Summary: | PROBLEM TO BE SOLVED: To allow an operator of a crane to instantaneously recognize a moving direction of a hook displayed on a display unit of an image display device.SOLUTION: An image display device includes: a display unit 10 for displaying an image P that is captured by a monitoring camera 300 mounted on a boom of a crane and includes a hook hung from the boom with a wire rope; an operational signal acquiring unit 20 for acquiring operational signals S output by an operation input to an operating unit 820 for moving the hook; and a moving direction calculating unit 30 for calculating a moving direction of the hook relative to a horizontal plane by an operation input to the operating unit 820 on the basis of the operational signals S acquired by the operational signal acquiring unit 20. The display unit 10 displays a mark representing the moving direction of the hook calculated by the moving direction calculating unit 30 together with an image of the hook.SELECTED DRAWING: Figure 3
【課題】画像表示装置の表示部に表示されたフックの移動方向を、クレーンのオペレータに瞬時に認識させる。【解決手段】クレーンのブームに設けられた監視カメラ300で撮影され、ブームからワイヤロープで吊り下げられたフックを含む画像Pを表示する表示部10と、フックを移動させる操作部820に入力された操作により出力された操作信号Sを取得する操作信号取得部20と、操作部820に入力された操作により、水平面に対するフックの移動方向を、操作信号取得部20により取得された操作信号Sに基づいて求める移動方向算出部30と、を備え、表示部10は、移動方向算出部30により求められたフックの移動方向を特定する印を、フックの画像とともに表示する。【選択図】図3 |
