<P>PROBLEM TO BE SOLVED: To provide an image generation system capable of presenting useful image information to an operator who operates a crane while looking down at the circumference of a hook obliquely from the vertically upper side. <P>SOLUTION: The image generation system includes: a camera installed on a ceiling crane to image an adjacent ceiling crane, the camera having an optical axis extending in parallel to a traveling direction of the ceiling crane; and a scale drawing means which draws a scale indicating a plurality of crane-to-crane distances on images taken by the camera, based on a fixed distance between a target point included in a mark moving together with the ceiling crane in a direction parallel to the optical axis and the optical axis in a plane vertical to the optical axis and the on-the-image magnitude of the fixed distance in an image which is taken by the camera when the crane-to-crane distance from the ceiling crane to the ceiling crane is a predetermined value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
