本文描述了一种自给式、可穿戴的全身运动捕获系统的可行性研究，该系统基于飞行时间测量，提供身体上各点之间的绝对距离。我们开发该系统的目的是让电子纺织服装只使用身体佩戴的传感器来感知自己的形状，从而使其能够动态调整其传感和处理元素，以适应用户的当前姿势。此外，一件可以感知自己形状的衣服将使一个不受束缚的、自给自足的运动捕捉系统成为可能。我们通过由多个用户执行各种活动的运动数据驱动的仿真来探索系统的潜在精度，这些活动包括传感器在躯干上的数量和位置、身体对信号传输的阴影以及传感器的方向性。我们的结论是，该系统是可行的，尽管其精度至少比最先进的实验室系统低一个数量级，其精度将在很大程度上取决于传感器的传输特性。
This paper describes a feasibility study for a self-contained, wearable full-body motion capture system based on time-of-flight measurements that provide absolute distances between points on the body. Our motivation for the system is to allow an e-textile garment to sense its own shape using only body-worn sensors, thereby enabling it to dynamically adapt its sensing and processing elements to the user's current pose. Furthermore, a garment that can sense its own shape would enable an untethered and self-contained motion capture system. We explore the potential accuracy of the system via simulation driven by motion data from several users performing various activities, including effects such as the number and placement of sensors on the torso, shadowing of signal transmission by the body, and sensor directionality. We conclude that the system is feasible, albeit with an accuracy that is at least an order of magnitude less than state-of-the-art laboratory systems, and that its accuracy will depend heavily upon the transmission properties of the sensors.
