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.

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.

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.

Abstract

A field shape identification unit in a server control unit identifies, on the basis of position information about a work vehicle, the shape of a work field through which the work vehicle has traveled while working. A degree-of-overlap determination unit in the server control unit compares the shape of the work field identified by the field shape identification unit to the shape of a reference field and determines whether the degree of overlap between the work field and the reference field is greater than or equal to a prescribed degree. When the degree-of-overlap determination unit determines that the degree of overlap between the work field and the reference field is equal to or greater than a prescribed degree, an information management unit associates work-related information pertaining to the work in the work field with the reference field and manages the same.

Abstract

An autonomous travel system is provided with a location acquisition unit, an inertia measuring device, a travel control unit, an initialization control unit, and a condition setting unit. The location acquisition unit acquires a location of a work vehicle by using a satellite positioning system. The inertia measuring device detects an orientation of the work vehicle. The travel control unit causes the work vehicle to travel autonomously along a preset travel route. The initialization control unit carries out an initialization process for the inertia measuring device by obtaining the orientation of the work vehicle on the basis of a value acquired by the location acquisition unit during initialization travel in which the work vehicle travels straight in a predetermined direction. In the condition setting unit, switching from off to on of a power source of the work vehicle is defined as a first starting condition for the initialization process, and acceptance of an instruction for carrying out the initialization process when the power source of the work vehicle is on is defined as a second starting condition for the initialization process.
