Abstract

The invention provides a novel indoor positioning method based on a fingerprint cluster. The novel indoor positioning method comprises a hierarchical indoor positioning method based on an affinity propagation cluster algorithm and a nearest neighbor algorithm which are combined together. Collected indoor fingerprint information is preclassified by effectively using the similarity of indoor fingerprints with close geographical positions, and fingerprints in a fingerprint database are classified into different subsets; furthermore, the time for positioning resolving is greatly shortened by a method for hierarchically resolving positioning results according to the fingerprint sets which are obtained by classification and have characteristics; meanwhile, the precision and the stability of an indoor positioning system are guaranteed.
