用单摄像头实现足球实时厘米级3D轨迹追踪
Real-time Localization of a Soccer Ball from a Single Camera
- 设计多模式状态模型加速优化，提升计算效率
- 在遮挡、模糊等复杂条件下仍保持厘米级精度
- 可在普通电脑上运行，适合直播场景应用
我们提出一种计算高效的单摄像机实时三维足球轨迹重建方法。与以往工作不同，该方法引入包含W个离散模式的多模态状态模型，在显著加速优化的同时保持厘米级精度——即使在严重遮挡、运动模糊和复杂背景情况下亦然。系统运行于标准CPU上，延迟低，适用于现场直播环境。在6K分辨率的俄罗斯超级联赛专属数据集上进行的大量评估表明，其性能可媲美多相机系统，且无需专用或昂贵基础设施。本工作为专业足球环境中可访问、高精度的3D球追踪提供了实用方案。
原文摘要 · Abstract (English)
We propose a computationally efficient method for real-time three-dimensional football trajectory reconstruction from a single broadcast camera. In contrast to previous work, our approach introduces a multi-mode state model with $W$ discrete modes to significantly accelerate optimization while preserving centimeter-level accuracy -- even in cases of severe occlusion, motion blur, and complex backgrounds. The system operates on standard CPUs and achieves low latency suitable for live broadcast settings. Extensive evaluation on a proprietary dataset of 6K-resolution Russian Premier League matches demonstrates performance comparable to multi-camera systems, without the need for specialized or costly infrastructure. This work provides a practical method for accessible and accurate 3D ball tracking in professional football environments.
