| 摘要: |
| 在分析基于RSSI的LANDMARC定位系统及算法的基础上,提出了一种改进三角区域定位方法,消除了远距离不良参考标签对定位精度的影响。同时,在布置有大量阅读器的场合,该法可有效减少计算量。Matlab仿真结果表明,该算法具有更高的定位精度。 |

| Abstract: |
| This paper briefly introduced some common indoor positioning technologies and analyzed the LANDMARC system which is based on RSSI and its algorithm. On the basis of it, we proposed a triangle region positioning method which can eliminate the bad influence on the positioning precision produced by the long-range reference labels and effectively reduces the amount of computation when there are a large number of readers. The simulation results obtained with MATLAB and their analysis show preliminarily that the algorithm proposed in this paper gives higher precision. |
