【开发技巧】VS2022+QT5+OpenCV4.10开发环境搭建QT Creator

VS2022编译器支持配置

QT5默认安装以后支持的是VS2015与VS2017，不支持VS2022，所以必须首先在Qt Creator中配置支持VS2022。配置顺序如下：

首先打开【工具】->【选项】
在这里插入图片描述
然点击Kits里面的【编译器】选项。点击Manual下面的【C++】然后点击【添加】

最重要的是填写好正确的VS2022编译器的路径，添加如下：

C:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Auxiliary\Build\vcvarsx86_amd64.bat

在这里插入图片描述
然后把VS2022编译器的路径添加到环境变量里面去：

C:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Tools\MSVC\14.42.34433\bin\Hostx64\x64

OpenCV4.10配置与代码测试

重启QT Creator，新建一个QApplication项目，选择MSVC2017 64bit Release。然后在mainwindow.cpp文件中添加下面一段代码

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <opencv2/opencv.hpp>
#include "QLabel"MainWindow::MainWindow(QWidget *parent): QMainWindow(parent), ui(new Ui::MainWindow)
{ui->setupUi(this);this->setWindowTitle("OpenCV4.10+QT5+VS2022 - OpenCV学堂");cv::Mat frame = cv::imread("D:/images/yige.png");cv::Mat rgb;cv::cvtColor(frame, rgb, cv::COLOR_BGR2RGB);QImage img = QImage(rgb.data, rgb.cols, rgb.rows, rgb.step, QImage::Format_RGB888);img = img.scaled(QSize(800, 500), Qt::KeepAspectRatio);QPixmap  pixmap;pixmap = pixmap.fromImage(img);// QPixmap  pixmap("D:/images/dannis.jpg");QLabel *image_label = new QLabel();image_label->setAlignment(Qt::AlignCenter);image_label->setStyleSheet("background-color:rgb(0, 0, 0);color:red");image_label->setPixmap(pixmap);this->setCentralWidget(image_label);}MainWindow::~MainWindow()
{delete ui;
}

配置好OpenCV库依赖添加到*.pro文件中去
