室内定位方法综述

近年来,随着情景感知、环境智能等应用需求不断增加,对用户位置信息精度的要求也在不断提高。因室内环境复杂、缺乏统一的基础性架构等因素,室内定位方法逐渐成为用户定位领域的研究热点。考虑到室内定位方法的基础架构、位置精度、方法普适性等因素,将现有的室内定位方法分成3大类:基于特定设备的定位方法、基于WIFI的定位方法和基于移动传感器的定位方法。针对具体定位算法及不同算法的性能、特点和优劣等进行探讨和分析,最后总结当前室内定位方法领域的研究现状,并简要介绍该领域未来的研究方向及发展趋势。

Survey on Indoor Localization

In recent years,with an increasing demand of context-aware applications and ambient intelligence applications,the accuracy requirements of user location information are rising.Due to the fact of complex indoor environment and the loss of unified infrastructure,indoor positioning technology has gradually become the focus field of user localization.Taking into account the infrastructure of indoor positioning technology,location accuracy,generality and other factors,the existing methods were divided into three categories:specific device-based localization,WIFI-based localization and mobile sensor-based localization.We discussed and analyzed specific localization technology and different me-thods,such as performance,features,advantages and disadvantages,etc.Finally,we summarized the current state of indoor localization technology field,and briefly described the direction of future research and development trends in the field.
