摘要
为解决无法在室内使用GPS的问题,设计并实现了基于常用手持设备(如手机、平板电脑)的室内定位系统。系统融合了传统的惯性定位方法和基于WiFi信号强度定位方法,易于搭建,仅需一个包含惯性传感器、电子罗盘、WiFi扫描的手持设备。提出了惯性定位中的路径匹配算法和WiFi信号定位方法中的位置估计算法。经实际测试,系统定位精度小于4m。
Designing an indoor location system based on handheld device to resolve the matter that cannot use GPS for indoor location. This system has two feature, the first is combining the inertial positioning and WiFi positioning; the second is the system is very simple, just need a handheld device that include WiFi, compass, inertial sensor. Present a path matching algorithm used in inertial positioning and site estimated algorithm used in WiFi positioning. It has been found that the precision of system is less than 4 m.
