摘要
该文提出了一种基于Wi-Fi指纹和LED光学特性的室内定位系统,将Wi-Fi指纹和光学特性的色温和频率信息进行组合定位.使用光学特性提高Wi-Fi指纹定位的精准度.将需要定位的区域划分为多个相同的小区域,并在整个区域上构建稀疏的Wi-Fi指纹地图.通过Wi-Fi指纹定位确定目标所在的小区域.在小区域内通过光学信息的光照强度和频率信息进行精准定位.最后,通过设计实验和仿真结果表明,在室内环境中,该系统实现了平均误差为0.97 dm的定位,能够有效地定位.
Abstract
This paper introduces an indoor positioning system based on Wi-Fi fingerprinting and LED optical charac-teristics,integrating the color temperature and frequency information of both Wi-Fi fingerprinting and optical features for combined positioning.Optical characteristics are employed to enhance the accuracy of Wi-Fi fingerprinting posi-tioning.The area that requires positioning is divided into multiple identical sub-areas,and a sparse Wi-Fi fingerprint map is established across the entire region.The specific sub-area where the target is located is identified using Wi-Fi fin-gerprint positioning.Precise positioning within the sub-area is achieved using optical information related to light inten-sity and frequency.In conclusion,through designed experiments and simulation results,it shown that in indoor settings,this system achieves a positioning with an average error of 0.97 dm,demonstrating its effective positioning capability.
