基于观测源加权的三边定位改进算法
Research on Trilateral Localization Algorithm Based on Observation Source Weighting
摘要
Abstract
Aiming at the problem that the RFID localization technology based on the trilateral positioning algorithm has large localization errors and poor system stability in the indoor environment,this paper proposes an improved trilateral positioning algo-rithm based on observation source weighting.The algorithm selects the nearest three points after the RSSI ranging,and obtains the coarse localization coordinates through the trilateral localization algorithm and the weighting algorithm.Then,the coarse localization coordinates are used to calculate the corresponding deviation reliability weight through the observation source.Finally,the coordi-nates of the label to be located are obtained by weighting.The experiment results show that the localization accuracy of the TLOW al-gorithm is improved by 26.18%,and the system stability is improved by 38.45%compared with the trilateral localization algorithm.In the indoor environment,the TLOW algorithm has good applicability and can meet the basic needs of indoor localization.关键词
