研制了一种基于无线LC谐振式磁标记器的精密位置检测系统。该标记器由电感器和电容器组成，没有电池或电线，通过电磁感应无线驱动。在拾取线圈阵列的150 mm范围内，位置精度小于1 mm。通过优化设计，提高了系统的定位精度。该系统不受地球磁场的影响，可在无磁屏蔽的情况下进行高精度的运动捕捉。此外，它具有捕获多点运动的潜力，因为它允许标记具有单独的频带。
A precision position-detecting system using a wireless LC resonant magnetic marker was developed. The marker consists of an inductor and a capacitor without battery or electric wires, driven wirelessly by electromagnetic induction. The positional accuracy is less than 1 mm within 150 mm of the pickup coil array. The optimal design made it possible to improve the positional accuracy of the system. The system can be used for highly accurate motion-capturing without magnetic shielding because it is free from the earth’s field. In addition, it has the potential to capture multi-point motion because it allows the markers to have individual frequency bands.
