A Wifi Location Method Which Supports the Combination of Position and Location Fingerprint

Abstract

Based on the analysis of position fingerprint recognition algorithm, this paper studies the application of the flight location estimation method to the indoor positioning using mobile phone sensor. In order to improve the positioning accuracy and to solve the problem of the problem of the WiFi signal instability, the mobile sensor is combined with the position fingerprint algorithm of support vector machine, and a new method is proposed to support the position estimation method and the location fingerprint combination. The experimental results show that the method has higher positioning accuracy and reliability, and has a certain application value.
