摘　　要：针对现有卫星定位方案存在室内环境中无线屏蔽效应的问题,设计一种基于Android移动终端的室内惯性定位方案:利用Android智能终端内置惯性器件采集行人运动数据,通过分析加速度计、陀螺仪、电子罗盘数据检测行人运动步频、步长和航向;根据行人航迹推算原理,基于JAVA语言在Android终端实现室内定位软件的设计。室内环境下的行人测试结果表明,行走距离250m引起的最大定位误差能够优于6.2m。Aiming at the problem that there exist radio signal shielding effect in indoor environment for current satellite positioning methods,the paper proposed an indoor inertial positioning scheme based on Android mobile device:the built-in inertial sensors of Android device were used to collect pedestrian data,and stride frequency,stride length and heading were detected by analyzing the data of accelerometer,gyroscope and compass,then based on the principle of pedestrians dead reckoning,the indoor positioning software was realized with JAVA on Android terminal finally.Experimental result showed that by the proposed method,the maximum positioning error could be less than 6.2 m with 250 m walking distance.
