Ubuntu under QT configuration OpenCV

1. Install QT

$sudo Apt-get Install Qtcreator

2. Configure OpenCV

The OPENCV header and library files need to be associated with QT, so after double-clicking the Qtcreator project to the ***.pro file, add the following code after it:

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

That is, the corresponding entire ***.pro file at this time is as follows:

#-------------------------------------------------
#
Project created by Qtcreator 2012-07-09t22:01:34
#

qt =       core

qt-       = GUI

TARGET = Test1
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
