人手三维运动检测系统

3-D Motion Detection System of Human Hand

提出了一种基于普通摄像机的人手三维运动检测系统 ,它包括两部普通摄像机、标定架和标志点识别子系统等。该系统采用直接线性变换 (DL T)算法 ,可以对人手运动进行可靠的三维检测。本文叙述了该系统的工作原理以及测试实验 ,测试结果显示了该系统良好的三维运动检测性能。本系统的研制为更好地进行人体运动质量的分析和评价、更有效地揭示人体运动规律提供了经济方便的实验手段和研究途径。

This paper presents a 3 D motion detection system of human hand, which is based on ordinary video cameras. It includes two pickup cameras, calibration frame and landmark identification system. The DLT algorithm is used to reconstruct the 3 D motion trajectory of human hand. The paper also presents the principle of the system and some detection experiments, and the results showed the good performance of the system. It offers a useful tool for the human hand motion quality analysis and evaluation.
