1下载openCV，

https://sourceforge.net/projects/opencvlibrary/files/opencv-win/

参考官网https://docs.opencv.org/master/d3/d52/tutorial_windows_install.html

本次以2.4.10为例，解压到D:\opencv2.4.10

2配置环境变量

D:\opencv2.4.10\build\x86\vc11
对应关系如图

3包含路径设置

视图-〉属性管理器-〉debug处右键属性-〉通用属性-〉vc++目录-〉包含目录

添加
D:\Program Files\opencv\build\include
D:\Program Files\opencv\build\include\opencv
D:\Program Files\opencv\build\include\opencv2 这三个目录。

4库目录设置

视图-〉属性管理器-〉debug处右键属性-〉通用属性-〉vc++目录-〉库目录
添加
D:\opencv2.4.10\build\x86\vc11\lib

5链接文件设置

D:\opencv2.4.10\build\x86\vc11\lib下19*2个lib文件添加

opencv_calib3d2410d.lib
opencv_contrib2410d.lib
opencv_core2410d.lib
opencv_features2d2410d.lib
opencv_flann2410d.lib
opencv_gpu2410d.lib

6动态链接文件

从D:\opencv2.4.10\build\x86\vc11\bin 把所有dll文件拷贝到
c:\Windows\System32（win操作系统是32位）
C:\Windows\SysWOW64（win操作系统是64位）

7测试代码

#include <opencv2\core\core.hpp>
#include <opencv2\highgui\highgui.hpp>
using namespace cv;

Mat img(300, 300, CV_8UC3);
img.setTo(Scalar(0, 255));
imshow("  Hello", img);

waitKey();

// 读入一张图片 放在cpp同目录下 或 image_dir='D:\\Docum
Mat img=imread("sample/1.jpg");
if (img.data !=NULL)
{
	// 在窗口中显示
	imshow("first img",img);

}
