摘要 为了提高室内定位系统的性能,提出了一种三维空间内利用RFID技术定位目标物体的算法。算法通过接收信号强度获得天线和目标标签之间的距离,然后采用梯度下降法计算得到目标电子标签的位置。仓库定位网络实验结果显示,所建立的算法可以逐步逼近目标标签的真实位置,有效提高了三维空间内目标的定位精度,在仓库管理等室内定位系统中具有较强的实用性。 To improve the performance of indoor positioning system, this paper proposed a three-dimensional positioning algorithm. It aquired the distance between RFID antenna and target tag by RSSI, then acquired the location of the target tag based on the gradient decent method. Experiment results of a warehouse positioning network show that the proposed algorithm can gradually approach the actual location of the target tag and improve the three-dimensional positioning effectively, so it has strong practicability in warehouse management system.
