单灯带信标可见光定位系统

可⻅光定位（VLP）具有定位精度⾼、成本低等优点，正在成为⼀种很有前景的实⽤室内定位系统解决⽅案。但是，⼤多数 VLP 系统需要⾄少两个 VLP LED 灯才能进⾏准确的位置计算。因此，VLP 在实际场景中的应⽤可能会因为这个限制⽽受到限制。在本⽂中，我们提出了⼀种快速且⾼精度的基于单 LED 的 VLP 系统。⾸先，提出了⼀种不平衡的单LED VLP算法，以提⾼定位精度并降低计算复杂度。其次，提出了⼀种快速信标搜索算法，以进⼀步减少每个捕获图像的处理时间。最后，由于所提出的算法具有精度⾼、复杂度低的优点，所提出的系统也可以在低端硬件平台上实现。实验结果表明，该系统在3 m⾼处的平均定位误差降低到2.26 cm，在笔记本电脑上的平均定位时间降低到6.3 ms，在低端嵌⼊式平台上的平均定位时间降低到60 ms。Visible Light Positioning (VLP) has advantages such as high positioning accuracy and low cost, and is emerging as a promising practical indoor positioning system solution. However, most VLP systems require at least two VLP LED lamps to perform accurate position calculation. Consequently, the practical application of VLP may be restricted by this limitation. In this paper, we propose a fast and high-precision single-LED-based VLP system. First, an unbalanced single-LED VLP algorithm is proposed to improve positioning accuracy and reduce computational complexity. Second, a fast beacon search algorithm is proposed to further reduce the processing time of each captured image. Finally, due to the high accuracy and low complexity of the proposed algorithms, the proposed system can also be implemented on low-end hardware platforms. Experimental results show that the average positioning error of the system is reduced to 2.26 cm at a height of 3 m, the average positioning time on a laptop is reduced to 6.3 ms, and the average positioning time on a low-end embedded platform is reduced to 60 ms.
