摘要
由于室内环境下消费级、企业级应用的需求推动,基于室内位置的服务在信息系统中的重要性日渐凸显。室内定位技术作为基于位置服务的核心,存在众多的可选方案。从室内定位算法、测量技术和融合定位技术三个方面对各种室内定位技术进行梳理,并对距离测量、指纹定位、SLAM技术、惯性导航等多种适用于不同场景定位技术的基本原理进行综述;从定位技术特点、定位需求的角度对各种定位技术进行了对比分析;探讨了室内定位中的识别与分辨能力、定位系统容量、快速的定位系统部署能力等基于位置服务的问题,继而讨论了目前室内定位技术推向应用实践所面临的挑战。
Due to the demands for consumer and enterprise applications in indoor environments,indoor locationbased service has played an increasing critical role on the basic service of information system.Many solutions have been proposed in the area of indoor positioning technology as the core of location based services.This article surveys the indoor positioning systems from three aspects,i.e.,measurement technology,localization algorithm,and fusion positioning technology.This paper summarize the principle of the positioning technology from distance,fingerprinting,SLAM technology,inertial navigation and so on.Moreover,this paper make a comparative analysis of various positioning technologies from the perspective of the characteristics and needs of positioning technology.This paper discusses the problems of location-based services in indoor positioning,such as recognition and discrimination ability,positioning capacity,and rapid deployment capability.Finally,this paper discuss the challenges faced by the applications of indoor positioning technology.
