到目前为止，体育赛事的远程体验大多局限于观看视频以及与该项运动相关的比分和统计数据。然而，一个快速发展的趋势是利用可视化技术对运动员的表现、风格和策略提供新的见解。自动化技术能够从视频中提取有关运动员表现的准确信息，这些信息甚至是最熟练的观察者也无法辨别的。当以静态图像或三维虚拟回放的形式呈现时，这些信息使观看比赛成为一种全新且令人兴奋的体验。本文介绍了一个这样的体育可视化系统，名为朗讯视觉（LucentVision），它是为网球运动而开发的。朗讯视觉利用实时视频分析来获取运动员和球的运动轨迹，并基于这些轨迹数据提供了丰富的可视化选项。该系统已在国际网球锦标赛的电视和互联网转播中广泛使用。
Remote experience of sporting events has thus far been limited mostly to watching video and the scores and statistics associated with the sport. However, a fast-developing trend is the use of visualization techniques to give new insights into performance, style, and strategy of the players. Automated techniques can extract accurate information from video about player performance that not even the most skilled observer is able to discern. When presented as static images or as a three-dimensional virtual replay, this information makes viewing a game an entirely new and exciting experience. This paper presents one such sports visualization system called LucentVision, which has been developed for the sport of tennis. LucentVision uses real-time video analysis to obtain motion trajectories of players and the ball, and offers a rich set of visualization options based on this trajectory data. The system has been used extensively in the broadcast of international tennis tournaments, both on television and the Internet.
