In this paper, we propose a method to track the grip of a golf swing by the use of a Kinect sensor and particle filter and a method to evaluate the swing trajectory using DP matching. Tracking a golf swing with only a Kinect sensor causes tracking of the grip to be difficult, since swing speed is typically fast, both arms overlap each other, and the grip usually becomes hidden behind the ...

Furthermore, tracking a golf swing with only a particle filter also causes tracking of the grip to be difficult, since tracking failure occurs when the color of the grip and swinger's arms is similar. Therefore, by using skeleton information output by a Kinect sensor, we divided the poses of a golf swing into four stages. For each stage, we tracked the exact grip position by changing the tracking method. We also evaluated the swing trajectory using DP matching.
