摘要
介绍了姿态测量的原理,设计了一种基于多MEMS的无线姿态测量系统。重点介绍了用Kalman滤波器对数据的处理过程,即利用陀螺测量值更新上一步的结果,用加速度计和地磁传感器的测量值作为观测量,修正由陀螺得到的结果。完成了硬件电路的设计和算法的编程实现。该系统具有体积小、无线传输、精度较高等特点,可用于各种载体的姿态测量与显示。
This paper designed the principle of attitude measurement and a wireless attitude measurement system based on multi-MEMS.It mainly focused on the data processing with extended Kalman filter.This system used the data measured by gyroscope to renew the results of the previous step and used the data measured by accelerator and geomagnetic sensor as measured values to correct the results.The circuit was designed and the algorithm was realized.The system with high accuracy was wireless,small in size and it can be used in different situations.
