OpenCV3.0丢失Nonfree模块

1 原因：

with opencv3.0, SURF/SIFT and some other things have been moved to a seperate [opencv\_contrib repo][opencv_contrib repo] .

**在opecv3.0中，SURF/SIFT 以及其它的一些东西被移动到了独立的库(opencv\_contrib repo)中**

2 解决方法

you will have to download that, add it to your main opencv cmake settings (please look at the readme there), and rerun cmake/make.

then:

**你必须先下载opencv\_contrib repo （地址：[https://github.com/itseez/opencv\_contrib/][opencv_contrib repo]），然后把它添加到你的opencv cmake的设置中，然后运行cmake和make。**

#include "opencv2/xfeatures2d.hpp" ... Ptr<SIFT> sift = cv::xfeatures2d::SIFT::create(...); sift->detect(...);

3 编译方法

引自：[http://segmentfault.com/a/1190000003496009][http_segmentfault.com_a_1190000003496009]

# 一、下载安装 #

*  OpenCV3.0下载地址：[http://sourceforge.net/projects/opencvlibrary/files/opencv-win/3.0.0/][http_sourceforge.net_projects_opencvlibrary_files_opencv-win_3.0.0]
 *  OpenCVcontrib下载地址：[https://github.com/Itseez/opencv][https_github.com_Itseez_opencv]contrib
 *  cmake-gui下载地址：[http://www.cmake.org/cmake/resources/software.html][http_www.cmake.org_cmake_resources_software.html]

下载以上内容并安装opencv和cmake-gui，我的OpenCV安装路径为D:\\opencv3

# 二、使用cmake生成OpenCV.sln #

1.  打开cmake-gui
2.  在where is the source code选择opencv的安装目录，我的是D:\\opencv3\\opencv\\sources
3.  在where to build the binaries里面选择要将opencv编译到的目录下面，我的是：D:\\opencv3\\opencv\\mybuild
4.  点击configure，在弹出的对话框内选择 Visual Studio 2013和default参数，点击finish。
5.  这个时候cmake会开始编译不知道什么东西，然后会在屏幕中间出现一堆参数包括Name和Value，在其中找到Name为OPENCVEXTRAMODULESPATH的参数，然后把它的Value设置为opencvcontrib的路径，我的是D:/Files/Codes/Tracking/Exp/opencvcontrib-master/opencvcontrib-master/modules
6.  然后点击Generate，等待。中间报了两次错，我去掉了BUILDopencvadas和WITH\_CUDA等一系列看起来没用的东西，然后就完成了。

# 三、用VS编译生成debug和release库 #

1.  打开D:\\opencv3\\opencv\\mybuild目录下的OpenCV.sln
2.  编译debug版本库：在“解决方案'OpenCV'（141个项目）”上面点击右键-->重新生成解决方案。
3.  找到CMakeTargets中的INSTALL，然后右键选择“仅限于项目”-->“仅生成INSTALL”，然后就在D:\\opencv3\\opencv\\mybuild\\install中发现了许多东东。

# 四、重新配置自己的项目 #

1.  VC++目录-->包含目录，添加：  
    D:\\opencv3\\opencv\\mybuild\\install\\include
2.  VC++目录-->库目录，添加：  
    D:\\opencv3\\opencv\\mybuild\\install\\x86\\vc12\\lib  
    D:\\opencv3\\opencv\\mybuild\\install\\x86\\vc12\\staticlib
3.  链接器-->输入-->附加依赖项，添加：
