随着室内定位技术的广泛应用,对定位精度的要求越来越高,传统的LANDMARC算法已不能满足实际应用的需求,因此,结合传统的LANDMARC算法和质心算法,提出一种改进的LANDMARC算法。首先利用MATLAB进行了理论仿真,研究发现改进的LANDMARC算法在参考标签间隔在0~5 m时,定位精度要优于传统经典算法,且定位精度最大可提高35.4%。其次使用ZigBee定位系统进行了实验测量,研究发现实验测量结果与理论仿真结果基本吻合。
With the wide application of indoor positioning technology, the requirements for positioning accuracy are getting higher and higher. The traditional LANDMARC algorithm can not meet the needs of practical applications. Therefore, an improved LANDMARC algorithm is proposed based on the traditional LANDMARC algorithm and centroid algorithm. Firstly, MATLAB is used to simulate the theory. The results show that the improved LANDMARC algorithm is better than the traditional algorithm when the reference label interval is between 0 ~ 5 m, and the maximum precision can be increased by 35.4%. Secondly, the ZigBee positioning system was used to conduct the experimental measurement. The experimental results show that the experimental results are in good agreement with the theoretical simulation results.
