【摘要】 在智能空间三维定位过程中,由于噪声干扰,对未知节点的定位会产生误差。通过对定位过程中产生的误差区域分析,推导出当空间定位参考点和未知节点满足一定条件时,定位误差最小,由此提出空间定位参考点的布局模型定理。仿真实验表明,定位参考点布局模型定理能更好地满足对智能空间实时定位的需求,且具有较高的定位精度。更多还原

【Abstract】 Due to the noise interference, distance errors of unknown node can be occurred in the 3-D smart space.The errors due to positioning an regional are studied, and some conclutions are deduced that errors of uknown node are smallest when positioning reference nodes and unknown node meet certain conditions.Thus, the layout model theorem of space positioning refrence nodes is proposed.Simulation results indicate that the positioning reference point placement theorems can meet the requirement of samrt terminal’s real-time positioning and possesses the preferable positioning precision.更多还原
