摘要
以普通摄像机拍摄得到的举重运动员的正侧面视频作为输入,通过一种改进的模板匹配算法跟踪杠铃中心轨迹,然后根据得到的杠铃中心位置计算举重运动中关键的技术参数,最后输出包括技术参数和曲线图的技术分析报告。实验结果证明,利用文中系统得到的结果准确可靠,已应用于举重运动的实际训练。
Given lifter＇s video acquired with an ordinary camera in lateral view, the trajectory of the barbell＇s center can be tracked automatically through an improved template matching algorithm. Key technical parameters are computed by the position of barbell＇s center and a technique analysis report consisting of parameters and graphs is created. Experiments show that tracking and analysis results are exact and reliable. This system has been applied to the practical training in weight lifting, to help analysis and improve the lifter＇s technique.
