主 题:3D indoor localization fingerprint fusion positioning time-difference of arrival pedestrian dead reckoning received signal strength
摘 要:In this paper,an effective target locating approach based on the fingerprint fusion posi-tioning(FFP)method is proposed which integrates the time-difference of arrival(TDOA)and the received signal strength according to the statistical variance of target position in the stationary 3D *** FFP method fuses the pedestrian dead reckoning(PDR)estimation to solve the moving target localization *** also introduce auxiliary parameters to estimate the target motion ***,we can locate the static pedestrians and track the the moving *** the case study,eight access stationary points are placed on a bookshelf and hypermarket;one target node is moving inside hypermarkets in 2D and 3D scenarios or stationary on the *** compare the performance of our proposed method with existing localization algorithms such as k-nearest neighbor,weighted k-nearest neighbor,pure TDOA and fingerprinting combining Bayesian frameworks including the extended Kalman filter,unscented Kalman filter and particle fil-ter(PF).The proposed approach outperforms obviously the counterpart methodologies in terms of the root mean square error and the cumulative distribution function of localization errors,espe-cially in the 3D *** results corroborate the effectiveness of our proposed approach.
