用传感器融合与AI实时识别跆拳道踢技,提升评分公平性和比赛观赏性。

AI-Driven Real-Time Kick Classification in Olympic Taekwondo Using Sensor Fusion

  • 融合多类传感器数据,通过机器学习实现踢技实时分类。
  • 96%-98%准确率验证了系统可行性,可区分踢击类型与发力部位。
  • 新评分规则激励动态进攻,适合赛事改革与体育科技研究者。

奥运跆拳道因静态防守和争议性判分导致观众参与度下降。现有防护与计分系统(PSS)依赖冲击传感器和简单逻辑,鼓励保守策略,削弱比赛活力。本文提出一种基于AI的计分系统,整合原有PSS传感器与额外加速度计、陀螺仪、磁/射频识别(RFID)及冲击力传感器,构建传感器融合框架,实现实时踢技分类,识别技术类型、击打位置、冲击力度甚至脚部接触部位。采用传感器融合与支持向量机(SVM)的机器学习流程,实现自动踢技识别。提出新型踢技评分标准,对转身、旋转等高难度动作加分,激励动态进攻。参考2024年研究中96%-98%的准确率,验证了实时分类的可行性,并建议使用集成SVM与扩展数据集以满足赛事高精度要求。分析表明该系统可提升评分公平性、减少规则滥用、鼓励高动态技术,增强观众理解与观赛兴奋感。论文包含系统设计图示、人工智能增强的踢技评分表,并讨论其对奥运跆拳道的潜在影响。

原文摘要 · Abstract (English)

Olympic Taekwondo has faced challenges in spectator engagement due to static, defensive gameplay and contentious scoring. Current Protector and Scoring Systems (PSS) rely on impact sensors and simplistic logic, encouraging safe strategies that diminish the sport's dynamism. This paper proposes an AI-powered scoring system that integrates existing PSS sensors with additional accelerometers, gyroscopes, magnetic/RFID, and impact force sensors in a sensor fusion framework. The system classifies kicks in real-time to identify technique type, contact location, impact force, and even the part of the foot used. A machine learning pipeline employing sensor fusion and Support Vector Machines (SVMs) is detailed, enabling automatic kick technique recognition for scoring. We present a novel kick scoring rubric that awards points based on specific kick techniques (e.g., turning and spinning kicks) to incentivize dynamic attacks. Drawing on a 2024 study achieving 96-98% accuracy, we validate the feasibility of real-time kick classification and further propose enhancements to this methodology, such as ensemble SVM classifiers and expanded datasets, to achieve the high-stakes accuracy required by the sport. We analyze how the proposed system can improve scoring fairness, reduce rule exploitation and illegitimate tactics, encourage more dynamic techniques, and enhance spectator understanding and excitement. The paper includes system design illustrations, a kick scoring table from an AI-augmented rule set, and discusses anticipated impacts on Olympic Taekwondo.
