系统： windows xp

QT IDE：QT Creator5.1.1

OpenCV版本：OpenCV2.46

QT编译：Desktop_Qt_5_1_0_MSVC2010_32bit

OpenCV+VS+QT环境搭建：OpenCV2.4.5 + QT4.8.4 + VS2010 环境搭建

QT5.1.0 安装：VS2010+QT5.1+opencv2.4.5图像界面第一个程序

（1）修改Pro文件

#-------------------------------------------------
#
# Project created by QtCreator 2014-03-14T23:38:41
#
#-------------------------------------------------
QT       += core
QT       -= gui
TARGET = TestOpencv1
CONFIG   += console
CONFIG   -= app_bundle
TEMPLATE = app
SOURCES += main.cpp
INCLUDEPATH += C:\OpenCV_2.4.6\build\include\
INCLUDEPATH += C:\OpenCV_2.4.6\build\include\opencv\
INCLUDEPATH += C:\OpenCV_2.4.6\build\include\opencv2\


CONFIG(debug,debug|release) {
LIBS += -LC:\OpenCV_2.4.6\build\x86\vc10\lib \
    -lopencv_core246d \
    -lopencv_highgui246d \
    -lopencv_imgproc246d \
    -lopencv_features2d246d \
    -lopencv_calib3d246d
} else {
LIBS += -LC:\OpenCV_2.4.6\build\x86\vc10\lib \
    -lopencv_core246 \
    -lopencv_highgui246 \
    -lopencv_imgproc246 \
    -lopencv_features2d246 \
    -lopencv_calib3d246
}

（2）main.cpp的函数修改为

#include <opencv2\core\core.hpp>
#include <opencv2\highgui\highgui.hpp>
using namespace cv;

int main()
{
    //read a image
    Mat image= imread("img.jpg");
    // avoid mem error
    if (image.empty()){
        namedWindow("can not find image : img.jpg");
        waitKey();
        return -1;
    }
    //creat image windows named "My Image"
    namedWindow("My Image");
    //show the image on window
    imshow("My Image",image);
    //wait key for 5000ms
    waitKey(5000);

    return 1;
}

注意：

1.图片放置的目录为：C:\Users\daifeng\Documents\QT\build-TestOpencv1-Desktop_Qt_5_1_0_MSVC2010_32bit-Debug

2.qt5.1.1不用安装qmak(自带)。

第一次运行工程qmake不通过，重启电脑就OK啦~

或者新建一个工程，将源文件进行导入~
