Abstract:V diplomskem delu smo poskušali izboljšati zanesljivost določanja položaja znotraj zaprtih prostorov, kjer ni mogoča uporaba sistemov satelitskega določanja položaja. Opisali smo najpogosteje uporabljane metode določanja položaja in principe delovanja na katerih temeljijo. Ugotovili smo, da so načini pridobivanja položajev, ki temeljijo na odtisu brezžičnih omrežij, podvrženi šumu, kar ima za posledico napačne, izstopajoče položaje. Predstavili smo metodo za izločanje izstopajočih položajev, ki temelji na izračunavanju razdalj do sosednjih položajev. Iz preostalih položajev nato določimo nov, zanesljivejši položaj. Za potrditev koncepta smo izdelali aplikacijo za mobilne naprave z operacijskim sistemom Android.

Title:IMPROVING RELIABILITY OF MOBILE DEVICE POSITIONING INSIDE CLOSED SPACES USING OUTLIER EXCLUSION
Abstract:In this thesis we tried to improve reliability of position fixing inside closed spaces, where use of satellite positioning systems is not possible. We described most commonly used methods and underlying principles on which they are based. We concluded that methods based on wireless fingerprinting are prone to noise, which results in anomalous positions. We proposed a method for exclusion of anomalous positions, based on calculation of distances to neighboring positions. The remaining position fixes are subsequently used to determine new, improved position fix. As a proof of concept we implemented an application for mobile devices running Android operating system.
Keywords:position fixing, outlier, mobile device, Wi-Fi, Android
