由于光学运动捕捉系统的有效捕捉区域受到红外摄像机数量、安装方式、分辨率和焦距的限制，人体某些部位（如手腕、肘部等）上的反射标记，多个实际受训者在执行协同交互操作时可能被遮蔽。针对这一问题，提出了一种基于电磁空间位置跟踪设备提供的附加特征信息的运动数据补偿方法。介绍了该方法的主要工作原理和具体实现过程，并通过实际应用验证了该方法的有效性和高效性。实验结果表明，该方法能够恢复丢失的捕获数据和手臂上相关遮挡标记的运动信息，避免了在有限的捕获范围内，多个实际受训者利用光学人体运动捕获系统进行协同交互操作过程中，相应虚拟操作者的仿真运动被打断和变形。
As the effective capture region of optical motion capture system is limited by quantity, installation mode, resolution and focus of infrared cameras, the reflective markers on certain body parts (such as wrists, elbows, etc.) of multi-actual trainees may be obscured when they perform the collaborative interactive operation. To address this issue, motion data compensation method based on the additional feature information provided by the electromagnetic spatial position tracking equipment is proposed in this paper. The main working principle and detailed realization process of the proposed method are introduced step by step, and the practical implementation is presented to illustrate its validity and efficiency. The results show that the missing capture data and motion information of relevant obscured markers on arms can be retrieved with the proposed method, which can avoid the simulation motions of corresponding virtual operators being interrupted and deformed during the collaborative interactive operation process performed by multi-actual trainees with optical human motion capture system in a limited capture range.
