Qt与OpenCV结合：图像显示

注意：为了防止min max 问题，要把opencv的包含放在包含列表的最后...

配置文件：自己替换即可.

INCLUDEPATH += C:/Dev/CV2.4.6/opencv/build/include

LIBS +=C:/Dev/CV2.4.6/opencv/build/x86/vc10/lib/opencv_highgui246d.lib

LIBS += C:/Dev/CV2.4.6/opencv/build/x86/vc10/lib/opencv_core246d.lib

LIBS += C:/Dev/CV2.4.6/opencv/build/x86/vc10/lib/opencv_imgproc246d.lib

cpp包含文件：

#include <QMainWindow>

#include <QTextEdit>

#include <QDockWidget>

#include <QWidget>

#include "draw/curveSimple.h"

#include "draw/sinusplot.h"

#include "draw/QwtDraw.h"

#include "draw/cruvePlot.h"

//#include <opencv/cv.h>

//#include <opencv2/core/core_c.h>

#include <opencv2/core/core.hpp>

#include <opencv2/highgui/highgui.hpp>

#include <opencv2/imgproc/imgproc.hpp>

使用控件显示图像的代码：

void CWishGUI::showCvRGB(cv::Mat &image)

{

//    //1.利用QPixmap显示图像

//    QPixmap pixmap("./Image/SunFlowerMicro.jpg");

//    this->ui->WishLabel->setPixmap(pixmap);

    //2.利用OpenCV显示图像//在Label上显示

    cv::Mat rgb;

    QImage img;

    if(image.channels()==3)  {

        //cvt Mat BGR 2 QImage RGB

        cvtColor(image,rgb,CV_BGR2RGB);

        img =QImage((const unsigned char*)(rgb.data),

                    rgb.cols,rgb.rows,

                    rgb.cols*rgb.channels(),

                    QImage::Format_RGB888);

    }

    else {

        img =QImage((const unsigned char*)(image.data),

                    image.cols,image.rows,

                    image.cols*image.channels(),

                    QImage::Format_RGB888);

    }

    this->ui->WishLabel->setPixmap(QPixmap::fromImage(img));

    this->ui->WishLabel->resize(ui->WishLabel->pixmap()->size());

    return;

}
