgucv-windows-x86-gpu2.4.2.1777\bin下的Emgu.CV.UI.dll開啟，會在列表中新增HistogramBox、ImageBox、MatrixBox、PanAndZoomPictureBox四項；

6.      添加引用：選中工程下的References-->Add Reference-->Browse選中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個動態庫，點擊OK；

7.      點擊Solution Platforms-->Configuration Manager：Active solution
platform將原來的Any CPU改為x86，否則會提示“Emgu.CV.CvInvoke的類型初始值設定項引發異常”的錯誤。

網上的一個程式碼範例，編譯、運行成功：

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;//判斷網路攝影機的狀態

       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//網路攝影機為空白，則通過Capture()方法調用

           {

               try

               {

                   capture=
newCapture();

               }

               catch(NullReferenceExceptionexcpt)

               {

                   MessageBox.Show(excpt.Message);

               }

           }

       }

       privatevoidprocessframe(objectsender,
EventArgsarg)

       {

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

           imageBox1.Image =frame;

       }

   
}

}
