【摘要】 随着人们对基于位置服务需求的增加,使用GPS、RFID等技术的定位系统已不能满足一些室内位置服务的需求。由于WiFi技术不断升级和内置WiFi模块终端设备的普及,WiFi室内定位系统成为当前研究的热点。笔者主要介绍了利用手机的WiFi模块和Android平台,测量待定位区域并建立信号位置指纹数据库,采用相关算法匹配待定位终端的特征信号与指纹库,实现终端的室内定位。更多还原

【Abstract】 With the increasing demand for location-based services, positioning systems using GPS, RFID and other technologies can not meet the needs of some indoor location services. With the continuous upgrading of WiFi technology and the popularity of built-in WiFi module terminal equipment, WiFi indoor positioning system has become a hot research topic. This paper mainly introduces the use of WiFi module and Android platform of mobile phone to measure the location area and establish the fingerprint database of signal position, and use related algorithms to match the characteristic signals and fingerprint database of the terminal to be located, so as to realize the indoor location of the terminal.更多还原
