摘要
室内定位随着情景感知与位置服务兴起的一门新鲜科学。经历过数十年的研究,目前已经有大量的针对室内定位的技术方案,其中尤以指纹定位居多。室内指纹定位包含一系列的利用接收信号的强度来判定接收者位置的技术。文章重点讲述了基于位置指纹的定位技术,包括确定型指纹定位技术与概率型指纹定位技术,提炼出了利用指纹定位技术的数据模型,展示了利用数学模型来描述信号指纹库以及位置估计的方法。
The indoor localization is a new technology arisen with the development of context aware and location-based service. At present, there are numerous technical methods of indoor localization, especially fingerprint localization. The term ＂indoor fingerprint localization＂covers a series of techniques of determining receiver position by using received signal intensity. This paper describes in detail the localization techniques based on location fingerprint, including including deterministic and probabilistic fingerprint localization techniques, design the data model based on fingerprint localization technique, and presents the method of describing signal fingerprint database and location estimation by using mathematical model.
