QT5.9.3安装及编译&与vs2013环境配置&opencv配置及调用

初次使用QT,安装时就遇到了一些问题,调试加整理文件用了三天,现在总结出来,希望有所帮助。

 

最终选择版本:

Windows7+Qt5.9.3(包含QtCreator4.4.1)+VS2013+OpenCV3.3.0+cmake3.10.0

一、        Qt及QtCreator的下载与安装

在资源下载页面(http://download.qt.io/archive/qt/)进行下载,这里罗列了多有可用版本,便于选择。根据自己的开发需要,我们这里下载的版本是:qt-opensource-windows-x86-5.9.3.exe

二、        QT安装

运行qt-opensource-windows-x86-5.9.3.exe,下一步即可;

Skip即可;

 

 QT5.9.3安装及编译&与vs2013环境配置&opencv配置及调用_第3张图片

直接点击下一步;

选择好安装文件夹,建议不要将QT安装在C盘,其他保持默认即可,点击下一步;

下一步是根据需要选择组件,相关的选择标准请参照链接:https://jingyan.baidu.com/article/656db918d9292ae380249c4f.html

我们这里勾选了MinGW及VS(msvc2013)相关的编译器;Tools全部进行了勾选。

接着,在打开的页面中勾选“我已阅读并同意条款”,然后一路下一步,直到安装完成就可以了。

等待至安装完成。

三、        三、QT creator打开与创建

安装好的QT5.9.3直接包含qt creator4.4.1在内,打开qt creator4.4.1。

点击ok。

新建项目进行编程操作即可。

四、        VS2013与opencv3.3.0配置

参考链接如下:

(1)http://blog.csdn.net/jinian2614/article/details/78176704

(2)为方便实现永久配置,配置OpenCV3.3动态链接库及以后的操作,参照第二个链接如下:

五、            QT5.9.3与opencv3.3.0配置

参考链接如下:

https://wiki.qt.io/How_to_setup_Qt_and_openCV_on_Windows (windows下QT5.9.3与opencv3.3.0配置)需要注意的的地方是,在configure cmake对opencv产生解决方案前,需将cmake的路径:D:\opencv\cmake-3.10.0-rc1-win64-x64\bin(才开始因解压时未注意,路径为D:\opencv\cmake-3.10.0-rc1-win64-x64\cmake-3.10.0-rc1-win64-x64\bin,当用此路径时,或许因路径过长,无法进行cmake configure

及MinGW的路径:D:\Qt\Qt5.9.3\5.9.3\mingw53_32\bin与D:\Qt\Qt5.9.3\Tools\mingw530_32\bin  这三个环境变量都添加至系统环境变量的path中,才能进行的了configure操作。其余详细参照以上链接操作即可。更改QT中文件代码如文件《opencv在QT中配置代码》,详细如下:


modify the .pro file like this:

#-------------------------------------------------

#

# Project created by QtCreator2017-03-05T12:30:06

#

#-------------------------------------------------

 

QT      += core gui

 

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

 

TARGET = opencvtest

TEMPLATE = app

 

# The following define makes yourcompiler emit warnings if you use

# any feature of Qt which as been markedas deprecated (the exact warnings

# depend on your compiler). Pleaseconsult the documentation of the

# deprecated API in order to know how toport your code away from it.

DEFINES +=QT_DEPRECATED_WARNINGS

 

# You can also make your code fail tocompile if you use deprecated APIs.

# In order to do so, uncomment thefollowing line.

# You can also select to disabledeprecated APIs only up to a certain version of Qt.

#DEFINES +=QT_DISABLE_DEPRECATED_BEFORE=0x060000   # disables all the APIs deprecated before Qt 6.0.0

 

 

SOURCES += main.cpp\

       mainwindow.cpp

 

HEADERS += mainwindow.h

 

FORMS   += mainwindow.ui

 

 

 

INCLUDEPATH+=D:\opencv\OpenCV_QT\install\include     #注意该路径为编译后install内的路径,且该路径不能有空格,不能写错,要仔细

 

LIBS+=D:\opencv\OpenCV_QT\bin\libopencv_core330.dll

LIBS+=D:\opencv\OpenCV_QT\bin\libopencv_highgui330.dll

LIBS+=D:\opencv\OpenCV_QT\bin\libopencv_imgcodecs330.dll

LIBS+=D:\opencv\OpenCV_QT\bin\libopencv_imgproc330.dll

LIBS+=D:\opencv\OpenCV_QT\bin\libopencv_features2d330.dll

LIBS+=D:\opencv\OpenCV_QT\bin\libopencv_calib3d330.dll

 

# more correct variant, how setincludepath and libs for mingw

# add system variable:OPENCV_SDK_DIR=D:/opencv/build

# read http://doc.qt.io/qt-5/qmake-variable-reference.html#libs

 

#INCLUDEPATH += $$(OPENCV_SDK_DIR)/include

 

#LIBS +=-L$$(OPENCV_SDK_DIR)/x86/mingw/lib \

#       -lopencv_core320        \

#       -lopencv_highgui320     \

#       -lopencv_imgcodecs320   \

#       -lopencv_imgproc320     \

#       -lopencv_features2d320  \

#       -lopencv_calib3d320

and modify mainwindow.cpp like this:(测试代码)

#include "mainwindow.h"

#include "ui_mainwindow.h"

 

#include

#include

 

MainWindow::MainWindow(QWidget*parent) :

   QMainWindow(parent),

   ui(new Ui::MainWindow)

{

   ui->setupUi(this);

 

    // read an image

   cv::Mat image = cv::imread("d://1.jpg", 1);

    // create imagewindow named "My Image"

   cv::namedWindow("My Image");

    // show theimage on window

   cv::imshow("My Image", image);

}

 

MainWindow::~MainWindow()

{

    delete ui;

}


笔者因为粗心,在前面.pro文件中的

INCLUDEPATH+=D:\opencv\OpenCV_QT\install\include    路径中复制入了空格,运行时始终提示opencv2/core/core.hpp...NO such file 等信息,无法运行成功,一定要仔细。
