Windows7 64位机上Emgu CV2 4 2安装与配置

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-gpu2.4.2.1777bin；D:softEmgu2.4.2emgucv-windows-x86-gpu2.4.2.1777binx86(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:softEmgu2.4.2emgucv-windows-x86-gpu2.4.2.1777bin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:softEmgu2.4.2emgucv-windows-x86-gpu2.4.2.1777bin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。
