In order to reduce the complexity of the material handling operation, we have developed a method based on the integration of 2-D range data of Poraloid ultrasonic sensor along with 2-D visual data of an optical camera. Data obtained from the two separate sources complements each other and is used in an efficient algorithm to control this robotically assisted field material handling system. Range data obtained from two linear scannings is used to determine the pan and tilt angles of of a pallet using least mean square method. Then, 2-D visual data is used to determine the swing angle and. © 1988 IEEE. |
