MOBILE ROBOT NAVIGATION BASED ON CIRCLE RECOGNITION

Peter Pásztó – Peter Hubinský

   This paper presents a navigation method for a mobile robot using a visual system. Circular marks with specific colors are used for marking the significant points of the mobile robot's trajectory that it needs to pass. The colors of the used marks are signalizing the way of their bypassing with the mobile robot (from the left or right side). The mobile robot uses only one camera for the marks recognition task and it is able to determine its own relative position from the detected marks. The image processing and the mobile robot's trajectory planning algorithm working in real-time are described in this paper.

Keywords: circular mark detection, mobile robot trajectory planning, image processing, Hough transform
