Swimming Attitude for Tracking Error Correction Based on Mahony Algorithm
Mobile Information Systems, Volume 2022, Issue 1, 2022., 2022 Swimming is predominantly a long‐distance endurance sport. In this sport, like in many others, monitoring and tracking swimming attitude error correction and how it changes over time is critical. Besides, in swimming posture measurement, due to the absorption and refraction of various signals of water, sensors relying on external information cannot ...
