基于LED照明灯光的可见光室内停车场定位导航系统

Visible light indoor parking lot positioning navigation system based on LED lighting

摘要: 室内停车场是静态交通的一个重要组成部分，由于缺乏有效的室内定位技术，目前存在着泊车导航以及反向寻车困难的问题。提出一种基于LED照明灯光的可见光室内停车场定位导航系统，实现了面向车辆的停车位引导和面向行人的反向寻车导航，具有定位速度快、定位精度高和"照明定位两用"的优势。实验结果及现场测试表明：该系统定位精度可达到7.5 cm，可支持车辆或行人在时速达17 km/h下的实时定位导航。

Abstract: Indoor parking lot is an important part of static traffic; however, because of the lack of effective indoor positioning technology, there are currently problems in parking navigation and reverse car finding. This paper proposes a visible light positioning and navigation system for indoor parking lot based on LED lighting, which realizes parking navigation for vehicle and reverse car finding for pedestrian. It has the advantages of fast positioning speed, high positioning accuracy and "lighting and positioning dual use". The experimental results testing on the spot shows that the highest positioning accuracy of system can reach 7.5 cm and the system can support positioning and navigation at speed up to 17 km/h for vehicles or pedestrians.
