Zusammenfassung:Wireless position tracking systems can be used in applications, such as mobiles, robot tracking systems, and Internet location-based service (LBS) applications. The GPS system is the best-known position tracking system for use in outdoor locations through satellite tracking systems. Cost-effective radio frequency identification (RFID) tracking methods for indoor systems have also been developed. However, most of these systems use active RFID tags that use expendable batteries. We develop a low-cost indoor position tracking system that uses passive RFID. The proposed indoor tracking system, using a precise tracking algorithm, is applied to various locations. The system is tested by validating the signal-to-noise level caused by errors. B-spline surfaces generated by an approximation formula are used as baseline data. This proposed system can also be applied to mobile robot systems, automated guided vehicles (AGVs), and phone LBSs.
