针对室内定位与定向系统,提出了一种结合粒子群优化(PSO)和天牛须搜索(BAS)的VLC室内定位与定向算法,通过PSO算法探索接收端的最优方向,利用BAS算法对每个粒子当前方向下的最佳三维坐标进行搜索。首先在3 m×3 m×5 m的室内空间和40 dB信噪比下进行仿真研究,所提出的VLC室内定位与定向系统实现了平均定位误差4.82 cm和平均定向误差2.24°的性能指标。然后在0.9 m×0.9 m×1.5 m的实验系统中,实施了同时定位与定向的实验验证,平均定位与定向误差分别为5.32 cm 与5.99°。相比传统VLC室内定位方案,所提 VLC 室内定位与定向系统不需要接收端高度和方向的先验知识,大大降低了使用复杂度,具有更加广泛的应用场景。
For the insufficient research on the simultaneously positioning and orientating system
a VLC positioning and orientating algorithm based on combining particle swarm optimization (PSO) and beetle antennae search (BAS) was proposed.The PSO algorithm was used to explore the optimal direction of the receiver and meanwhile the BAS algorithm was used to search the best three-dimensional coordinates of each particle in the current direction.Firstly
the indoor space of 3 m×3 m×5 m and the SNR of 40 dB were assumed in the simulation
the proposed VLC indoor positioning and orientating system could achieve the average positioning error of 4.82 cm and average orientating error of 2.24°.Then
in the laboratory space of 0.9 m×0.9 m×1.5 m
the experimental demonstration was accomplished for the first time
and the average positioning and orientating errors of this experimental system were 5.32 cm and 5.99°
respectively.Compared with the traditional VLC indoor positioning schemes
the proposed VLC positioning and orientating system does not need the prior knowledge of the height and direction of the receiver
which greatly reduces the system complexity and is applicable to a wider range of applications.
