ZigBee-based intelligent indoor positioning system soft computing
Nowadays positioning system is no longer only for military purpose, while it has been widely applied to various livelihood purposes such as biological information, emergency rescue, public facilities and individual safety. While the most frequently used to identify the coordinates of users is global positioning system (GPS), however, it tends to be interfered by indoor buildings such that it ca...
متن کاملAccurate Intelligent Map Matching Algorithms for Vehicle Positioning System
The purpose of a navigation system installed on a car is to help drivers in order to select an optimal path to reach the destination. In most of these systems, Global Positioning System (GPS) are used to determine vehicle position. There are number of error sources that undermine the quality of GPS measurements for car navigation systems. For this reason, technique like Map Matching (MM) is req...

متن کاملInfrared Sensor System for Mobile-Robot Positioning in Intelligent Spaces
The aim of this work was to position a Mobile Robot in an Intelligent Space, and this paper presents a sensorial system for measuring differential phase-shifts in a sinusoidally modulated infrared signal transmitted from the robot. Differential distances were obtained from these phase-shifts, and the position of the robot was estimated by hyperbolic trilateration. Due to the extremely severe tr...
متن کاملAn Image-based Positioning System
In this paper we address the problem of building an efficient database management system that allows querying for similar images. This system, which supports imagebased queries on a database of photographs taken around the campus, helps the user to identify his/her location on a campus map. We have implemented and analyzed two classes of image retrieval techniques. In the first technique, the d...
