快速移动可见光定位系统

实时性是影响室内定位系统实⽤性的关键因素。虽然可⻅光定位 (VLP) 因其可以通过 LED 照明提供室内定位功能⽽被⼴泛研究，但现有的 VLP 系统仍然存在定位延迟⾼的问题，并且不适⽤于具有⾼移动速度的移动单元。本⽂提出了⼀种定位延迟低、定位精度⾼的实时VLP系统。通过轻量级图像处理算法，该系统可以在低成本的嵌⼊式系统上实现，并⽀持快速移动单元的实时精确室内定位。实验结果表明，所提出的系统在树莓派上实现可以达到 3 的定位精度。

Real-time performance is a critical factor affecting the practicality of indoor positioning systems. Visible Light Positioning (VLP) has been extensively researched as it enables indoor positioning via LED lighting. However, existing VLP systems still suffer from high positioning latency and are not suitable for mobile units with high moving speeds. This paper proposes a real-time VLP system with low positioning latency and high positioning accuracy. Equipped with lightweight image processing algorithms, the system can be implemented on low-cost embedded systems and supports real-time and accurate indoor positioning for fast-moving mobile units. Experimental results demonstrate that the proposed system, when implemented on a Raspberry Pi, achieves a positioning accuracy of 3.
