基于改进克里金插值的室内定位位置指纹库构建方法
Construction method of fingerprint database based on improved Kriging interpolation for indoor location
摘要
Abstract
In today's society,the demand for location-based services,especially indoor location services,is becoming more and more urgent.Using the indoor wireless signal intensity to locate,the location fingerprint method has the advantages of convenience,low cost,and so on.But it will take a lot of manpower and time to build a fine-grained fingerprint database.In order to improve the efficiency,this paper proposes a method for constructing the database based on improved Kriging interpolation.The simulated annealing algorithm is used to improve the theoretical variogram fitting accuracy,and then the signal strength at the unmeasured points is estimated with measurement data.Compared with the inverse distance weighted interpolation and traditional Kriging interpolation,experimental results show that this method can not only effectively improve the construction efficiency and precision of interpolation fingerprint database,but also reduce the artificial workload of fingerprint data acquisition by 50％.关键词
