摘要/Abstract

摘要： 研究并实现一种基于Android手机终端固有IMU和GPS模块的无缝组合定位方法,给出了系统设计方案及实验结果。在GPS信号缺失时利用手机终端固有的IMU惯性传感器采集行人运动信息完成步态检测、航向解算和航迹推算,实现GPS信号缺失环境下的无缝定位。基于Android系统和百度地图的开放平台在手机终端完成算法实现和人机交互。测试结果表明,GPS信号缺失环境下的单一IMU定位方案得到的系统定位相对误差可控制在5 m范围内,可满足一般室内环境下的导航定位要求。

Abstract: The method of seamless combination of IMU and GPS module based on Android mobile terminal is researched and implemented, and the design scheme and experimental results are given. When the GPS signal is missing, the gait detection, heading calculation and track estimation can be carried out by using the IMU inertial sensor which is inherent in the mobile terminal to complete the seamless positioning. Based on the Android system and the open platform of Baidu map, the algorithm implementation and human-computer interaction can be completed in the mobile terminal. The test results show that the relative error of the system location can be controlled within 5 meters by the single IMU positioning scheme in the absence of GPS signal, which can meet the navigation and positioning requirements in the general indoor environment.

Key words: seamless positioning, inertial measurement unit, satellite navigation system, Android platform
