Compiling BGSLibrary with OpenCV 3.x and Visual Studio 2015 from CMAKE

Dependencies

• OpenCV 3.x (tested with OpenCV 3.2.0)
• GIT (tested with git version 2.7.2.windows.1).
• CMAKE for Windows (tested with cmake version 3.1.1).
• Microsoft Visual Studio (tested with VS2015).

Step-by-step Instructions

Please follow the instructions below:

1. Go to Windows console.

2. Clone BGSLibrary git repository:

git clone --recursive https://github.com/andrewssobral/bgslibrary.git

3. Go to bgslibrary/build folder.

4. Set your OpenCV PATH:

setlocal
set OpenCV_DIR=C:\OpenCV3.2.0\build

5. Launch CMAKE:

cmake -DOpenCV_DIR=%OpenCV_DIR% -G "Visual Studio 14 Win64" ..

Now, you will see something like:

-- The C compiler identification is MSVC 19.0.24215.1
-- The CXX compiler identification is MSVC 19.0.24215.1
-- Check for working C compiler using: Visual Studio 14 2015 Win64

-- Found OpenCV 3.2.0 in C:/OpenCV3.2.0/build/x64/vc14/lib
-- You might need to add C:\OpenCV3.2.0\build\x64\vc14\bin to your PATH to be able to run your applications.
-- OpenCV library status:

--     include path: C:/OpenCV3.2.0/build/include;C:/OpenCV3.2.0/build/include/opencv
-- Configuring done
-- Generating done
-- Build files have been written to: C:/bgslibrary/build

6. Include OpenCV binaries in the system path:

set PATH=%PATH%;%OpenCV_DIR%\x64\vc14\bin

7. Open the bgs.sln file in your Visual Studio and switch to 'RELEASE' mode

7.1) Note: if the version of your Visual Studio is superior than 2015, you need to 'CANCEL' the project wizard update. However, you can go backward to step (5) and change the Visual Studio version, e.g.: -G "Visual Studio XX", where XX is your Visual Studio version.

8. Click on 'ALL_BUILD' project and build!

9. If everything goes well, you can run bgslibrary in the Windows console as follows:

9.1) Running BGSLibrary with a webcamera:

C:\bgslibrary> build\bgslibrary.exe --use_cam --camera=0

9.2) Running demo code:

C:\bgslibrary> build\bgs_demo.exe dataset/video.avi

9.3) Running demo2 code:

C:\bgslibrary> build\bgs_demo2.exe

Additional information:

• Note that bgslibrary requires a 'config' folder in the working directory.
