研制了一种基于LC谐振式磁性标记器的高精度无线运动捕捉系统。该标记器由带绕线线圈的软磁芯和不带电池或电线的片式电容器组成，由电磁感应作用无线驱动。该系统实现了在距摄像线圈阵列150 mm的范围内定位精度小于1 mm。与直流磁系统相比，该系统受地场噪声的影响不大，适用于无磁屏蔽的光隔离空间下的精密运动捕获。
Highly accurate wireless motion capture system using LC resonant magnetic marker has been developed. The marker consists of soft magnetic core with wound coil and a chip capacitor without battery or electric wires, driven wirelessly by the action of electromagnetic induction. The system realized the position accuracy is less than 1 mm within the space of 150 mm from the pickup coil array. Compared with dc magnetic system, the proposed system is applicable for precision motion-capturing under optically isolated space without magnetic shielding because the system is not influenced very much by the earth field noise.
