For the past few years, together with another Ph.D. student Michał Kopania we have built an instant review system for badminton. The system uses 14 to 20 fast cameras to track flying shuttlecock and detect when and where it landed on the floor of a court. Players may challenge the decisions of line judges when they do not agree with IN/OUT decisions.
We used our system in many tournaments. The biggest one was Badminton World Senior Championships in 2019.
To build such a system, we did quite a lot of research in the computer vision area and also invented our algorithms.
Last year we prepared a paper: "Real-time flicker removal for fast video streaming and detection of moving objects" it is now in the second round of a review process. We offer the system commercially, but we are still working on improving it. Now we concentrate on a better algorithm to detect the exact frame at which a shuttlecock hits the ground. We plan to write a paper this year describing our experiments and our method combining neural network working on sequences of raw frame patches and an ML model analyzing parameters from our trajectory approximation algorithm.
