在現今的生活中,隨著智慧型手機和行動網路的普及化,人們開始追求將手機上快捷便利的服務模式應用到其他領域,也因此依賴由定位與導航所衍伸的行動定位服務(Location-Based Service,LBS)需求逐漸提升。然而最普及的全球定位系統(Global Positioning System,GPS)的訊號會被建築物的許多因素所阻礙,進而發展出室內定位的需求。因此智慧型手機透過許多的應用程序利用不同的技術以及感測輸入來進行室內定位。大多數的室內定位(Indoor Positioning)系統都依據從室內無線發射裝置所接收到的接收訊號強度(Received Signal Strength Indicator,RSSI)來當作定位的參考。但是在現實情況下,室內定位系統的精準度容易因訊號干擾而受到影響,所以藉由整合室內定位的各式方案,以促進室內定位的精準,使其更容易得到對應的室內位置資訊。
在此論文中,我們提出並比較了使用行人航位推算(Pedestrian Dead Reckoning,PDR)技術,接收訊號強度指紋(RSSI Fingerprint),以及綜合機器學習演算法(Ensemble Machine Learning),以及組合式系統,以便可以找到可以輕鬆便宜應用在現今商品現貨設備上的方案,而以上方案的室內定位方式是藉由訊號紋路特徵比對,以及智慧型手機(Smartphone)的感測器輔助,讓其使用者可以得到所在的室內位置。我們所設計的方案在實驗結果中,顯示此些方案是非常有希望改善室內定位的精準度,縮小其定位的誤差距離,並且容易在現有的裝置上實現。
Nowadays, there is an increasing demand for indoor localization and navigation services with readily available Commercial off-the-shelf (COTS) devices, such as smartphones or wearable devices. Many applications on smartphones exploit different techniques and input for positioning. Most of these systems rely on Received Signal Strengths (RSSs) from indoor wireless emitting devices. However, the accuracy of indoor position systems is easily affected by signal interference in realistic situations.
In this paper, we propose and compare several indoor localization and navigation systems using Pedestrian Dead Reckoning (PDR), fingerprinting, ensemble machine learning, and hybrid systems, in order to find schemes that can be easily and cheaply applied to COTS devices.
