在Qt中搭建OpenCV的运行环境

为了在Qt环境中搭建OpenCV，本人安装了如下软件

• OpenCV2.3.1
• Qt 4.6.2
• QtCreator 2.8.1

在操作系统配置系统环境变量

Path = C:\Qt4.6.2\bin; C:\Qt4.6.2\include; D:\OpenCV23\build\x86\vc9\bin;

在QtCreator创建Qt控制台程序，工程名为OpenCV

编辑OpenCV.pro

QT += core

QT -= gui

TARGET = OpenCV
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app

SOURCES += main.cpp

# Add OpenCV include directory
INCLUDEPATH += D:\OpenCV23\build\include\
# Add OpenCV library direcotry and library files
LIBS += -LD:\OpenCV23\lib\build\x86\vc9\lib\
-lopencv_core231d \
-lopencv_imgproc231d \
-lopencv_highgui231d \
-lopencv_legacy231d

编辑main.cpp文件

#include <QCoreApplication>

#include <opencv/cv.h> // Load opencv Library
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>

using namespace cv; // Load cv namespace
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    Mat image = imread("lena.jpg"); // Load image
    namedWindow("OpenCV"); // Name window
    imshow("OpenCV",image); // Show image
    waitKey(0); // Keep image show alway
    return a.exec();
}

把需要显示的图片放到指定的Debug或Release文件夹，编译运行

如果编译通过，但运行时不能正常显示图片，如以下结果，请确认已经将图片放入正确路径。
