目前的定位技术主要是基于全球定位系统(GPS)的室外定位技术,如果在室内,GPS的误差会比较大。传统方式采用摄像头采集图像,通过算法进行定位,但是其成本高,应用比较复杂,因此本文设计了一款基于可见光通信的定位机器人,采用ROS系统进行开发,通过可见光通信获取位置,通过光照传感器得到靠近或者远离目标的位置,最终实现在室内进行定位。

The positioning technology in life is mainly based on the global positioning system (GPS) outdoor positioning technology,if the indoor GPS error will be quite large.The traditional way uses the camera to collect images and the algorithm to locate,but its cost is high,the application is more complex,can not be widely used.In this paper,a positioning robot based on visible light communication is designed.The ROS system is used for development.The position is obtained through visible light communication,and the position near or far from the target is obtained through light sensor.Finally,it can be positioned indoors.
