摘要
为提高室内三维定位系统的性能,提出一种基于区域划分和目标搜索的室内RFID三维定位算法.通过布置在室内顶部和侧面的参考标签划分一个待定位标签所在的区域,选取该区域中心点作为目标搜索的初始点,向x,y,z轴正负方向对待定位标签进行搜索,通过不断逼近,最终确定待定位标签的坐标.仿真实验表明,该算法定位误差小,稳定性优良.
To improve the performance of three-dimensional indoor RFID positioning system,three-dimensional interior positioning algorithm is proposed based on the region division and target searching.Firstly,an area is divided where the target label will be by the reference labels which are arranged at the top and side in the room.Secondly,the central point of the area is picked as a starting point to search target with fixed step along the coordinate axis in X,Yand Zdirections.By the successive approximation,the coordinates of the target label are found.The simulation results show that the algorithm has small errors in positioning and is more accurate.
