摘要

运动捕捉系统是一项具有广泛应用前景的关键技术。目前，基于组件间的运动捕捉系统已成为一个新的研究热点。本文提出了一种基于9自由度微惯性传感器MPU9250和STM32F103C8T6单片机的低成本可穿戴无线惯性测量单元的设计方案。采用超低功耗(ULP) 2Mbps射频收发芯片NRF24L01作为射频收发器，工作在2.4GHz ISM(工业、科学和医疗)频段，RX/TX峰值电流低于14mA。最后，利用Unity3D 5.6在PC上编写了传感器实时姿态显示程序，实验表明该程序在静态和动态状态下都具有良好的性能。

The Design of Wearable Wireless Inertial Measurement Unit for Body motion Capture System

Motion capture system serves as a critical technology in a wide range of applications. Nowadays, motion capture system based on inter components has become a new research hotspot. This paper provides a new design of low cost wearable wireless inertia measurement unit based on a 9-DOF micro inertia sensor MPU9250 and STM32F103C8T6 MCU. Furthermore, an ultra-low power (ULP) 2Mbps RF transceiver IC NRF24L01 was used as RF transceiver, which operates in 2.4GHz ISM (Industrial, Scientific and Medical) band, with peak RX/TX currents lower than 14mA. Finally, a program was built by Unity3D 5.6 on PC to display sensors real-time attitude and the experiment shows it has good performance in static and dynamic state.
