Installing OpenCV for Windows

■ Download / install latest version

  • pencv.org/releases.html

> OPENCVDIR

  • Precompiled multi-architecture build tree

OPENCVDIR/build = BUILD − Architecture/IDE-specific* subtrees BUILD/x{64|86}/vc{14|15} = LOCAL

*vc14 | vc15 > Visual Studio 2015 | 2017

  • Build tree structure

Release | Debug configurations

− BUILD/include header files

*.h *.hpp

− LOCAL/lib static libraries

*.lib | *d.lib

− LOCAL/bin dynamic libraries

*.dll | *d.dll

Installing OpenCV for Windows

■ System configuration

  • If administration rights

− Open Windows Control panel | Système et Sécurité | Système − Open dialog Paramètres système avancés − Open dialog Variables d’environnement − Update PATH from list Variables système

► add LOCAL/bin

  • If no administration rights

− Go to directory x{64|86}/{Release|Debug} of your current Visual Studio solution tree

► copy LOCAL/bin/*.dll

Installing Visual Studio

■ Download Visual Studio 2017

  • 3 versions available

Community − Free − Targeted to students &

  • pen-source developers

− Modular, with a variety of supported languages & frameworks ► sufficient for standard use Professional | Enterprise − Commercial − Targeted to small | large teams/projects/firms − Extended | end-to-end solution

Configuring Visual Studio for OpenCV

■ Save all

► The resulting Visual Studio solution folder provides a template

which can used for developing your own OpenCV applications

  • Solution folder structure

AppName AppName.sln AppName AppName.vcxproj AppName.vcxproj.filters AppName.vcxproj.user x64 x64

Solution configuration file Project configuration files Built solution subfolders

Configuring Visual Studio for OpenCV

■ Instantiating the template

  • In Windows Explorer

− Create a copy of the template folder = NewApp

► rename solution & project configuration files accordingly ► delete built solution folders

NewApp NewApp.sln NewApp NewApp.vcxproj NewApp.vcxproj.filters NewApp.vcxproj.user

Solution configuration file Project configuration files

Configuring Visual Studio for OpenCV

■ Instantiating the template

  • Use a text editor to replace references to template AppName

by NewApp in configuration files − solution configuration = NewApp.sln

► section Project

Project("{8BC9CEB8-8B4A-11D0-8D11-00A0C91BC942}") = “NewApp", “NewApp\NewApp.vcxproj", "{E5E08792-BA04-4B4B-86AA-991FF5F578BF}“

− project configuration = NewApp.vcxproj

► XML tag RootNamespace

<RootNamespace>NewApp</RootNamespace>
