第一步：下载OpenCV 并安装

我用的版本是2.1 安装后使用灶山CMake 进行了编译配置，具体的方法见OpenCV的官方网站。

第二步：下载QT

这里我下载了三个软件：QTCreator qt-win-opensource-4.7.3-vs2008.exe qt-vs-addin-1.1.9.exe 具体的方法我也不说了，Windows下的QT配置还是很Easy的。

第三步：在带辩袭QTCreator下使用OpenCV

其实也是很简单的，在你的Pro文件下添加一些语句就OK了。我的添加语句如下：

INCLUDEPATH += D:\OpenCV2.1\VS2008\include\opencv

CONFIG(release,debug|release){

LIBS += D:\OpenCV2.1\VS2008\lib\cv210.lib \

D:\OpenCV2.1\VS2008\蠢兄lib\cvaux210.lib \

D:\OpenCV2.1\VS2008\lib\cxcore210.lib \
