To provide an operation terminal that improves convenience of an operation terminal and enables intuitive operation of a work vehicle.SOLUTION: An operation system includes: a projection device 2 that projects at least one of a figure, a mark and a character on an object; a photographing device 3 that photographs the figure, the mark and the character projected on a wall surface W of the object; a position detecting device 4 that detects a position and a direction of a work device as well as a position and a direction of the projection device 2 relative to the photographing device 3; a terminal control device 7 that calculates a distance from the projection device 2 to the wall surface W of the object and a shape of the wall surface W, based on a position and a direction of the projection device 2 relative to the photographing device 3 and based on differences in shape between the figure, the mark and the character projected on a virtual projection surface V separated by a reference distance Ds from the projection device 2 and the figure, the mark, and the character projected on the wall surface W of the object; and a moving operation tool 6 that transmits a control signal to an actuator of the work device from the terminal control device 7.SELECTED DRAWING: Figure 6

    【課題】操作端末の利便性を向上させ、直感的に作業車両を操作することができる操作端末の提供する。【解決手段】対象物に図形、印または文字のうち少なくとも一つを投影する投影装置2と、前記対象物の壁面Wに投影された前記図形、前記印および前記文字を撮影する撮影装置3と、前記作業装置の位置および方向と、撮影装置3に対する投影装置2の位置および方向とを検出する位置検出装置4と、撮影装置3に対する投影装置2の位置と方向、および投影装置2から基準距離Dsだけ離隔した仮想の投影面Vに投影された前記図形、前記印および前記文字に対する前記対象物の壁面Wに投影された前記図形、前記印および前記文字の形状の違いから、前記投影装置2から前記対象物の壁面Wまでの距離および壁面Wの形状を算出する端末制御装置7と、端末制御装置7から前記作業装置のアクチュエータに制御信号を送信させる移動操作具6と、を備える。【選択図】図6
