Research on a robot landmark localization system based on monocular camera

Robot localization is very important for the researching of intelligent robotics. The accurate of the robot coordinate will influence the control accuracy of the robot's moving action. So, it is essential for robot itself to have the ability to realize the modifying of coordinate of its own in real time when it is moving. In this paper, a robot landmark localization system based on a monocular camera is researched theoretical and experimental. Three longitudinal landmarks are used to assure the robust of the system. Digital image processing technology is enrolled to revise the image stretching and decrease the disturbing of noise. The experiments based on Pioneer III mobile robot show that this system can work well at different topographic situation without lose of signposts.
