A Robust Real-time Technique for Line Extraction
Xiaoping Chen · Jisuanji fangzhen · 2008
Vision system plays an important role as the communication bridge between robot and its environment.The robot should be real-time and robust for the variable environment.Straight lines are very important intermediate level symbol in image analysis.There are many approaches for extracting straight lines,but they all have their particular drawbacks limiting their use for robot.A new method,which detects the lines quickly and robust,is devised in this issue.The experimental results show that it's better than traditional methods for its speediness and adjustability.In the last part,the application in RoboCup 4-legged league is presented,i.e.detection of lines of the match field,and detection of ellipse and corners based on this line detection.
