Title
(EN) METHOD FOR RECOGNIZING POSITION AND CONTROLLING MOVEMENT OF A MOBILE ROBOT, CAPABLE OF MINIMIZING COMPUTATIONAL COMPLEXITY AND LOCATION RECOGNITION ERROR
(KO) 이동 로봇의 위치 인식 및 주행 제어 방법과 이를 이용한 이동 로봇
Abstract
(EN)
PURPOSE: A method for recognizing position and controlling movement of a mobile robot is provided to control the movement of a robot by detecting the location of the robot through matching of images. CONSTITUTION: A mobile robot comprises an image acquisition unit(12), a sensor unit(42), an image processing unit(20) and a microprocessor(30). The sensor unit acquires the driving information including movement direction and distance of a robot. The image processing unit processes the acquired image and extracts feature points in order to produce the descriptor about the feature point. COPYRIGHT KIPO 2011
