Using Hybrid Sensoring Method for Motion Capture in Volleyball Techniques Training

摘要

The objective of the research is to provide a new hybrid motion capture method to assist the players' training of the standardized volleyball techniques. The proposed method is developed by integrating the optical passive maker based motion capture method and the non-optical inertial motion capture method. The hybrid method can accurately capture an individual volleyball player's movement including running, jumping, strike, service, reception, etc. Then, the captured motion data can be used to precisely reconstruct the player's behavior as a 3D model in the analysis system for the comparison between the player's volleyball techniques with the world-class players. Thus, the coach and the player can distinctly observe the degree of standardization of the player's volleyball techniques and improve the techniques by using the specific training methods. The hybrid motion capture method is proposed by exploring of the complementary characteristics of the optical and non-optical motion capture method. We verify the effectiveness of the proposed method by testing in the Sichuan Provincial Men's/Women's Volleyball Team and the local volleyball teams. The results of the research and test demonstrate that the proposed hybrid motion capture method is specifically suitable for assisting the training of the player's standardized volleyball techniques and significantly enhance the performance of the training.
