Getting started

Download

  • Navigate to the repository
  • On the landing page select your desired OpenCV version

Or use following release table

Version Build-Info All Build-Configurations Examples
4.12.0 ( latest) link
4.11.0 link
4.10.0 link
4.9.0 link
4.8.0 link
4.7.0 link
4.6.0 link
4.5.5 link
4.5.4 link

The precompiled libraries are attached as assets compressed in zip archives to the bottom of the page.

Please check the Build-Info for the included OpenCV modules

Success

  • Downloaded one or more archives e.g.: MSVC142_64.zip.
  • Downloaded the corresponding Examples.zip of the release.

Unpack the archives

If you completed the task, proceed as follows to this project setup

.

Build Examples

The project setup

Place for holding the Visual Studio Examples source code is following git repository

In every directory there is solution file with Examples_<vs_compiler_name>.sln and other directories holding the wanted examples, required project, configuration and resource files. For e.g. vs2019 the directory-file-tree looks like that

.
├─ vs2019/
│  ├─ 0_HelperScripts/*                  # Contains required helper projects e.g. copying files
│  ├─ 1_Print_Version/*                  # Contains project files and source code for this example
│  ├─ 2_Image_Read_and_Display/*         # ~
│  ├─ 3_Image_Webcam_Read_and_Display/*  # ~
│  ├─ 4_Image_Webcam_Canny_Detection/*   # ~
│  ├─ OpenCV_PropertySheet/*             # Contains the property sheet for easy including the required compile and linking dependencies
│  ├─ res/*                              # Contains required files for specific examples.
│  └─ Examples_vs2019.sln                # The solution file including and organizing all the example projects

Using Visual Studio IDE

Please make sure that you have the correct/any build tools installed.

Open the Examples_<vs_compiler_name>.sln with the required IDE version. If everything was correctly placed (unpacked), no error popup will appear 😜.

For further help checkout the FAQ or create an issue.

And it will look this snapshot using VS 2019 IDE. Image title

Click Examples_<vs_compiler_name> and choose Build Solution or simply use the shortcut Ctrl+Shift+B to build all examples.

Output Directory

The output layout follows this scheme 

.
└─ _out_/
   └─ <architecture>/              # x64 or x86
      └─ <build configuration>/    # Debug, Release or RelWithDebInfo
         └─ <All the examples>/*   # binares and ressources
