Python 版本的实现在这篇博客 ❤ o( ̄▽ ̄)d
https://blog.csdn.net/zuliang001/article/details/80882524
1.1 在用户变量里新建变量OpenCV,变量值:C:\SDK\opencv\build;
1.2 在用户变量的Path中添加:C:\SDK\opencv\build\x86\vc11\bin;
(另,在OpenCV配置中,vc11即对应VS2012,vc12对应的是VS2013。这里x86还是x64的选择跟你的电脑是32位还是64位无关,这里我使用vs2012编译环境为win32编译器,所以选择x86。)
1.3 在系统变量中的Path中也加上;
(另,要使用英文输入下的分号和前面已有的路径分开,添加完之后需要重启或注销计算机,环境变量才会生效。)
1.4 VS2012的工程项目属性配置
新建Win32控制台应用程序,工程名命名为MyFirstOpenCV,在其后的选项里选择空项目:
打开“属性管理器”,在属性管理器的Debug|Win32目录上右键单击选择“添加新项目属性表”,新建属性表,并命名为OpenCVDebug
双击打开属性表OpenCVDebug.props。选择通用属性->VC++目录,在包含目录里添加3个目录:
在VC++目录下,在库目录里添加1个目录:C:\SDK\opencv\build\x86\vc11\lib
选择通用属性->链接器->输入->附加依赖项,在附加依赖项里添加库文件:
opencv_ml2413d.lib
opencv_calib3d2413d.lib
opencv_contrib2413d.lib
opencv_core2413d.lib
opencv_features2d2413d.lib

cvNamedWindow("游戏原画");
// 在窗口中显示游戏原画
imshow("游戏原画",img);
// 等待6000 ms后窗口自动关闭
waitKey(6000);
}
###2. 海康SDK的配置
添加新项目属性表,设置海康威视sdk的属性,添加头文件、库文件、附加依赖项:

GdiPlus.lib

HCNetSDK.lib
HCAlarm.lib
HCGeneralCfgMgr.lib
