Setting Up OpenCV

• Follow the installation guide:

– http://opencv.willowgarage.com/wiki/InstallGuide

• Or, we’ll go through an example installation for Windows and Visual Studio.

Install OpenCV

• Download and Install OpenCV 2.0 from

– http://opencv.willowgarage.com/wiki/

• If it is a lab machine, it will say C:\Users\duhao\Documents\OpenCV2.0 Keep that in mind as the basepath for later use.

Install CMake

• Download & Install CMake2.8.0 binary distribution from

– http://www.cmake.org/cmake/resources/software.html

Build the OpenCV package

• Step 1:

– Start Menu -> Run -> cmd.exe

• C:\Users\xxxxx>cd \OpenCV2.0

• C:\OpenCV2.0>mkdir release

• C:\OpenCV2.0>cd release

• C:\OpenCV2.0\release>"\Program Files\CMake 2.8\bin\cmake" -D:CMAKE_BUILD_TYPE=RELEASE C:\OpenCV2.0

Build the OpenCV package

• Step 2:

– Open at C:\OpenCV2.0\release using Visual Studio

– Build a version.

Ready to Roll

• INCLUDES: – C:\OpenCV2.0\include\opencv

• E.g. cv.h cvaux.h cxcore.h highgui.h

• LIBS: – C:\OpenCV2.0\release\lib\Release

• E.g. cv200.lib cvaux200.lib cxcore200.lib highgui200.lib

• DLLS: – C:\OpenCV2.0\release\bin\Release

• E.g. cv200.dll cvaux200.dll cxcore200.dll highgui200.dll

Starting a VC++ Project

• File -> New -> Project

Adding PATHS : INCLUDES • Right click project name -> Property

Adding PATHS : LIBS

Adding LIB Files

DLLS

• Copy all DLLS at C:\OpenCV2.0\release\bin\Release to a BIN path, for example C:\Windows\System32

• or copy them to the same path as your .EXE file.
