跳台滑雪技术生物力学智能分析与反馈系统的研发与应用

An IntelligentMotion Capture and Feedback System Developed for Ski Jumping Technique Analysis

科技冬奥的一项重要任务就是利用高科技手段为运动员的科学训练提供帮助。在冰雪项目中,跳台滑雪运动具有运动范围大、运动速度快、飞行距离远的特点,对其进行三维生物力学运动分析存在一定的难度。研发团队融合数字视频识别的人工智能技术,基于超宽带(ultra wideband,UWB)的精准定位技术和加速度传感技术等多项高科技手段,开发了一套跳台滑雪动作技术分析与反馈生物力学系统,并在国家跳台滑雪队的日常训练中得到了应用。研究就该系统的构建原理和技术路线、模块功能及实际应用等方面进行分析。

Taking advantage of technological innovations to develop winter sports in China is an important task including using high-tech means to help athletes in their daily training.Ski jumping has the characteristics of fast movement speed and wide range,so the movement is difficult to be captured and analyzed.In this paper,the research and development team has integrated a number of high-tech methods,including artificial intelligence technology of digital video recognition,UWB based precise positioning and acceleration sensor,and developed a set of biomechanical system of movement analysis and feedback for the Chinese ski team.This study analyzes the construction prin-ciples,technical routes,module functions and practical application of the system.
