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

 1 #include "mainwindow.h"
 2 #include "ui_mainwindow.h"
 3 
 4 #include <opencv2/core/core.hpp>
 5 #include <opencv2/highgui/highgui.hpp>
 6 #include <opencv2/imgproc/imgproc.hpp>
 7 
 8 using namespace cv;
 9 
10 MainWindow::MainWindow(QWidget *parent)
11     : QMainWindow(parent)
12     , ui(new Ui::MainWindow)
13 {
14     ui->setupUi(this);
15 
16     cv::Mat image = imread("D:\\2.jpg");
17     namedWindow("Display window",WINDOW_AUTOSIZE);
18     imshow("Display window",image);
19     waitKey(0);
20 }
21 
22 MainWindow::~MainWindow()
23 {
24     delete ui;
25 }

添加按钮后代码，可点击按钮打开图片

 1 #include "mainwindow.h"
 2 #include "ui_mainwindow.h"
 3 
 4 #include <QFileDialog>
 5 #include <QMessageBox>
 6 #include <QPixmap>
 7 
 8 #include <opencv2/opencv.hpp>
 9 #include <opencv2/imgproc.hpp>
10 
11 using namespace cv;  // 引入opencv的命名空间
12 using namespace std;
13 
14 MainWindow::MainWindow(QWidget *parent)
15     : QMainWindow(parent)
16     , ui(new Ui::MainWindow)
17 {
18     ui->setupUi(this);
19 }
20 
21 MainWindow::~MainWindow()
22 {
23     delete ui;
24 }
25 
26 void MainWindow::on_pushButton_clicked()
27 {
28     QString filename = QFileDialog::getOpenFileName(this, "打开图像文件", "C:/Users", "Image Files (*.bmp;*.png;*.jpg)");
29 
30     if (filename.isEmpty()) {
31         QMessageBox::information(this, "提示", "文件打开失败1!");
32         return;
33     }
34     Mat img_input;
35     img_input = imread(filename.toLocal8Bit().toStdString());
36 
37     if (img_input.empty()) {
38 
39         QMessageBox::information(this, "提示", "文件打开失败2!");
40         return;
41     }
42     cv::Mat temp;
43     cv::cvtColor(img_input, temp, cv::COLOR_BGR2RGB);
44 
45     namedWindow("Display window",WINDOW_AUTOSIZE);
46     imshow("Display window",img_input);
47     waitKey(0);
48 
49     MainWindow w;
50     w.show();
51 }

相对来说qt+mingw+opencv的路径就比较简单

1 #包含路径
2 INCLUDEPATH += E:\opencv\opencv4.5.4_mingw730_64_qt5.14.2\include
3 
4 #库文件
5 LIBS += E:\opencv\opencv4.5.4_mingw730_64_qt5.14.2\x64\mingw\lib\libopencv*.a
