一种基于视觉信息的可见光通信室内定位方法
An Indoor Positioning Method of Visible Light Communication Based on Visual Information
摘要
Abstract
The development of visible light communication provides a new opportunity for indoor positioning. In order to improve indoor positioning accuracy,a positioning method using visible light communication based on visual light information is proposed,which is fu-sing visible light information received by low-resolution photo diode array and visual information received by front facing camera to real-ize the indoor positioning. At the same time,a fusion method for two different information matching is discussed,and for the relationship between the front facing camera and the LEDs’ imaging,an improved collinear equation model is proposed. When the input data is the visible light information,the relevant visual information and the parameters of front facing camera from LEDs’ light,the 3D coordinate information of the mobile terminal is obtained by using the model. A hardware-in-loop simulation has been verified and analyzed. Ac-cording to the results of the simulation,3D positioning accuracy is up to decimeter level.关键词
