ABSTRACT:
A camera19picks up an image of a cargo handling target and acquires image data of a mark affixed to the cargo handling target. An image processing section66performs image recognition of the mark and acquires the position and size of the mark in a screen coordinate system. A real coordinate position calculating section77acquires the position of the camera19in a real coordinate system based on the obtained position and size of the mark. Based on the position of the camera19,a deviation amount calculating section78acquires a deviation amount between the current position of forks and a target position. A cargo handling control section50executes automatic positioning control of the forks in such a way that the deviation amount becomes zero.
