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文件夾下，運行此.exe文件，將其安裝到D:\soft\Emgu2.4.2\emgucv-windows-x86-gpu2.4.2.1777文件夾下，安裝完后會自動重啟；

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文件夾下包含有對應的OpenCV2.4.2的動態庫，將此目錄加入到環境變量后Emgu不需要額外的安裝相對應的OpenCV)；添加到系統環境變量Path中，重啟；

4.????? 打開vs2008，新建一個基于Windows窗體的應用程序；

5.????? 導入UI插件：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打開，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。
