To allow an operator of a cargo handling vehicle to easily determine whether or not a cargo contacts an adjacent object.SOLUTION: An operation support device of a cargo handling vehicle comprises: a camera; an image processing unit; a vehicle side wireless machine; a stereo camera; a second wireless machine; a display controller; and a monitor. The image processing unit extracts a point cloud being the set of points expressing a portion of an object as the object in a coordinate system on a real space. The image processing unit derives a cargo handling space occupied by a cargo during the cargo handling work by a cargo handling gear in the coordinate system on the real space. The image processing unit derives the dimension of clearance between the cargo handling space and an adjacent object. The display controller displays on the monitor a symbol according to the dimension of the clearance so as to be superimposed on a photographed image that is photographed by the camera.SELECTED DRAWING: Figure 6

    【課題】荷と隣接物体とが接触するか否かを荷役車両の操作者が判別しやすくすること。【解決手段】荷役車両の操作支援装置は、カメラ、画像処理部、車両側無線機、ステレオカメラ、第2無線機、表示コントローラ、及びモニタを備える。画像処理部は、実空間上の座標系において、物体の一部を表す点の集合である点群を物体として抽出する。画像処理部は、実空間上の座標系において、荷役装置による荷役作業中に荷が占有する荷役空間を導出する。画像処理部は、荷役空間と隣接物体とのクリアランスの寸法を導出する。表示コントローラは、カメラによって撮像された撮像画像に重畳して、クリアランスの寸法に応じたシンボルをモニタに表示する。【選択図】図6
