Research of location fingerprint based on three-dimensional indoor positioning system

摘要

This paper proposed a solution to the three-dimensional indoor positioning system based on location fingerprint method. Especially, it proposed an automatic offline collection method and realizes an off-line collection system, including a collection server and a mobile collection application, 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 paper improves the algorithm based on the location fingerprint, which improves the positioning accuracy and optimizes the positioning performance.
