LOCALIZATION SYSTEM OF MOBILE ROBOT BASED ON CAMERA AND LANDMARKS AND METHOD THERE OF

摘要

A localization system and method of a mobile robot using a camera and a mark are provided to automatically calculate the distance between nodes to create a topology map by using a newly installed mark as a node. A localization system of a mobile robot using a camera and a mark includes n marks(200), a camera(110), a mark detector(120), a robot location detector(130), a mark location estimating part(140), a topology map creator(150), and a robot controller(160). The n marks have a wireless communication function. The camera photographs the marks. The mark detector detects at least two of the marks. The robot location detector calculates the location of a mobile robot(100) by using the detected marks. The mark location estimating part calculates the location of a new mark on absolute coordinates. The topology map creator creates a topology map of the mobile robot by using the calculated location of the new mark. The robot controller controls traveling of the mobile robot by using the topology map.
