基于ARM-Linux的微惯性单元数据采集与处理

MEMS IMU data acquisition and processing based on ARM-Linux

在Linux下通过串口编程对MEMS IMU数据采集和解算,实现了其高速实时采集。其中,设计的ⅡR低通滤波器有效消除了信号中的噪声成分,并通过Qt编程设计了应用程序窗口将MEMS IMU的输出数据动态显示在ARM开发板上。该设计在小体积、低功耗、低成本的惯性测量中具有重要的工程应用意义,可广泛应用于动态测量、动态控制、辅助导航等领域。

In the way of serial port programming the real-time data of MEMS IMU was speedly acquired and decoded. Analysing the data,the paper designed an IIR lowpass filter to reduce the influence and interference of noise. And an output window was designed to display the data that got on the screen of the ARM development board.The design ,with its valuable characters of small size,low power consumption and low cost,can be widely applicated in many areas such as dynamic measurement , dynamic controlling and auxiliary navigation.
