环境：Ubuntu 14.04LTS+Qt creator 3.2.2+Opencv2.4.9各种默认安装的

新建工程：

在.pro文件后面加上调用的opencv类库

QT       += core

QT       -= gui

TARGET = MyQtConsoleProjiect
CONFIG   += console
CONFIG   -= app_bundle

TEMPLATE = app


SOURCES += main.cpp
INCLUDEPATH += /usr/local/include \
                /usr/local/include/opencv \
                /usr/local/include/opencv2

LIBS += /usr/local/lib/libopencv_highgui.so \
        /usr/local/lib/libopencv_core.so    \
        /usr/local/lib/libopencv_imgproc.so

然后.cpp

#include<opencv2/core/core.hpp>
#include<opencv2/highgui/highgui.hpp>

using namespace cv;
int  main(int argc, char *argv[])
{
    Mat image = imread("lena.jpg");
    namedWindow("MyImage");
    imshow("MyImage", image);
    waitKey(0);
    return 0;
}

运行结果
