在Qt Creator中使用OpenCV 2

然后，打开Qt项目中的.pro文件，添加如下代码

INCLUDEPATH+=D:OpenCVopencvbuildincludeopencv2

D:OpenCVopencvbuildincludeopencv

D:OpenCVopencvbuildinclude

CONFIG(release,debug|release)

{

LIBS+=D:OpenCVopencvbuildx86vc10libopencv_calib3d231.lib

D:OpenCVopencvbuildx86vc10libopencv_contrib231.lib

D:OpenCVopencvbuildx86vc10libopencv_core231.lib

D:OpenCVopencvbuildx86vc10libopencv_features2d231.lib

D:OpenCVopencvbuildx86vc10libopencv_flann231.lib

D:OpenCVopencvbuildx86vc10libopencv_gpu231.lib

D:OpenCVopencvbuildx86vc10libopencv_highgui231.lib

D:OpenCVopencvbuildx86vc10libopencv_imgproc231.lib

D:OpenCVopencvbuildx86vc10libopencv_legacy231.lib

D:OpenCVopencvbuildx86vc10libopencv_ml231.lib

D:OpenCVopencvbuildx86vc10libopencv_objdetect231.lib

D:OpenCVopencvbuildx86vc10libopencv_ts231.lib

D:OpenCVopencvbuildx86vc10libopencv_video231.lib

}

CONFIG(debug,debug|release)

{

LIBS+=D:OpenCVopencvbuildx86vc10libopencv_calib3d231d.lib

D:OpenCVopencvbuildx86vc10libopencv_contrib231d.lib

D:OpenCVopencvbuildx86vc10libopencv_core231d.lib

D:OpenCVopencvbuildx86vc10libopencv_features2d231d.lib

D:OpenCVopencvbuildx86vc10libopencv_flann231d.lib

D:OpenCVopencvbuildx86vc10libopencv_gpu231d.lib

D:OpenCVopencvbuildx86vc10libopencv_highgui231d.lib

D:OpenCVopencvbuildx86vc10libopencv_imgproc231d.lib

D:OpenCVopencvbuildx86vc10libopencv_legacy231d.lib

D:OpenCVopencvbuildx86vc10libopencv_ml231d.lib

D:OpenCVopencvbuildx86vc10libopencv_objdetect231d.lib

D:OpenCVopencvbuildx86vc10libopencv_ts231d.lib

D:OpenCVopencvbuildx86vc10libopencv_video231d.lib

}

注意，你的代码中的路径要根据OpenCV的具体安装路径做改变。

测试程序

#include

#include

usingnamespacestd;

usingnamespacecv;

intmain(intargc,char*argv[])

{

QCoreApplicationa(argc,argv);

constchar*imagename="E:\library\Pictures\lena.jpg";

//从文件中读入图像

Matimg=imread(imagename);

//如果读入图像失败

if(img.empty())

{

fprintf(stderr,"Cannotloadimage%sn",imagename);

waitKey();

return-1;

}

//显示图像

imshow("image",img);

//此函数等待按键，按键盘任意键就返回

waitKey();

returna.exec();

}

用Qt Creator编译时，要选择MSVC2010的发布编译器。
