摘要
在深入研究基于二维传感器测倾角技术的基础上,分析了利用三维传感器测姿态角的原理方法,该方法可减小因二维传感器单轴或双轴输出带来的随机性系统误差,可实现同时对倾角与滚转角的测量;在后续的数据处理方法选择上,运用了基于加权移动平均平滑滤波的修正方法,并在仿真与实验中得到了验证,提高了数据的精度,取得了较好的效果,为特殊行业的测姿提供了理论支持。
On the basis of an indepth study of inclination angle measurement techniques with twodimensional sen sor, a principle method using threedimensional sensor to measure attitude angle is analyzed. The method can reduce random systematic errors caused by uniaxial or biaxial output of the twodimensional sensor, and can measure both inclination angle and roll angle simultaneously. As to the selection of subsequent data processing methods, a revised method based on weighted moving average smoothing filtering is used. Simulation and experiment results verify the validity of the method. What＇s more, the method improves the data accuracy, achieves preferable results, and pro vides a theoretical support for the attitude determination in particular industries as well.
