摘要
基于位置的服务对用户位置精度要求越来越高,现有室外定位技术已无法满足要求,因此室内定位研究具有重要应用价值。分析了室内定位特殊的环境因素,阐述了室内定位的基本原理、实现步骤与方法,重点分析了目前广泛使用的指纹定位技术及相关改进方法,总结了室内定位研究趋势。
The continuous development of location based service(LBS) puts forward higher requirements for the accuracy of users' position. The existed outdoor positioning technology has been unable to meet the demands of positioning accuracy, so the research of indoor positioning shows important application value and significance. This paper concentrated on inducing the general methods and procedures of indoor positioning to provide the study methods to beginners in the field. Firstly, this paper analyzed the environmental factors that affect indoor positioning;secondly, it expounded the technologies, implementation methods and algorithms of indoor positioning;thirdly,it focused on fingerprint location technology as well as its improvements. Finally, this paper summarized the research trends of indoor positioning.
