本文详细介绍如何在QtCreator中配置并使用OpenCV库。包括设置工程文件中的链接及配置信息，以及OpenCV库函数的基本调用示例。通过本文，读者可以了解具体的配置步骤，并掌握基本的图像显示功能。

1

首先在Qt Creator的具体工程文件（*.pro）中，添加链接以及配置信息，如：

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

CONFIG(debug,debug|release) {
LIBS += -Ld:\opencv\build\x64\vc12\lib \
    -lopencv_core249d \
    -lopencv_highgui249d \
    -lopencv_imgproc249d \
    -lopencv_features2d249d \
    -lopencv_calib3d249d
} else {
LIBS += -Ld:\opencv\build\x64\vc12\lib \
    -lopencv_core249 \
    -lopencv_highgui249 \
    -lopencv_imgproc249 \
    -lopencv_features2d249 \
    -lopencv_calib3d249
}

OpenCV库函数的调用与在VS2013调用方式相同,如：

#include <QCoreApplication>
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <iostream>

using namespace cv;

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    cv::Mat src = imread("E:/Qt Project/opencv_demo/lena.png", CV_LOAD_IMAGE_ANYCOLOR);
    if(!src.data){
        std::cout << "Can't load the image." << std::endl;
        return false;
    }

    cv::namedWindow("Lena", WINDOW_AUTOSIZE);
    cv::imshow("Lena", src);

    cv::waitKey(0);
    return a.exec();
}
