摘　　要：针对个人足部导航MEMS器件误差较大,直接影响个人导航精度的问题,论文采用了一种十二位置标定法。首先建立陀螺仪和加速度计的输入输出误差模型,然后给出十二位置标定的位置编排,最后通过三轴转台实验,得出标定结果。结果表明,补偿后的MEMS器件误差有所减小,为提高个人鞋式导航系统的精度打下了基础。On account of the problem that the error of personal shoes navigation using MEMS devices is biggish and directly affects the accuracy of personal navigation , this paper uses a twelve position calibration method. First the input and output error model of gyroscopes and accelerometers is established. Then the paper gives twelve positions calibration location layout. At last, through the experiment of the three-axis turntable the calibration results are obtained. The results show that the error of MEMS devices is reduced after compensation and it could improve the accuracy of personal shoes navigation system.
