ubuntu下 qt+opencv 配置

首先,下载,安装和重新编译opencv,参考 http://blog.csdn.net/cc198877/article/details/7785384

其次,在qt中使用opencv有两种方式:

(1). 将opencv库添加到qt creator中(以后就不需要每次新建项目都要添加):

打开qmake.conf文件:   sudo gedit /usr/share/qt4/mkspecs/default/qmake.conf

添加以下代码(注意检查路径是否一致):

QMAKE_INCDIR = /usr/include/opencv  

QMAKE_LIBS = -lcvaux -lcv -lcxcore -lhighgui -lml 

(2). 将下面内容添加到你项目下的.pro文件里:

我的是opencv2.4.1,添加的内容如下:

INCLUDEPATH += /usr/local/include/opencv

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

/usr/local/lib/libopencv_highgui.so \

/usr/local/lib/libopencv_ml.so

之前的版本可能大概是下面这样,大家根据自己的路径自行修改:

INCLUDEPATH += /usr/local/include/opencv  

LIBS += /usr/local/lib/libcv.so \  

/usr/local/lib/libcvaux.so \  

/usr/local/lib/libcxcore.so \  

/usr/local/lib/libhighgui.so \  

/usr/local/lib/libml.so 

现在尝试一下编译应该就可以通过啦~
