对于Opencv的安装在网上有很多详细的教程，但是很多给出的配置是有问题的，这里以Open_cv 2.49+Windows 7(×64)+VS2013环境为例介绍Open_cv的安装：
首先下载Open_cv软件（选择2.4.9是因为国内很多教程仍然是以2.4.9为版本进行编辑的），这里也提供下载地址：Open_cv 2.4.9下载地址
首先是对Open_cv的安装，双击安装程序，选择安装路径，你可以自己选择，但是如果你从未安装过或者对配置环境变量等不熟悉，建议你复制和我一样的安装路径，后面会为你省很多麻烦：
D:\Program Files
等待解压：
打开VS新建项目，这块还是给各位简单的演示（熟悉的可跳过）：
首先是进行Debug属性的配置：
一、配置可执行文件目录
D:\Program Files\opencv\build\x86\vc12\bin
二、配置包含目录
这里需要填写三行：
D:\Program Files\opencv\build\include D:\Program Files\opencv\build\include\opencv2 D:\Program Files\opencv\build\include\opencv
三、配置库目录
D:\Program Files\opencv\build\x86\vc12\lib
四、配置附加依赖项
依赖项可以直接粘贴（注意不要粘贴错，和后面的Release版本是有区别的）
opencv_calib3d249d.lib opencv_contrib249d.lib opencv_core249d.lib opencv_features2d249d.lib opencv_flann249d.lib opencv_calib3d249.lib opencv_contrib249.lib opencv_core249.lib opencv_features2d249.lib opencv_flann249.lib opencv_gpu249.lib opencv_highgui249.lib opencv_imgproc249.lib opencv_legacy249.lib opencv_ml249.lib opencv_nonfree249.lib opencv_objdetect249.lib opencv_photo249.lib opencv_stitching249.lib opencv_ts249.lib opencv_video249.lib opencv_videostab249.lib opencv_gpu249d.lib opencv_highgui249d.lib opencv_imgproc249d.lib opencv_legacy249d.lib opencv_ml249d.lib opencv_nonfree249d.lib opencv_objdetect249d.lib opencv_photo249d.lib opencv_stitching249d.lib opencv_ts249d.lib opencv_video249d.lib opencv_videostab249d.lib
接下来是对Release的配置（这里步骤类似，只放一下，每一个地方要配置的内容）：
一、配置可执行目录
D:\Program Files\opencv\build\x86\vc12\bin
二、配置包含目录
D:\Program Files\opencv\build\include D:\Program Files\opencv\build\include\opencv2 D:\Program Files\opencv\build\include\opencv
三、配置库目录
D:\Program Files\opencv\build\x86\vc12\lib
配置完成后的示意图：
四、配置附加依赖项（注：千万别复制错，和Debug版本的不同）
opencv_calib3d249.lib opencv_contrib249.lib opencv_core249.lib opencv_features2d249.lib opencv_flann249.lib opencv_calib3d249.lib opencv_contrib249.lib opencv_core249.lib opencv_features2d249.lib opencv_flann249.lib opencv_gpu249.lib opencv_highgui249.lib opencv_imgproc249.lib opencv_legacy249.lib opencv_ml249.lib opencv_nonfree249.lib opencv_objdetect249.lib opencv_photo249.lib opencv_stitching249.lib opencv_ts249.lib opencv_video249.lib opencv_videostab249.lib opencv_gpu249.lib opencv_highgui249.lib opencv_imgproc249.lib opencv_legacy249.lib opencv_ml249.lib opencv_nonfree249.lib opencv_objdetect249.lib opencv_photo249.lib opencv_stitching249.lib opencv_ts249.lib opencv_video249.lib opencv_videostab249.lib
到这里，Open_cv就配置完成了，接下来我们验证是否配置成功：
新建一个CPP文件
输入以下代码：
#include<cv.h>
#include<highgui.h>
int main(int argc, char** argv[])
{
IplImage* src = cvLoadImage("psb.jpg"); //填入图片位置
cvNamedWindow("HeuLeaf", CV_WINDOW_AUTOSIZE);
cvShowImage("HeuLeaf", src);
cvWaitKey(0);
cvDestroyAllWindows();
return 0;
}
这里需要注意一点，路径一定将图片放入工程目录下，使用相对路径，使用绝对路径可能会出现显示不出图片内容的情况（打开的图像是灰色的），具体如下：
最后，图片被成功打开，配置完成：
