opencv_contrib编译_opencv contrib编译

1.首先下载opencv_contrib源码
2.下载cmake-gui工具：http://www.cmake.org/cmake/resources/software.html
3.先编译opencv

4.第一次编译完成之后，我们需要将额外的opencv_contrib加到工程中进行第二次编译，在配置表中找到“OPENCV_EXTRA_MODULES_PATH”,设置其参数值为open_contrib源码包中的modles目录

先点配置，再点生成

Tips:有时opencv_ffmpeg.dll这个下载不下来，打开build目录下CMakeDownloadLog.txt，找到下载地址，放到浏览器手动下载，然后把下载的dll拷贝到
opencv\newcontribBuild\3rdparty\ffmpeg目录下，再进行编译就不会报错了。

还有boostdesc_bgm.i、boostdesc_bgm_hd.i、boostdesc_bgm_bi.i、boostdesc_bgm.i等文件下载不下来，解决方法同上，手动在浏览器打开看到源码，在下载的contrib里（不是生成的那个）opencv\opencv_contrib-3.4.2\modules\xfeatures2d下手动建立这四个文件，然后把源码复制进去就行

编译完成后，我们在资源管理器下查看上面设置的文件输出目录，发现目录下多出了很多文件，其实就是OpenCV.sln工程文件：

5.打开sln文件，先要选择生成项目
生成完之后

最后会有以下文件

6.打开VS属性管理器


1.VC++目录–>包含目录，添加：

D:\installFile\opencv\contribBuild\install\include

D:\installFile\opencv\contribBuild\install\include\opencv2

D:\installFile\opencv\contribBuild\install\include\opencv

2.VC++目录–>库目录，添加：
D:\installFile\opencv\contribBuild\install\x64\vc15\lib

3.链接器–>输入–>附加依赖项，添加： (下面添加的debug的版本，注意添加的库与编译选项要一致，需要注意debug比release的文件名多了个d)

opencv_bgsegm342d.lib

4.添加环境变量
D:\installFile\opencv\contribBuild\install\x64\vc15\bin

注：有时需要重启电脑环境变量才会生效
