打开Qt项目中的.pro文件，添加如下代码

INCLUDEPATH +=D:\\OpenCV\\opencv\\build\include\\opencv2 \

D:\\OpenCV\\opencv\\build\include\\opencv \

D:\\OpenCV\\opencv\\build\include

CONFIG(release,debug|release)

{

    LIBS += D:\\OpenCV\\opencv\\build\\x86\\vc10\\lib\\opencv_calib3d231.lib \

}

CONFIG(debug,debug|release)

}

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 

using namespace std;

using namespace cv;

int main(int argc, char *argv[])

{

    QCoreApplication a(argc, argv);

    const char* imagename = ;

        //从文件中读入图像

        Mat img = imread(imagename);

        //如果读入图像失败

        if(img.empty())

        {

            fprintf(stderr, "Can not load image %s\\n", 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();

    return a.exec();

}
