Robust Golf Club Tracking

Project Summary

The goal of this project was to elaborate a computer vision based method for the automatic tracking of golf clubs. It can provide additional information to the users such as club trajectory, speed and acceleration.

We developed a new visual tracking technology that relies on the use of a global motion model to achieve robustness. The challenging problem of retrieving the club head trajectory from ordinary video sequences of golf swings is a good application to demonstrate the effectiveness of this new approach. We have integrated it into a fully automated system that requires neither user intervention nor the use of instrumented golf club or clothing, and that is usable in a natural environment with a potentially cluttered background. Our algorithm robustly fits a global swing trajectory model to club location hypotheses obtained from single frames. This process makes our approach very robust.
