Fingerprint locating method and server

Abstract

The invention discloses a fingerprint locating method and server. An establishing stage and an updating stage of a fingerprint database are carried out simultaneously, and the problem that a traditional fingerprint locating method firstly and manually establishes a fingerprint database to consume a lot of labor and materials and be small in coverage density and unchanged in fingerprint database is solved. In actual engineering application, the fingerprint database is automatically established and continuously updated automatically to keep pace with the environmental change, so that resources are saved, and the locating accuracy is improved. The fingerprint database is in a steady state finally and can further slowly adapt to the environmental change. In statistical time, the locating accuracy of the fingerprint locating method and server is stable, the fingerprint locating method and server is better than a traditional locating algorithm, and the divergence of the locating accuracy of the traditional locating algorithm on the same point in different moments is reduced.

Description

technical field [0001] The invention relates to the technical field of mobile communication positioning, in particular to a fingerprint positioning method and a server. Background technique [0002] With the development of communication technology, as a part of mobile communication and personal communication service, location service becomes more and more important. [0003] Fingerprint positioning technology is a commonly used technology in indoor location services. Traditional fingerprint positioning technology needs to establish a database in the early stage, that is, artificially measure each positioning point to establish a database. In the later stage, the online data is compared with the data in the database to find matching data to achieve positioning. [0004] The disadvantage of the above-mentioned traditional method is that it consumes a lot of manpower, and the coverage density cannot be too high. In addition, the artificially established database is fixed, but...

Problems solved by technology

[0004] The disadvantage of the above traditional method is that it consumes a lot of manpower, and the coverage density cannot be too large

In addition, the artificially established database is fixed, but the flow of personnel and the movement of materials in the positioning scene will change the actual data, which will cause the data in the database to gradually deviate from the actual data, making the positioning error continue to increase
