一种基于轨迹指纹优化的室内定位算法
An Indoor Positioning Algorithm Based on Trajectory Fingerprint Optimization
摘要
Abstract
For the reducing of fingerprint data quality ,this paper proposes a novel trajectory fingerprint‐based data structure to replace the original single fingerprint .While compatible with existing fingerprint positioning framework ,this paper carried out the trajectory modeling to tra‐ditional off‐line fingerprint database ,and the trajectory mapping of real‐time online collected fin‐gerprint .The experimental results further show that the positioning algorithm based on trajecto‐ry fingerprint can improve the positioning accuracy by approximately one fold ,and the positio‐ning performance is superior to other single point fingerprint algorithms .关键词
