随着物联网技术的快速发展,通过传感网络实现定位的技术成为研究热点.通过部署传感网络,收集传感器的接收信号强度指示,设计对应的定位模型从而达到高效定位的功能.但在室内复杂多径环境下,接收信号强度指示的值容易受到外界因素的干扰,其定位的准确度和精确度将会因为多径干扰而大幅下降.为此,提出基于RTI的室内成像技术,建立成像模型,设计两种定位算法并完成相关实验.实验结果表明,均值法定位算法具有较高的准确性和精确性.

Location technology of sensor is an emerging research hot topic with the rapid development of Internet of things technology. Through the deployment of sensor networks,the receiver signal strength indicator is collected, and the corresponding positioning model is designed to achieve the function of high efficiency.But in the indoor com-plex multipath environment,its accuracy and precision drop significantly because of multipathinterference. There-fore,this paper presents imaging technology based radio tomographic imaging,establishsthe imaging model,designs two algorithms and completes related experiments. Experiment results show that mean-value algorithm has higher accuracy and precision.
