面向智能导游的室内外定位方法研究

摘要

Intelligent tourist guide is an integrated service of tourist location-based path guide and tour guide, which is closely based on GIS, mobile positioning technology, and LBS. At present, the outdoor location technologies are well developed. However, they are not available indoors. So, the integration of indoor and outdoor positioning technology and its application in the field of intelligent guide urgently are needed to be improved. This paper aims to incorporate outdoor and indoor positioning technologies into scenic tour service. Based on the investigation of various indoor and outdoor positioning technologies, the paper studies the indoor and outdoor integrated positioning method based on GPS and UWB, and proposes an indoor and outdoor combination mode based on visitor behavior and spacial status. Finally, an integrated GPS and UWB outdoor and indoor positioning platform is built by constructing positioning switching algorithm using motion detection.%智能导游是基于游客位置的路径引导、游览讲解的综合性服务，与地理信息系统（GIS）、移动定位技术、基于位置的服务（LBS）等之间有着密切的联系。目前，室外定位技术已趋于成熟，但是无法满足室内定位的要求，因而室内外一体化定位在智能导游领域的应用亟待研究。本文将室内外定位引入到景区智能导游服务中，在调研室内外定位技术的基础之上，根据景区智能导游系统中室内外定位的具体需求，研究基于全球定位系统（GPS）和超宽带技术（UWB）的室内外组合定位方法，提出基于游客行为与空间状态的室内外组合定位模式，通过探测游客的运动状态实现定位切换算法，构建基于GPS与UWB的室内外组合定位平台。
