wifilocalizationdemo's Introduction

WiFiLocalizationDemo

###简介

一个使用wifi进行室内定位的Android应用程序。手机扫描附近WiFi热点,将信号强度与数据库进行对比,实现knn算法,确定当前位置并显示。

###原理介绍

程序内部记录了指纹库,即位置坐标与信号特征的对应关系,通过KNN算法即可根据当前的信号特征预测实际位置。

###其他

本项目目前只能在天津大学26楼使用,将不定期更新,逐渐增加以下功能:

  • 地图导入与指纹库的制作,可以考虑在线上传和下载数据
  • 使用传感器增加惯性导航功能,混合定位可以达到更流畅、更高精度的效果。
