Using OPENCV libraries in Qt Creator

Use OpenCV library in Qt creator (successful compilation under Windows 7 system)

Compiling OpenCV2.0

1 Download tdm-mingw-1.908.0-4.4.1-2 and install, install complete add bin to system path.

2 Installing Opencv2.0 Windows version

3 Installation CMake

4 Open CMake, configure source and target path, select MinGW makefiles, and generate target makefile

5 go to set target path, make until all libraries are generated

Configuring QT Creator

QT developed programs generally need to use Qmake to generate makefile files. Because Qmake does not recognize spaces when parsing paths, you need to ensure that OPENCV's installation path cannot contain spaces (C:\Program FILES\OPENCV is not possible).

When creating the project file (assumed to be hello.pro and suffix Pro), add the following statement to the project:

INCLUDEPATH　+=　　D:\Qt\OpenCV-2.0.0\include\opencv
LIBS　+=　　D:\Qt\OpenCV-2.0.0\lib\libcv200.dll.a\
　　　　　　　　 D:\Qt\OpenCV-2.0.0\lib\libcxcore200.dll.a\
　　　　　　　　 D:\Qt\OpenCV-2.0.0\lib\libml200.dll.a\
　　　　　　　　 D:\Qt\OpenCV-2.0.0\lib\libcvaux200.dll.a\
　　　　　　　　 D:\Qt\OpenCV-2.0.0\lib\libhighgui200.dll.a　

In this way, OPENCV 2.0 can be used in QT.
