Research on location fingerprint towards three-dimensional indoor positioning system

Abstract

This paper proposed a solution to three-dimensional indoor positioning system based on location fingerprint method. Especially, this paper proposed a automatic offline collection method and realizes a off-line collection system, including a collection server and a mobile collection applications, which can be used to collection the information of location fingerprint conveniently, and also improve the efficiency of the off line collection. Moreover, this paper studied the three-dimensional positioning system based on the location fingerprint method, which can obtain the indoor location information with a relative high accuracy. In addition, the authors improve the algorithm based on the location fingerprint, which improves the positioning accuracy and optimizes the positioning performance.
