Measurement and Performance Evaluation of Lob Technique Using Aerodynamic Model in Badminton Matches

摘要

In badminton matches, lob is a special technique and can be classified into two categories: defensive and offensive. These lobs are difficult to quantitatively measure, analyze, and evaluate. In this paper, we propose a new aerodynamic model to estimate the 3D trajectory from a single camera video and evaluate the performance of lobs. The experimental results show that this model is reliable. Offensive lobs are easily identified by the height of the trajectory. Good lobs are placed farther from the opponent than the bad lobs.
