摘要

对基于参考标签的最近邻居定位算法提出了若干改进

提出了动态k值设定的方法

参考标签可信度的概念和最近邻标签偏差校正算法

并采用了目标标签历史轨迹算法。基于多天线的时分复用搭建了室内定位系统

并且依据改进后的算法开发了相应的界面软件。实测表明改进算法的定位精度和在恶劣环境下定位结果的稳定度比原算法有了明显提高。

Abstract

Several improvements of the existing reference tag-based nearest-neighbor positioning algorithm were intro-duced

including the method of dynamic setting of k value

the concept of reference tags’ credibility and the algorithm of correction based on the positioning error of nearest tags.The algorithm based on the historical track of object tags was also adopted.The indoor positioning system was built with time-division multi-use antennas connected to its RF-ports.The visual software was also developed based on the algorithm proposed.Positioning accuracy and stability in complex environments were proved by experiments to be better than that of the existing algorithm.
