最简单测试代码，不加按钮，启动后直接读取硬盘上一张图片

#include "mainwindow.h"
#include "ui_mainwindow.h"

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>

using namespace cv;

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    cv::Mat image = imread("D:\\2.jpg");
    namedWindow("Display window",WINDOW_AUTOSIZE);
    imshow("Display window",image);
    waitKey(0);
}

MainWindow::~MainWindow()
{
    delete ui;
}

 

添加按钮后代码，可点击按钮打开图片

#include "mainwindow.h"
#include "ui_mainwindow.h"

#include <QFileDialog>
#include <QMessageBox>
#include <QPixmap>

#include <opencv2/opencv.hpp>
#include <opencv2/imgproc.hpp>

using namespace cv;  // 引入opencv的命名空间
using namespace std;

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);
}

MainWindow::~MainWindow()
{
    delete ui;
}

void MainWindow::on_pushButton_clicked()
{
    QString filename = QFileDialog::getOpenFileName(this, "打开图像文件", "C:/Users", "Image Files (*.bmp;*.png;*.jpg)");

    if (filename.isEmpty()) {
        QMessageBox::information(this, "提示", "文件打开失败1!");
        return;
    }
    Mat img_input;
    img_input = imread(filename.toLocal8Bit().toStdString());

    if (img_input.empty()) {

        QMessageBox::information(this, "提示", "文件打开失败2!");
        return;
    }
    cv::Mat temp;
    cv::cvtColor(img_input, temp, cv::COLOR_BGR2RGB);

    namedWindow("Display window",WINDOW_AUTOSIZE);
    imshow("Display window",img_input);
    waitKey(0);

    MainWindow w;
    w.show();
}

 相对来说qt+mingw+opencv的路径就比较简单

#包含路径
INCLUDEPATH += E:\opencv\opencv4.5.4_mingw730_64_qt5.14.2\include

#库文件
LIBS += E:\opencv\opencv4.5.4_mingw730_64_qt5.14.2\x64\mingw\lib\libopencv*.a
