Robust electronic scoring analysis system for recreational and professional taekwondo sports

目前跆拳道比赛中使用的保护记分系统(PSS)存在许多缺陷。它们没有考虑到跆拳道的所有技术，因此鼓励运动员只表演系统认可的基本和重复的跆拳道技术。这种缺乏战斗性的创造力降低了参与度和观众收视率。由于这些设备的限制，整个行业都受到了影响。20/20 Armor寻求通过鼓励全球积极参与的新颖计分系统重振跆拳道产业。主要目标是通过在胸罩和头盔中安装高性能的冲击传感器来改进PSS。为此，研制了一种能够测量冲击能量的泡沫压电式传感器。其目的是开发一种系统，对所有类型的影响进行分类和评估，以便显示影响比例分数。事实上，传感器读数的数字信号处理和分析是检测和分类影响的基础。将开发能够提供对传感器信号的稳健分析的信号处理方法，以消除噪声和干扰，并提供有效的模式分类框架。

Current Protector Scoring Systems (PSS) used in Taekwondo have many drawbacks. They do not account for all Taekwondo techniques, thereby encouraging athletes to perform only basic and repetitive Taekwondo techniques which are recognized by the system. This lack of combative creativity has decreased participation and spectator viewership. Due to these equipment limitations, the industry suffers as a whole. 20/20 Armor seeks to revive the Taekwondo industry through a novel scoring system which encourages active global participation. The main objective is to improve the PSS by implementing a high performance impact sensor within the chest protector and headgear. A piezoelectric foam sensor capable of measuring impact energy has been developed for this purpose. The aim is to develop a system which classifies and assesses all types of impact in order to display an impact-proportional score. Indeed, digital signal processing and analysis of sensor readings is fundamental to the detection and classification of impacts. Signal processing methods capable of providing robust analysis of sensor signals will be developed to remove noise and interferences, and to provide efficient pattern classification framework.
