A radio frequency identification target positioning method based on an unmanned aerial vehicle comprises the steps: enabling an unmanned aerial vehicle to carry a relay module to enter an environment,and carrying out the large-range label identification and information collection through the function that the relay module carries out secondary forwarding on signals; by utilizing the influence ofthe unmanned aerial vehicle body on the label signal strength, collecting the change condition of the signal strength, obtaining a label group which is mainly influenced and changed according to the weighted average value, and determining the position of the target label. According to the target positioning method, the maneuvering characteristics and the automatic cruise function of the unmanned aerial vehicle are utilized, and the relay module is carried, so information capture and target positioning can be completed under the conditions of large scale and complex environment, the high efficiency of data capture and the accuracy of target positioning are ensured, the error amount is reduced, the workload is greatly reduced, and the working process is simplified.
一种基于无人机的射频识别目标定位方法,无人机搭载中继模块进入环境中,利用中继模块对信号二次转发的功能来进行大范围的标签识别以及信息的收集;利用无人机机身对标签信号强度的影响,收集信号强度的变化情况,根据加权平均值得出受主要影响变化的标签组,确定目标标签的位置。本目标定位方法,利用无人机的机动性能、自动巡航功能和搭载中继模块,能够在规模较大、环境复杂的条件下完成信息捕获和目标定位,并且保证了数据捕获的高效性及目标定位的准确性,降低错误量,极大减轻了工作量,简化了工作流程。
