Abstract

Embodiments of the present invention provide a positioning method and device based on a neural network-based fingerprint space interpolation method, which determines an extended AP of an unknown fingerprint through an original AP of a known fingerprint. By utilizing the characteristics of AP fingerprint information, the obtained extended AP fingerprint is more accurate. In addition, the expanded fingerprint library is used to obtain the position of the point to be located. On the basis of the original AP with known fingerprints in the original fingerprint database, more extended AP fingerprints are inserted to automatically expand the original fingerprint database, which can effectively reduce the collection workload of the expanded fingerprint database and can use limited fingerprint data. More expansions are obtained, and positioning results with higher positioning accuracy are obtained.

Description

technical field [0001] The invention relates to the field of positioning technology, in particular to a positioning method and device based on a neural network-based fingerprint space interpolation method. Background technique [0002] When the location fingerprint technology is used for positioning, a wireless local area network (Wireless Local Area Networks, WLAN for short) fingerprint library will be used. The establishment process of the fingerprint library is to sample the signal value in the location location in advance before positioning to establish the fingerprint library. During the establishment of the fingerprint database, the location fingerprint database is established by using the mapping relationship between the Received Signal Strength (RSS) value and the space. [0003] In order to establish a more accurate fingerprint library, it is often necessary to repeat sampling in different time periods many times. The more spatial points in the fingerprint library,...
