**目录**

1、下载：

2、cmake

3.VS2015编译：

4.测试

--------------------

# 可以去我的资源下载编译好的库文件，省去自己编译的麻烦。 #

# 1、下载： #

**下载opencv源代码**  
源代码的地址是：[https://github.com/opencv/opencv/][https_github.com_opencv_opencv]

**下载opencv\_contrib源代码**  
opencv\_contrib代码地址是：[https://github.com/opencv/opencv\_contrib][https_github.com_opencv_opencv_contrib]

下载解压即可，**opencv和opencv\_contrib**版本号必须一致；

# 2、cmake #

1.  新建build文件夹
2.  打开cmake，链接source和build路径![20210331144714846.png][]
3.  Configure 两次，
4.  如果使用sift等非公开的特征算子，需要勾选nonfree选项；链接contrib模块路径，再次Configure，然后Generate

*  勾选

可以勾选opencv\_world选项让生成的dll文件只有opencv\_world一个，这样调用起来更加方便。

*  链接contrib模块路径

# 3.VS2015编译： #

打开工程Open Project;

直接编译运行的话，有可能报错

LINK : fatal error LNK1210: 已超过内部 ILK 大小限制；链接时使用 /INCREMENTAL:NO

此时，把opencv\_world项目属性页设置一下：![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3hkMTk4OTA5MjI_size_16_color_FFFFFF_t_70][]

然后单独对该项目生成项目，生成之后，生成ALL\_BUILD项目，然后生成install项目，在build/install即编译完成的文件；保存该文件夹，如果节省空间，其他文件都可以删了；配置工程时，链接build/install/include build/install/x64/vc14/lib文件夹即可，bin下是dll文件，将opencv\_world452d.dll这一个dll拷贝到工程目录，不需要其他很多的dll,因为cmake的时候勾选了![20210331150803228.png][]

选项，所以只需要这一个文件，方便快捷。
