Abstract: A LiDAR included in this automatic docking device measures the distance to a surrounding object at each predetermined angle by irradiating the object with light and receiving the light reflected by the object. When a ship offshore is instructed to perform automatic docking, the ship navigates to some extent by automatic navigation based on satellite positioning, and is then switched to automatic navigation based on the LiDAR. Before switching to the automatic navigation based on the LiDAR, the LiDAR performs preparatory measurement for measuring the distance to an object around a docking position. In this preparatory measurement, a control unit controls to change, for example, the orientation of the ship such that light emitted from the LiDAR can be reflected by the object around the docking position and can be received by the LiDAR.
