摘要:
为了探索网球比赛中鹰眼三维可视化技术实现原理,利用架设在网球场周围的多架高速摄像机获取网球运动的二维图像数据,经过多目摄像机帧同步、网球识别、球心坐标提取,再经过还原演算得到网球的空间三维坐标,然后对这些空间坐标进行曲线拟合以减小实际应用场景中产生的误差,同时解决球体遮挡问题。 利用 3D Max 搭建网球场地模型,并将其以 FBX 的格式导入 Unity3D 工程中,然后通过 Unity3D 平台挂载脚本,实时从数据库获取网球空间坐标,最后以交互式多视角的方式展示网球运动的三维场景。 结果表明:基于 Unity3D 开发的鹰眼三维可视化系统具有高度的可移植性及良好的兼容性,该系统能够以交互式的方式展示网球运动的三维场景,辅助裁判对于边界球的判罚,以及用于球队分析对手的击球方式和策略,提升网球比赛质量。
Abstract:
In order to explore the realization principle of hawk eye 3D visualization technology in tennis competition,? ? the two-dimensional image data of tennis movement is obtained by using several high-speed cameras set? ? up around the tennis court,and the three-dimensional coordinates of tennis space are obtained through calculation, which are curve-fitted and stored to reduce the error in the actual application scene and solve? ?the problem of sphere occlusion. The tennis court model is built by 3D Max and imported into Unity 3D project in the format of FBX. Then the script is mounted on Unity 3D platform to obtain the coordinates of tennis space from the database in real time.Finally,the 3D scene of tennis sport is displayed in an interactive multi- perspective way. The results show that the hawk eye 3D visualization system based on Unity 3D development with a high degree of portability and compatibility can display in the form of interactive 3D scene of tennis, auxiliary for boundary refereeing decisions and for the team analysis way of an opponent’s shot and strategy,improving the quality of the tennis match.
