网球三维运动参数采集及技战术实时自动分析系统的运用研究

Study on the System of Tennis 3D(Three-Dimensional) Motion Parameter Collection and Technical and Tactical Real-time Automatic Analysis

借助高速摄像机,运用编成数据软件,对网球比赛录像相关数据进行记录、梳理,旨在研制一个网球三维运动参数采集及技战术实时自动分析系统。该系统具有扫描网球比赛中网球及运动员人体的三维运动轨迹及三维投影图,数字化同步重放、任意运动点及运动时段(或时刻)运动员动作图像,网球各项技战术统计、归整、分析,快速灵活查询运动员档案等功能,对运动员在网球比赛中技战术运用和策略制定提供直观的、科学的数据参考。

In order to manufacture a system of 3D motion parameter collection and technical and tactical real-time automatic analysis,this paper,with the aid of high speed camera and data programming software,records and cards the relevant data from tennis tournament videos.This system possesses the functions of portraying 3D movement locus and 3D skiagraph of both tennis ball and athletes＇ bodies,realizing digital synchronous replay,recording the athletes＇ movement pictures at random motor points or moments,analyzing,concluding and making statistics on tennis tactics and moves,and of inquiring the athletes＇ files quickly and flexibly.It can not be denied that these functions will provide the visual and scientific data reference for athletes to draw up and utilize their tactics in competitions.
