摘　　要：目的将低成本的RFID标签应用于建筑内环境定位中,解决建筑内环境中定位精度低,成本高的问题.方法采用LANDMARC算法和质心算法在三维空间相结合的方法,并且将参考标签对称分布于空间上下层,进而提高建筑内环境的定位精度.结果仿真结果表明,该算法的平均误差为0.41 m,并且以概率60%地分布在0.6 m的范围内.结论三位质心定位算法可以较好地实现待定位标签的空间定位,突破了以往二维平面定位的局限性.The inexpensive RFID tags were used for location in building environment to solve the problem of low location precision and high cost in building environment location. In this work, the combination of LANDMARC algorithm and centroid algorithm in three-dimensional space was used. Simultaneously, the reference tags were distributed symmetrically in upside and downside of the space to enhance the location precision in building environment location. Simulation results show that the algorithm used in this work could realize the space location of tracking tags better, and solve the problem of limitation of anciently tow-dimensional space location.
