In this paper, based on circle detection and fitting, an accurate long-distance positioning system using laser range finders (LRFs), is proposed. To utilize orientation-invariant property of the circle, a cylinder shaped bar is chosen as the reference target of the positioning system. After obtaining the arc shaped contour of the cylindrical target scanned from LRF, given the prior information of...
In this paper, inspired by RANSAC and Hough Transform voting procedure, a modified RANSAC algorithm of detection of cylindrical reference target using LRF for positioning system is proposed. Utilizing the orientation-invariant property of the circle, cylindrical shaped bar is chosen as the reference target of the positioning system. The given radius of the cylinder and convex arc shaped contour observed...
