AI Technical Summary
Existing ball positioning systems struggle to balance ease of deployment, calibration efficiency, and trajectory reconstruction quality, resulting in cumbersome deployment, time-consuming calibration, and high data transmission pressure, failing to meet the requirements for rapid deployment, high-precision positioning, and trajectory reconstruction with minimal data volume.
A ball positioning system based on distributed beacons is adopted. It uses mobile distributed beacons and mobile base stations for self-calibration, and combines event-triggered motion data acquisition by inertial measurement units to generate continuous motion trajectories. Automatic calibration and high-precision positioning are achieved by constructing an N-ary distance equation system and a parabolic physical model.
It enables rapid deployment, automatic calibration, and high-precision positioning of sports ball positioning systems, while reducing data transmission volume and improving the system's versatility and practicality. It is suitable for training analysis and competition data statistics in various ball sports such as tennis, badminton, and table tennis.
