一种改进的三边定位算法

An Improved Trilateral Positioning Algorithm

RFID无线定位技术因系统易于实现、硬件成本低等优点,已被广泛应用于各种室内定位领域。在RFID定位算法中,三边定位算法因其算法简单、易于编程实现,因此在实际定位问题中被广泛采用,但是传统的三边定位算法受环境中的不确定因素影响较大,定位精度较低,因此本文提出一种基于相交法的三边定位改进算法,在一定程度上提高了定位精度。实验结果验证了本文算法的可行性及优越性。

RFID wireless positioning technology has been widely used in various indoor positioning fields due to the advantages of easy implementation of the system and low hardware costs.In RFID positioning algorithm,the trilateral positioning algorithm is widely used in practice because of its simple algorithm and easy programming.However,the traditional trilateral positioning algorithm is strongly influenced by uncertainties in the environment and therefore has lower accuracy.In this paper,a trilateral positioning algorithm based on the intersection method is proposed in order to improve the positioning accuracy to a certain extent.The feasibility and superiority of the proposed algorithm are confirmed by experimental results.
