摘要： Indoor positioning systems based on wireless local area networks are growing rapidly in importance and gaining commercial interest. Pedestrian dead reckoning (PDR) systems, which rely on inertial sensors, such as accelerometers, gyroscopes, or even magnetometers to estimate users' movement, have also been widely adopted for real-time indoor pedestrian location tracking. Since both kinds of systems have their own advantages and disadvantages, a maximum likelihood-based fusion algorithm that integrates a typical Wi-Fi indoor positioning system with a PDR system is proposed in this paper. The strength of the PDR system should eliminate the weakness of the Wi-Fi positioning system and vice versa. The intelligent fusion algorithm can retrieve the initial user location and moving direction information without requiring any user intervention. Experimental results show that the proposed positioning system has better positioning accuracy than the PDR system or Wi-Fi positioning system alone. 其他題名： JSEN 出版者： IEEE 出版日期： 2014-11 出處： IEEE sensors journal, 2014-11, Vol.14 (11), p.4034-4042 資源來源： IEEE Xplore Digital Library (LUT) 識別號： ISSN: 1530-437X 識別號： EISSN: 1558-1748 識別號： DOI: 10.1109/JSEN.2014.2330573 識別號： CODEN: ISJEAZ
