Construction Method of Location Fingerprint Database Based on Gaussian Process Regression Modeling

Abstract

In the terms of indoor positioning, the location of the fingerprint technology that based on receiving wireless LAN WIFI signal strength (RSS)

Position of Fingerprint Location based on Improved Universal Kriging Interpolation Method

“…Thus, the drift function () Ml of a certain point is considered as a polynomial combination based on the position information of the point, and the deterministic partial drift function can be expressed as a polynomial. They are calculated in Equations (4) and (5)…”

“…The position fingerprint method is a scene analysis method. Because the algorithm can be pure software and can have a higher accuracy, this method has been widely used [4][5]. It is divided into two stages: the offline stage, which involves the wireless signal strength as the scene characteristic and constitutes the location of the finger-print database [6], and the online stage, which involves the use of matching algorithm real-time access to location information [7].…”
