Table Soccer Video Analysis with OpenCV in Python - Basler dart / pulse Camera connected with PyPylon

During my own websearch couple of weeks ago I found some impressive demonstrations of video analysis setups for table soccer matches. But sadly none of those mostly university groups have published their code.

So not that long ago I began coding an OpenCV based ball-detection as a first step realizing the project. It became clear pretty fast that I won't be able to do all of the coding by myself, so I decided to release the project to all of you already although there still is a lot of work to be done before the project could somehow be called as "finished".

I focused a lot on writing the project code in a as modular way as possible so it will be easy to adapt new awesome features you might want to add to it.

So here's what I've done for now

• Basic structure with clear separation between
  • camera interaction
  • several analyzing classes
  • a universal output class
• Ball tracking with automatic color calibration
• Field detection (orientation, scale, goal line, etc.)
• Goal detection and counting
• ball speed calculation in m/s
• Heatmap generation when a match is finished

Obviously there is plenty of work to do and probably you have even more great ideas what can be done for a great user experience. Here I some ideas which I would like to implement if I have enough time in the future.

• ball prediction for a faster ball detection
• Web-based user interface with a responsive design to be usable on any device with Bluetooth or wifi

TableSoccerCV is hopefully just the beginning of some great Open Source table soccer video analysis projects. I hope you find my code useful! Cheers, StudentCV

0.1 - PreRelease

You will need the following packages for python to get the code working:

• Python 3.4
• OpenCV 3.0
• PyPylon 1.0.5 Get it here
• NumPy
• Matplotlib

Want to contribute? Great!

The code itself is documented within the source code as much as possible. I'll also provide a short coding manual asap.

Feel free to add some great functionalities!
