一种面向智能终端的可见光室内定位技术
首发时间:2016-12-06
摘要:针对室内位置服务需求日益增加,室内定位精度和定位稳定性更是成为关键性问题,基于WIFI和蓝牙的室内定位技术,显然已经越来越不能满足室内服务的需求。因此,本文主要研究,面向智能终端的可见光室内定位技术。使用发光二极管(Light-emitting Diode, LED)作为照明工具的场景越来越多,在足够多的LED灯作为可靠信标时,通过可见光通信(Visible Light Communication, VLC)让可见光可以携带数字信息,结合光辐射衰减模型,最终可以得到位置室内信息。面向智能终端的可见光室内定位技术不但可以节省花销,而且可见光的抗干扰能力远远高于其他射频信号,该方法提高了室内定位的准确性和稳定性。实验结果表明,面向智能终端的可见光室内定位技术的定位精度在0.8m~1.2m之间,稳定性在96.3%以上。?????

A Visible Light Indoor Positioning Technology for Intelligent Terminal
Abstract:For indoor location service demand is increasing, the indoor positioning precision and stability has become the key problem of indoor positioning technology based on WIFI and Bluetooth, apparently has been increasingly unable to meet the demand of indoor service. Therefore, the main research of this paper, the intelligent terminal of the visible light indoor positioning technology. A light emitting diode is used as a lighting tool in the scene more and more, LED light enough as a reliable beacon, through visible light communication for visible light with digital information, combined with the optical radiation attenuation model, can be obtained by indoor location information. The visible light indoor positioning technology for intelligent terminal not only can save cost, but also has the ability to resist interference of visible light is much higher than other radio frequency signals, this method improves the accuracy and stability of indoor positioning. The experimental results show that the positioning accuracy of the visible light indoor positioning technology based on intelligent terminal is between 0.8m ~ 1.2m, and the stability is more than 96.3%.
