Abstract

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.
