Qt_5_4_1_MSVC2013_OpenGL和opencv2.10

網上的教程說的都是mingw編輯器的qt版本，所以需要重新編譯opencv

其實使用MSVC編輯器的話，可以直接調用。

只需要在pro文件裏進行配置即可：

在pro寫上：

在mian函數裏面：
#include "widget.h"#include <QApplication>

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <QDebug>
using namespace cv;
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    Widget w;
    w.show();
    Mat image= imread("D:/1.bmp",0);
    if(!image.empty())
    {
        qDebug()<<"iscc";
        imwrite("D:/1_2.bmp",image);
    }
    else
    {
        qDebug()<<"is error";
    }
    return a.exec();
}

在使用過程中，有時候配置都正確，但是就是編譯不通過，

其實只需要把debug和release編譯的臨時文件全部刪除，重新編譯即可

下面直接把整個工程放出來
