  • Publication number: 20260044157
    Abstract: A ship docking assistance device includes a position azimuth information acquisition unit; a LIDAR; a map generation updating unit; a high-point acquisition unit; and a position azimuth estimation unit. The LIDAR acquires point-group data three-dimensionally indicating the environment around a ship. The map generation updating unit generates a map around the ship based on the point-group data. The high-point acquisition unit acquires, from within the point-group data, a high point having a prescribed height or more. The position azimuth estimation unit estimates the position and the azimuth of the ship through matching between the position of the high point acquired by the high-point acquisition unit and the position of the high point in the map. The map generation updating unit updates the map by placing the point-group data in the map using, as references, the position and the azimuth of the ship estimated by the position azimuth estimation unit.

  • Publication number: 20240326962
    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.

  • Publication number: 20220028278
    Abstract: According to the present invention, a route controller generates a route that makes a ship dock at a berthing facility. The route includes a first location and a second location (P2). The first location is a via point that is offset a prescribed distance in a direction that is orthogonal to the direction in which the berthing facility is oriented from a docking point for the ship at the berthing facility. The second location is the docking point for the ship at the berthing facility. The first location is immediately before the second location in the sequence to be realized by the ship. The route is generated such that the ship remains oriented in the direction in which the berthing facility is oriented as the ship moves from the first location to the second location.
