JPS6488104A - Method and device for detecting center position of article - Google Patents

Abstract

PURPOSE:To accurately detect the center of a coil without making a stop position highly accurate by picking up an image of the end surface of a cylindrical contour while moving a telecamera up and down, and right and left, and computing the center position of the article from the position relation between the camera and article. CONSTITUTION:The industrial telecamera 13 is provided on a frame 21 so that it can be moved up and down, and right and left by a traveling driving device 23 and an elevation driving device 27. The video signal of the camera which is obtained by picking up the end surface of the coil 13 conveyed by a conveyance vehicle 12, the distance signal of an ultrasonic sensor 33 regarding the distance to the coil 13, and camera position signals from a traveling position detector 34 and an elevation position detector 35 are inputted to a control computer 36. The computer 36 calculates the center position of the coil 13 from those input signals, so the coil center position is accurately detected without making the vehicle stop position highly accurate and the operation of a handling crane 1 is securely automatized.
