配置OpenCv:
一、新建工程
无论是mfc还是控制台程序都可以。
二、下载opencb，安装在非空格路径下面
解压出来有两个文件夹：build和source，主要用到build，build-x86里有三个文件夹，针对不同的vs版本：vc10 = Visual Studio 2010，vc11 = Visual Studio 2012，vc12 = Visual Studio 2013。
三、配置环境
1、 包含目录
右键项目-属性-C++目录-包含目录，添加
opencvuildinclude
opencvuildincludeopencv
opencvuildincludeopencv2 这三个目录（记得是绝对路径,这里没有写全）
2、 库目录
右键项目-属性- C++目录-库目录，添加
opencvuildx86vc10lib（记得是绝对路径,这里没有写全，x86表示32位电脑，x64表示64位电脑）
3、 链接库
右键项目-属性-链接器-输入-附加依赖项，添加opencvuildx86vc12lib里的lib文件，如
opencv_calib3d2410.lib代表release版本，
opencv_calib3d2410d.lib代表debug版本；
在附加依赖项里：按顺序先添加所有debug的lib，再添加release的版本：
opencv_ml2410d.lib
opencv_calib3d2410d.lib
opencv_contrib2410d.lib
opencv_core2410d.lib
