VS2010平台下OpenCV 248编译和安装

这次安装OpenCV算是对windows下的系统路径设置有了更深的了解，还用CMake编译了OpenCV源码。OpenCV官方的系统路径设置方法：

Set the OpenCV enviroment variable and add it to the systems path
First we set an enviroment variable to make easier our work. This will hold the build directory of our OpenCV library
that we use in our projects. Start up a command window and enter:
setx -m OPENCV_DIR D:\OpenCV\Build\x86\vc10 (suggested for Visual Studio 2010 - 32 bit Windows)
setx -m OPENCV_DIR D:\OpenCV\Build\x64\vc10 (suggested for Visual Studio 2010 - 64 bit Windows)
setx -m OPENCV_DIR D:\OpenCV\Build\x86\vc11 (suggested for Visual Studio 2012 - 32 bit Windows)
setx -m OPENCV_DIR D:\OpenCV\Build\x64\vc11 (suggested for Visual Studio 2012 - 64 bit Windows)
Here the directory is where you have your OpenCV binaries (extracted or built). You can have different platform (e.g.
x64 instead of x86) or compiler type, so substitute appropriate value. Inside this you should have two folders called
lib and bin. The -m should be added if you wish to make the settings computer wise, instead of user wise.

If you built static libraries then you are done. Otherwise, you need to add the bin folders path to the systems path. This
is cause you will use the OpenCV library in form of “Dynamic-link libraries” (also known as DLL). Inside these are
stored all the algorithms and information the OpenCV library contains. The operating system will load them only on
demand, during runtime. However, to do this he needs to know where they are. The systems PATH contains a list of
folders where DLLs can be found. Add the OpenCV library path to this and the OS will know where to look if he ever
needs the OpenCV binaries. Otherwise, you will need to copy the used DLLs right beside the applications executable
file (exe) for the OS to find it, which is highly unpleasent if you work on many projects. To do this start up again the
Path Editor and add the following new entry (right click in the application to bring up the menu):
%OPENCV_DIR%\bin

Save it to the registry and you are done. If you ever change the location of your build directories or want to try out your
applicaton with a different build all you will need to do is to update the OPENCV_DIR variable via the setx command
inside a command window.

这样比打开windows管理-》高级系统设置-》环境变量 再设置方便不到哪去，但是这样直接写到注册表，不用再重启电脑了是不是很爽啊。里面还推荐了一个软件，Path Editor，http://patheditor2.codeplex.com/

要点：

           1) XP+ Visual Stuio 2010 + OpenCV-2.4.2.exe + cmake-2.8.8-win32-x86.exe 

           2) 如何CMake OpenCV源代码得到可编译的VS2010项目

           3) 如何使用VS2010编译OpenCV源码

           4) 如何配置OpenCV工程

1. 下载OpenCV 安装包

     OpenCV-2.4.2.exe  （http://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.4.2/）

2. 解压安装包

    双击OpenCV-2.4.2.exe 解压，比如解压安装到C:\openCV_extract

    【这里面是OpenCV自带的dll库，无法用来在VS中调试OpenCV，所以需要使用CMake重新编译】

3.  安装CMake

     cmake-2.8.8-win32-x86.exe （http://www.cmake.org/cmake/resources/software.html）

4. CMake OpenCV

    源代码选择OpenCV安装目录C:/openCV_extract/opencv

    Build目录可以设置为C:/openCV-extract/opencv_build

    点击Configure

    完成后，出现红色背景，

    勾选BUILD_SHARED_LIBS，BUILD_TESTS，OPENCV_BUILD_3DPARTY_LIBS，以及下面的WITH_JASPER，WITH_JPEG，WITH_PNG，WITH_TBB（一般这个没默认选上），和WITH_TIFF选项

    点击Generate

    

5.  编译CMake出来的工程

    （1）打开C:/openCV-extract/opencv_build目录下的VS2010工程文件OpenV.sln

    （2）分别使用Debug和Release模式，编译生成。

    （3）复制opencv_build目录下的bin和lib文件夹，到C:\openCV_extract\opencv目录下

              复制opencv\build\include 目录下的两个文件夹，到opencv\include 下，覆盖。

             

    这样得到的库文件，就可以被VS2010调用了。

      

6.  配置系统环境变量

    在PATH变量中添加：

    C:\openCV_extract\opencv\build\x86\vc10\bin;C:\ openCV_extract \opencv\bin\Debug\;C:\ openCV_extract \opencv\bin\Release\

7.  新建Win32工程，配置工程属性

     （1）VC++ Directories 下的Include Directories 

        （bin\debug可以不用加）

        

      （2）VC++ Directories 下的Library Directories 

             Debug模式为：lib\Debug

             Release模式为：lib\Release

         

     

      （3）添加库文件  Linker --> Input --> Additional Dependencies  （注意：lib文件名根据不同的opencv版本而定）

        Debug模式添加：

             opencv_calib3d242d.lib

opencv_contrib242d.lib

opencv_core242d.lib

opencv_features2d242d.lib

opencv_flann242d.lib

opencv_gpu242d.lib

opencv_haartraining_engined.lib

opencv_highgui242d.lib

opencv_imgproc242d.lib

opencv_legacy242d.lib

opencv_ml242d.lib

opencv_objdetect242d.lib

opencv_ts242d.lib

opencv_video242d.lib

       Release模式添加：    

          opencv_calib3d242.lib

opencv_contrib242.lib

opencv_core242.lib

opencv_features2d242.lib

opencv_flann242.lib

opencv_gpu242.lib

opencv_haartraining_engine.lib

opencv_highgui242.lib

opencv_imgproc242.lib

opencv_legacy242.lib

opencv_ml242.lib

opencv_objdetect242.lib

opencv_ts242.lib

opencv_video242.lib

8. 编码运行

    

[cpp] view plaincopy

1. #include "stdafx.h"  
2. #include "highgui.h"  
3. //using namespace cv;  
4.  int _tmain(int argc, _TCHAR* argv[])  
5. {    const char* imagename = "D:/Images/jc.jpg";  
6.     cv::Mat img = cv::imread(imagename);  
7.     if(img.empty())  
8.     {  fprintf(stderr, "Can not load image %s\n", imagename);  
9.         return -1;  
10.     }  
11.     if( !img.data )  
12.         return -1;  
13.     cv::namedWindow("image", CV_WINDOW_AUTOSIZE);  
14.     cv::imshow("image", img);  
15.     cv::waitKey();  
16.     return 0;  
17. } //(代码来自http://blog.sina.com.cn/s/blog_68ed8b21010163uc.html)  

     运行效果如下
