The Prediction of Badminton Flight Trajectory Based on an Intelligent Compensator

A real-time visual servo badminton trajectory tracking system (VSBTTS) is proposed in this study. VSBTTS is composed of two parts: the image unit and the tracking operation unit. The primary function of the image unit is to segment the moving shuttlecock from a continuous image taken by the camera and detect the moving object. The tracking operation unit is used to track parts of the shuttlecock found in the image unit. Then, the flight trajectory of the shuttlecock is estimated; however, it is difficult for tracking operation units to avoid estimation errors, preventing them from achieving full accuracy. In this study, a fuzzy compensation controller is used to compensate for the system estimation errors of the flight trajectory. Using the fuzzy compensator, the trajectory of the shuttlecock is accurately estimated. Experimental results demonstrate the usefulness of the proposed shuttlecock trajectory tracking system.
