OpenCV3.4.0编译





  OpenCV文件编译及问题记录。


目前最新OpenCV官网发布最新版为3.4.0(2017年12月23日发布)。

OpenCV库使用方法

下载地址:https://github.com/opencv/opencv/releases/tag/3.4.0

https://sourceforge.net/projects/opencvlibrary/

法一:使用官方提供的已编译好的文件

优点:方便快捷
缺点:版本限制
选择opencv-3.4.0-vc14_vc15.exe,下载完成后可以直接打开解压,即可在自己的项目中直接使用。
具体步骤为:

  1. 配置环境变量
    打开电脑右键属性-高级系统设置-环境变量,Path中新增:E:\opencv\build\x64\vc14\bin,(此处为解压对应目录)。

  2. 引入相应头文件、库文件、链接库
    打开自己的工程,右键属性-配置属性-VC++目录-包含目录,新增:
    E:\opencv\build\include\opencv
    E:\opencv\build\include\opencv2
    E:\opencv\build\include

库目录,新增:
E:\opencv\build\x64\vc14\lib
(注意修改为你解压对应的目录)。

链接器-输入-附加依赖项,新增:
opencv_world340d.lib
点击确定即可。
至此所有准备工作就绪,可以愉快地编译自己的工程啦。

但想如此一劳永逸解决问题,需符合以下特点:你的VS版本是VC14(2015)或VC15(2017)。
另附几种对应关系:
Microsoft Visual Studio 6.0: VC6.0
Microsoft Visual Studio 2002: VC7.0
Microsoft Visual Studio 2003: VC7.1
Microsoft Visual Studio 2005: VC8.0
Microsoft Visual Studio 2008: VC9.0
Microsoft Visual Studio 2010: VC10.0
Microsoft Visual Studio 2012: VC11.0
Microsoft Visual Studio 2013: VC12.0
Microsoft Visual Studio 2014: VC13.0
Microsoft Visual Studio 2015: VC14.0
Microsoft Visual studio 2017: VC15.0

由于我使用VS2013,因此无法使用该方法。(当然,可以自行下载VS2015的运行库)。
我使用法二。

法二:自行编译

下载源码Source code并解压

下载CMake

下载地址:https://cmake.org/download/
选择相应操作系统版本,例如我选择Windows win64-x64 Installer。安装,打开bin\cmake-gui.exe。

使用CMake

在Where is the source code中选择OpenCV解压目录,如:E:/opencv-3.4.0/opencv-3.4.0。
一般可以在解压目录下新建一个build文件夹,用来存放编译生成的文件。
于是,在Where to build the binaries中填入该路径,如:E:/opencv-3.4.0/opencv-3.4.0/build。(也可自行选择路径)

点击Configure,选择所需环境,如:Visual Studio 12 2013。进入漫长的等待。
如果区域有红色出现,需再次点击Configure,直到全部变成白色。

第一次Configure后:

可以看到文本中记录了下载链接,于是在浏览器中复制上述链接,自行下载好这几个文件到文本指向的路径中。
比如:我缺的三个文件是:
opencv_ffmpeg.dll,需放到:E:/opencv-3.4.0/opencv-3.4.0/build/3rdparty/ffmpeg。
下载链接:https://raw.githubusercontent.com/opencv/opencv_3rdparty/66b1fed06cf3510235f367f96aa26da5cb234a15/ffmpeg/opencv_ffmpeg.dll
opencv_ffmpeg_64.dll,需放到:E:/opencv-3.4.0/opencv-3.4.0/build/3rdparty/ffmpeg。
下载链接:
https://raw.githubusercontent.com/opencv/opencv_3rdparty/66b1fed06cf3510235f367f96aa26da5cb234a15/ffmpeg/opencv_ffmpeg_64.dll
ippicv_2017u3_win_ia32_general_20170822.zip,注意:需在压缩包前加上文件的hash值,即压缩名变为hash值-原名。提供一个在线查看哈希值的网站:http://www.atool.org/file_hash.php ,需要的是MD5 Hash。
需放到:E:/opencv-3.4.0/opencv-3.4.0/build/3rdparty/ippicv。(然而并没有生成ippicv文件夹)
下载链接:
https://raw.githubusercontent.com/opencv/opencv_3rdparty/dfe3162c237af211e98b8960018b564bc209261d/ippicv/ippicv_2017u3_win_ia32_general_20170822.zip
建议科学上网后下载,不然网速感人。
不过还是不匹配。

根据大佬提示,CMake3.10.2没有downloader.cmake,干脆……不要这三个文件了……

再重新Configure两次,Generate一次,成功。

用VS2013编译

打开OpenCV.sln编译,debug-Win32调试器。
