一种基于多终端动态协同的室内定位方法

摘要

由于Wi-Fi环境的高动态性,当标定样本类稀少或者逐渐失去其原始价值时,将严重影响定位精度;若重新标定样本,又会带来大量人力物力投入,不利于实际应用.针对这一问题,提出了一种基于多终端动态协同的室内定位方法——OC-ELM.该方法利用环境中多个终端提供的Wi-Fi信息动态协同定位,并在每轮定位结束后及时更新样本库.实验结果表明此方法不仅能实现高精度定位,更重要的是避免了重复的标定工作,提高了实际应用能力.%Due to high dynamic of Wi-Fi environment, positioning accuracy will be affected under the situation of fewer sam-ples of calibration or their original value lost. It will aggravate workload and be disadvantage of practical application if get new calibration samples. In order to solve this problem, this paper proposed a dynamic collaborative indoor locating method based on multiple terminals. The method used Wi-Fi information which provided by terminals for co-location of dynamic, and upda-ted sample after locating. Experimental results show that the method not only realize high precision positioning, but also can a-void repetitive calibration, beneficial to actual application.
