摘　　要：作为一种常见的室内定位方法,Wi-Fi指纹定位通常包含离线建库和在线定位两个步骤。目前,受信号强度RSSI不稳定的影响,Wi-Fi指纹定位方法在离线阶段的指纹采集及在线定位阶段的位置定位中均存在一定的偏差。文章围绕Wi-Fi指纹定位的指纹建库和指纹匹配,对现有的Wi-Fi指纹定位关键技术进行了阐述,并对离线阶段的位置指纹库建立技术、在线定位阶段的指纹匹配技术的研究现状及发展前景进行了研究。As a common indoor positioning method,Wi-Fi fingerprint localization usually involves two steps:offline database building and online localization.At present,due to the unstable RSSI signal strength,there are certain deviations in the Wi-Fi fingerprint positioning method in both offline fingerprint collection and online localization stages.This article focuses on the establishment of fingerprint databases and fingerprint matching for Wi-Fi fingerprint localization,elaborates on the key technologies of existing Wi-Fi fingerprint localization,and studies the current research status and development prospects of position fingerprint database establishment technology in the offline stage and fingerprint matching technology in the online positioning stage.
