摘　　要：使用计算机跟踪球场中的运动员,得到每名运动员的时序位置信息,是研究其体能和技、战术特点,辅助教练员进行科学训练的关键技术。运动场景中的目标跟踪方法有其特殊性。介绍了运动员实时跟踪的软件结构,研究了球类比赛中目标跟踪的特征选择、状态转换和实现方法,并以足球为例进行试验。试验结果证明,对多名运动员进行跟踪,算法是鲁棒而快速的。对多名运动员进行跟踪时,每秒帧数(fps)可以达到30。The tracking by computer on athlete at training and competition and obtaining the position information of time and order of each player is the key technique of studying their physical fitness, technical and tactical character, assisting coach to do scientific training. The method of target tracking at sport ground has its unique character. This paper introduced the software structure of real time tracking on players, studied the feature selection of target tracking, observation equation and state equation. The result showed that the tracking was fast which could tracks multi-athlete at 30 fps.
