第一步
安装 Visual Studio 2015 （废话），别忘了勾选C++部分组件
第二步
下载 OpenCV https://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.4.9/opencv-2.4.9.exe/download
第三步
运行 opencv-2.4.9.exe，解压到指定目录，这里我们解压到 C:\OpenCV2.4.9
第四步
设置环境变量，系统Path，加上，C:\OpenCV2.4.9\opencv\build\x86\vc12\bin
第五步
下载 Visual Studio 2013 的 debug 库，放到上一步的 bin 目录，http://pan.baidu.com/s/1dFIjbt3
第六步
创建 C++ Win32 控制台项目，复制粘贴以下测试代码，在 C:\\users\maxwell\pictures 目录创建图片文件 a.bmp
#include
#include
using namespace cv;
using namespace std;
int main()
{
Mat img = imread("C:\\\\users\\maxwell\\pictures\\a.bmp");
namedWindow("My Window");
imshow("iMy IMG, img);
waitKey(6000);
return 0;
}
第七步
设置项目属性
VC++目录->包含目录，C:\OpenCV2.4.9\opencv\include;C:\OpenCV2.4.9\opencv\include\opencv;C:\OpenCV2.4.9\opencv\build\include\opencv2
库目录，C:\OpenCV2.4.9\opencv\build\x86\vc12\lib
C/C++->命令行->其他选项，/D_CRT_SECURE_NO_WARNINGS
连接器->输入->附加依赖项，
