移动机器人室内无源RFID定位方法及实现
Localization method and implementation for indoor robot based on RFID.
摘要
Abstract
In order to improve the positioning accuracy of indoor mobile-robot, a new positioning method has been designed based on passive RFID. In this paper, RFID beacon is arranged as cellular model for improving the card reader efficiency;RSSI positioning method correction model is put forward with engineering practice;for the optimal value problem in posi-tioning process with multiple beacons, Differential Evolution algorithm is introduced. Final, physical verification is designed within the scope of(4×4)m2. The experimental result shows that, the method has higher positioning accuracy than MLE, absolute error is less than 7%of the RFID beacon interval;it can obtain optimal value in less iteration steps than standard genetic algorithm, 37%less computation time has saved.关键词
