Abstract

The embodiment of the invention provides a positioning method and device for a fingerprint spatial interpolation method based on a neural network, and the method comprises the steps: determining an extended AP of an unknown fingerprint through an original AP of a known fingerprint; and utilizing the characteristics of the AP fingerprint information, so that the obtained extended AP fingerprint ismore accurate. In addition, the expanded fingerprint database is used to obtain the position of the point to be positioned. On the basis of the original APs with the known fingerprints in the originalfingerprint library, more fingerprints of the extended APs are inserted to automatically extend the original fingerprint library, so that the acquisition workload of the extended fingerprint librarycan be effectively reduced, more extension can be achieved by using limited fingerprint data, and a positioning result with higher positioning precision is 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,...
