摘要

本研究的目的是探讨利用惯性传感器:加速度计和陀螺仪获取的数据来跟踪游泳运动中的运动学参数(纵向加速度、速度和俯仰角)是否可行。提出了“视频+惯性传感器”和“仅惯性传感器”相结合的视频数据分析方法来估计运动参数。推导了利用惯性传感器数据估计纵向加速度的公式，并提出了估计俯仰角变化的互补滤波器。基于惯性传感器的运动学参数与视频数据分析和电磁跟踪系统导出的参数进行了比较。

Video and inertial sensors based estimation of kinematical parameters in swimming sport

The purpose of this study was to investigate if tracking of kinematical parameters (longitudinal acceleration, velocity and pitch angle) in swimming sport is feasible using data acquired with inertial sensors: accelerometer and gyroscope. Video data analysis combined “video + inertial sensor” and “inertial sensors only” methods are presented for estimation of kinematical parameters. The equation for estimation of longitudinal acceleration from inertial sensors data is derived and complementary filter for estimation of pitch angle variation is proposed. The inertial sensor based kinematical parameters are compared with video data analysis and electromagnetic tracking system derived parameters.
