摘 要：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。

Abstract: 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 ap-
plicable to a wider range of applications.
Key words: visible light communication, indoor positioning and orientating, received signal strength, particle swarm op-
