摘要
近年来,随着物联网技术的发展与智慧城市概念的提出,基于位置的服务快速发展,尤其是由基于卫星信号的全球定位系统(GPS)提供定位的室外位置服务已经深入日常生活的方方面面。然而,GPS在室内定位中受复杂的室内环境影响有着较大的误差,为了提高室内位置服务的定位精度,多种室内定位技术被相继提出。其中,利用现有设备(如Wi-Fi、低能耗蓝牙(BLE)和智能手机等)提供的多种信号信息,通过数据分析、机器学习等技术来提供室内定位服务,具有成本低、部署使用便捷等优点,受到了越来越多的关注。文中梳理了近年来低成本室内定位技术的相关成果,介绍了其基本原理、实现方法以及能达到的定位精度,分析了各种技术的优缺点,并对未来发展趋势进行了展望。
Recently, with the development of Internet of things technology and the proposal of smart city concept, location-based service is developing rapidly, especially, the outdoor location services provided by global positioning system(GPS) based on satellite signals have penetrated into every aspect of out daily life.However, GPS is not applicable for indoor space due to the low localization accuracy, affected by the complex indoor environment.In order to improve the localization accuracy, indoor localization techniques are proposed.The techniques which utilize the existing devices such as Wi-Fi, low energy Bluetooth(BLE) are attracting more and more attention due to their advantages of low cost and easy deployment.This paper surveys the recent research work of low-cost indoor localization techniques with the basic motivations, implementations and their localization performance.Finally, the future development trend is prospected.
