Positioning method and positioning system of location fingerprints

The invention discloses a positioning method and a positioning system of location fingerprints. The positioning method of location fingerprints comprises the following steps of: (1) dividing a first region, in which a positioned point is located, into a plurality of second regions, and selecting a plurality of sampling points in each second region; (2) collecting information about access point signal receiving strength of each sampling point, recording coordinate information and region attribute information of the sampling points, and inputting the collected information to a database; (3) creating a corresponding table of lists about region attributes and access point medium access control addresses; (4) extracting the access point medium access control addresses of the first m sampling points with the highest access point signal receiving strength, performing retrieval in the corresponding table, and matching n regions having the highest coincidence degree of the access point medium access control addresses with the m sampling points; and (5) extracting location fingerprint points in the n regions from the database, performing data correlation method operation with the sampling information of the positioned points, and acquiring location coordinate information of the positioned points.
