Paper Summary

Paper Name InLoc: An End-to-End Robust Indoor Localization and Routing Solution using Mobile Phones and BLE Beacons
Published in 2016 IEEE International Conference on Indoor Positioning and Indoor Navigation (IPIN)
Authors Vivek Chandel; Nasimuddin Ahmed; Shalini Arora; Avik Ghose
Paper Overview ‘InLoc’, an accurate and a robust positioning and tracking system using commercial mobile devices.

‘InLoc’ integrates feature of route finding for the user from a source to the desired destination.

Novel contributions

  • Raster Floor Map convert to Vector Floor Map
  • RSSI to distance using Machine Learning
  • Location fusion of inertial and BLE beacon
Experiment results

Methodology

  • Map processing : Use standard edge detection techniques based on adaptive brightness cutoff
  • BLE Beacon Location Estimation : RSSI convert to Distance using machine learning
  • Inertial Tracking : For a real-time location tracking, we use IMU sensors embedded in the phone to send the per- step updates to the location server. The location server runs an instance of a particle filter (PF).
  • Routing : The grid representation to derive the graph G = (E, V ), This definition of G can be used readily with algorithms like Dijkstra’s algorithm
  • Location fusion : We calculate an independent location from the beacons, and fuse it with the latest inertial module’s location
