Design and Implementation of a RFID Based Positioning Method for Indoor Vehicle Monitoring System
一种基于RFID的室内车载监控系统定位方法的设计与实现

Indoor positioning is one of the key techniques for supporting home environment inspection over smart home.We presented a RFID based indoor positioning method and implemented a smart vehicle system with it to support spontaneous home environment monitoring.In the proposed approach,we first built up an indoor coordinate system using a set of deployed RFID tags,and then dynamically detected the moving direction of vehicle system with an electronic compass.We further presented a vector projection algorithm to compute the center location of the vehicle system,thus improving the precision of indoor positioning.The real performance of the implemented vehicle system shows that our proposed RFID based indoor positioning method can work effectively and efficiently.
