UKF Fusion Estimation for Indoor RFID Tracking
Xue Bo Jin · Applied Mechanics and Materials · 2013
Radio frequency identification (RFID) can effectively get the accurate location information for indoor tracking system. The readers cant be placed at any position in the practical system. the reader would be more intensive at some places, where will obtain measurements from several readers, while the reader will be placed less at others place, where less or no measurements may be get when the target gets in this area. Therefore the target trajectory should be estimated by fusion filtering methods with variable sensors. The experiments show that the fusion UKF with variable sensors can overcome RFID nonlinear is smooth without abrupt change, even when the number of sensors has undergone great changes.
