摘　　要：当前体育运动轨迹重构方法存在误差大、精度低等难题,为了改善体育运动轨迹重构效果,提出了基于红外传感技术的体育运动轨迹重构方法。首先采用红外传感技术采集体育运动轨迹信号,并对体育运动轨迹信号进行预处理,然后根据预处理后的体育运动轨迹信号得到动作轨迹位移,并根据这些信息得到各个方向上的瞬时速度与位移,从而实现体育运动轨迹重构,最后进行了体育运动轨迹重构仿真实验,结果表明,该方法可以高精度进行体育运动轨迹重构,而且体育运动轨迹重构结果可靠。At present,there are many problems in sports trajectory reconstruction,such as large error and low precision.In order to improve the effect of sports trajectory reconstruction,a sports trajectory reconstruction method based on infrared sensor technology is proposed.Firstly,the infrared sensor technology is used to collect the sports track signal,and the sports track signal is preprocessed.Then the motion track displacement is obtained according to the preprocessed sports track signal,and the instantaneous velocity and displacement in all directions are obtained according to the information,so as to realize the sports track reconstruction.Finally,the simulation experiment of sports track reconstruction is carried out The results show that this method can reconstruct the sports trajectory with high precision,and the reconstruction result is reliable.
