Installing and Using OpenCVMade to work with the following programs:1.2.3.4.OpenCV 2.3.1CMake 2.8TBB 4.0 08-09-2011Visual Studio 2010 Install OpenCVo Download OpenCV-2.3.1-win-superpack.exe. s/opencv-win/2.3.1/o Run the executable and install to “C:\OpenCV2.3”. NOTE: From this point, the root directory for OpenCV will be called" (CVROOT)”.o Open the new folder and the inside folder “opencv”. Cut all folders from inside“opencv” and move them back a folder to " (CVROOT)”. You can remove the opencvfolder.

Install TBBo Download TBB (Threading Building Blocks) http://threadingbuildingblocks.org/ver.php?fid 175.o Unzip the downloaded “TBB” to the directory “ (CVROOT)\build\common”.o Remove the “tbb” folder from “ (CVROOT)\build\common” folder.

o Rename the unzipped folder tbb. NOTE: From this point, “ (CVROOT)\build\common\tbb” will be called“ (TBBROOT)”Install CMakeo Download CMake .o Choose the option, “Add Make to the system PATH for all users”.

o If an error is returned, follow the special path addition under “Setting the pathvariables” section below.Setting the path variableso WARNING: Be careful when changing path variables. This can severely cripple yourcomputer if you delete the paths that are already in the list.o Go to the Start Menu and right click on “Computer”. Choose properties.o Go to “Advanced System Settings”.o Go to “Environment Variables”.o Under “System Variables” scroll and find Path. Choose Edit.

o Add the following paths to the end of the list. Remember between each path thereshould be a semicolon. C:\Program Files (x86)\CMake 2.8\bin (CVROOT)\build\x86\vc10\bin (TBBROOT)bin\ia32\vc10 IF CMAKE HAD AN ERROR: C:\Program Files (x86)\CMake 2.8\binRun CMake. This will create a library solution for OpenCV.o Locate the source code using the “Browse Source” Button. This is where you installedOpenCV or “ (CVROOT)”o Locate where you want to install the library using the “Browse Build” button. I used: “ (CVROOT)\Build”ooClick Configure to create the folders and files needed.It will ask for you to specify the generator for the project. Choose the version of VisualStudio that you are using.

oooClick FinishCheck the “BUILD EXAMPLES” option.Check the “WITH TBB” option.

oo Press Configure.Configure the “TBB INCLUDE DIR” option with the path to TBB,“ (CVROOT)/build/common/tbb/include”o Press Configure again.o Press Generate.Navigate to the “C:\OpenCV2.3\build” directory. Move through the list and find the “OpenCV”project solution file for Visual Studio.

Watch the bottom left side for messages. Wait to proceed until the messages stay a constant“Ready”.In Visual Studio, go to Build Build Solution to create the library. This may take some time. Youshould not get any failures.STARTING A PROJECT Open Visual StudioEither choose “New Project” on the welcome page, or go to File New ProjectChoose Win32 Console ApplicationName the project.Click OK.Click Next.

Choose the “Console application”.Uncheck the “Precompiled Header” option.

Click FinishUnder Solution Explorer, remove the following files (this step is not required):o stdafx.ho targetver.ho {name of project}.cppo stdafx.cppo ReadMe.txtUnder the Solution Explorer Source Files, right click and choose Add New Item.Make a C file with the name “main.cpp”.Under the Solution Explorer, right click the name of the project and choose Properties.Under C/C General add the following to “Additional Include Directories”:o (CVROOT)\build\include\opencvo (CVROOT)\build\include\opencv2o (CVROOT)\build\includeo (TBBROOT)\include\tbb

Under Linker General add the following to “Additional Library Directories”:o (CVROOT)\build\x86\vc10\libo (TBBROOT)\lib\ia32\vc10

Under Linker Input add any required libraries for the program you are making to “AdditionalDependencies”. If you do not know the name of the libraries, you can look in the (CVROOT)\build\x86\v10\lib\” Folder. The TBB libraries must be added.o opencv core231d.libo opencv highgui231d.libo opencv video231d.libo opencv ml231d.libo opencv legacy231d.libo opencv imgproc231d.libo opencv haartraining engined.libo opencv objdetect231d.libo tbb debug.libo tbb.libSetting up IP Webcam Install software for camera. This is useful for your own debugging purposes and connecting tothe camera to see if it works. You can use the software to also find the IP address for thecamera.Most cameras have a feed that you can watch in the following form.o "http://{Camera IP Address}/img/video.mjpeg"Use this address for file capturing in OpenCV. You can use the commandocapture o.mjpeg");
