用单个摄像机实现实时越位判定，降低成本。
Real Time Offside Detection using a Single Camera in Soccer
- 仅用一个广播摄像头实现越位检测
- 可替代传统多相机系统，节省成本
- 适合预算有限的赛事或训练场景
过去十年间，足球技术发展迅速，改变了比赛多个方面。与简单二元规则不同，许多足球规则（如越位规则）依赖主观判断而非明确的真/假标准。场上裁判拥有最终裁决权。近年来，视频助理裁判（VAR）系统成为重大突破，通过球场内20-30个摄像头网络减少人为错误。通常，VAR系统覆盖10-30个摄像头，确保高决策准确率，但成本高昂。本报告提出一种创新方法：使用单个摄像头（如转播摄像头）实现越位检测，以降低复杂技术部署带来的费用。
原文摘要 · Abstract (English)
Technological advancements in soccer have surged over the past decade, transforming aspects of the sport. Unlike binary rules, many soccer regulations, such as the "Offside Rule," rely on subjective interpretation rather than straightforward True or False criteria. The on-field referee holds ultimate authority in adjudicating these nuanced decisions. A significant breakthrough in soccer officiating is the Video Assistant Referee (VAR) system, leveraging a network of 20-30 cameras within stadiums to minimize human errors. VAR's operational scope typically encompasses 10-30 cameras, ensuring high decision accuracy but at a substantial cost. This report proposes an innovative approach to offside detection using a single camera, such as the broadcasting camera, to mitigate expenses associated with sophisticated technological setups.
