#### 下载Visual Studio ####

这里下载的是Visual Studio 2019，社区版(免费)即可  
下载地址 [https://visualstudio.microsoft.com/zh-hans/downloads/][https_visualstudio.microsoft.com_zh-hans_downloads]

#### 下载CMake ####

传送门: [https://cmake.org/download/][https_cmake.org_download]

Cmake安装教程详见 : [https://blog.csdn.net/u011231598/article/details/80338941][https_blog.csdn.net_u011231598_article_details_80338941]

#### 下载OpenCV源码 ####

下载opencv和opencv\_contrib(扩展)的源码  
git clone https://github.com/opencv  
git clone https://github.com/opencv/opencv\_contrib.git

#### 配置CMake ####

然后，点击`Configure`  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0V0aGFuQ28_size_16_color_FFFFFF_t_70 2]  
点击`Finish`，就会开始Cmake配置了  
配置完成后，会生成如下这样一个列表

我们搜索`extra`，在Value这栏填写上`opencv_contrib/modules`源码所在的路径  
**>>>>> 此处要注意 >>>>>>>>>>: 斜杠一定要用 /**

接着，我们再去点击`Configure`

> 需要注意 ippicv和ffmpeg等是否有编译失败的情况，如果有，请查看这篇博客解决 : [https://xugaoxiang.com/2019/12/26/build-opencv-with-cuda-for-windows/][https_xugaoxiang.com_2019_12_26_build-opencv-with-cuda-for-windows]

当出现`Configuring done`，我们检查下标红的日志，如果没有标红的日志了，那么就可以点击`Generate`按钮，生成VS的代码，生成完毕后，就可以点击 `Open Project`，使用VS打开项目了

找到CmakeTargets下的INSTALL选项，点击生成，然后就会正式开始编译了。

这个过程和硬件性能有关，有可能需要两个小时左右。  
接下来就慢慢等待编译完成即可 !  
`----------------------------------------------------------------`  
编译完成后，我们可以看多了一个install文件夹，里面有生成的dll等文件

至此，我们就完成了编译 !
