摘要
为解决室内定位系统前期信息采集工作量大,成本高的问题,将惯性导航技术应用到室内定位中来。通过对智能手机中的加速度计和电子罗盘传感器的研究,设计了一个手机应用。该系统建立在Android系统上,对手机传感器产生的信号进行计算,实现定位功能。并对误差产生原因进行分析,并通过粒子滤波技术提高其定位精度,在短距离内定位精度控制在在3～5m。为惯性导航在手机定位中的普及和应用提供了理论基础。
After the analysis of existing localization system,based on Micro-Electro-Mechanical System （MEMS） is established in this paper.The whole system is based on Android system,and realized positioning function by sensor signal calculation.The localization results is analyzed and calculated.The reasons that affect system accuracy and efficiency have also been analyzed with the suggestions for the system performance improvement.The research results show that the indoor localization system can locate in an ideal environment and the average localization accuracy is 3-5m.
