在Visual Studio 2012中安装OpenCV

Question

我试图安装OpenCV以使用Visual Studio。我使用的是2012Pro版本，但我认为它应该与vs10相同。 我按照这个教程： http://docs.opencv.org/doc/tutorials/introduction/windows_visual_studio_Opencv/windows_visual_studio_Opencv.html#windows-visual-studio-how-to

我有一个解决方案只有一个项目和只有一个文件。出于测试目的，我使用了与本教程中相同的代码。

// Video Image PSNR and SSIM

我已经下载了2.4.3版本，我把它解压到C：\ BUILD \ 所以现在我有C：\ BUILD \ OpenCV的等等

在视觉物业经理工作室我去的Microsoft.Cpp.Win.32.user表，我改变了以下:(根据说教程和其他解决方案在这里堆栈overvlow）

在C/C++ - >一般我加入其他包含目录

C:\BUILD\opencv\modules\core\include\opencv2\core 
C:\BUILD\opencv\include\opencv 
C:\BUILD\opencv\include\opencv2 
C:\BUILD\opencv\build\include 
C:\BUILD\opencv\build\include\opencv2 
C:\BUILD\opencv\build\include\opencv 

在连接器 - >常规我附加库目录

C:\BUILD\opencv\build\x86\vc10\lib 

添加在连接器 - >输入 - >附加依赖

（是的，我知道关于调试的d。但是，无论是工作）

我试图以类似的看问题，在这里，但所有的解决方案来增加实际的库添加到Addicionl依赖。我做了什么。所以我不知道...

Answer 1

您是否已将OpenCv路径添加到您的环境详细信息中？这通常是大多数教程告诉你要做的第一步。

但是，如果这不起作用，这是link，我总是用它来帮助我设置它。它使用的是VS 2012和OpenCV 2.4.3的版本，因此它与您的问题非常相似。
