A Trajectory-based Statistics and Tactics Analysis System for Table Tennis
G.H. Wu, Chun-Ho Hung, Hsuan-Wei Chen, Wei-Ta Chu · 2023
For table tennis videos, we develop a system to analyze and generate statistics based on ball trajectories. By a real-time ball detector, the ball trajectory is constructed based on the tracking by detection scheme. Landing points on the table are estimated. Based on moving direction and the sequence of landing points, three-stage analysis can be achieved. We also analyze how a point starts (serving type classification) and how a point ends (point loss classification).
