钢琴家的手指动作包含有关音符准备、重音信息以及个人标识符的信息。然而，目前还没有一种详细的手指跟踪系统可以在生态上使用：在原声钢琴上，同时对演奏产生可接受的低干扰。描述了一种光学运动捕捉系统，该系统使用单目摄像机设置来跟踪直接放置在钢琴家手指上的被动UV油漆标记。对跟踪精度和三维估计算法进行了评估。这种低成本，高效的系统最大限度地利用性能分析实验，最重要的是不局限于实验室环境。
Pianist finger movement contains information about note preparation, accent information as well as personal identifiers. However, no system for detailed finger tracking presently exists that can also be used ecologically: at an acoustic piano whilst also incurring acceptably low disruption to the performance. An optical motion capture system is described using a monocular camera setup to track passive UV paint markers placed directly onto pianists' fingers. Tracking accuracy and 3D estimation algorithms are evaluated. This low-cost, efficient system maximizes its uses in performance analysis experiments which are most importantly not confined to laboratory environments.
