Abstract

A route display device is provided. The device includes an acquirer installed in a movable body and configured to acquire a position and a direction of the movable body. The device also includes a route memory configured to store a route with a plurality of waypoints. The device also includes a display unit including a display screen having a linear route display section and configured to linearly display the route in a vertical axis of the linear route display section and positional relation of either one of the movable body and one or more targets with respect to the route in left-and-right directions of the route in a horizontal axis of the linear route display section. The device also includes a display controller configured to control a display position of either one of the movable body and the target with respect to the route.

Claims

1. A route display device, comprising:

an acquirer installed in a movable body and configured to acquire a position and a direction of the movable body;

a route memory configured to store a route with a plurality of waypoints;

a display unit including a display screen having a linear route display section and configured to linearly display the route in a vertical axis of the linear route display section and positional relation of either one of the movable body and one or more targets with respect to the route in left-and-right directions of the route in a horizontal axis of the linear route display section; and

a display controller configured to control a display position of either one of the movable body and the one or more targets with respect to the route.

2. The route display device of claim 1, wherein when the movable body is off the route, the display controller displays the movable body separated from the route, corresponding to the positional relation of the movable body with the route.

3. The route display device of claim 1, wherein the display controller displays the movable body corresponding to the acquired direction of the movable body.

4. The route display device of claim 1, wherein the display controller displays, in the linear route display section, among the one or more targets, the target that has a possibility of colliding with the movable body traveling along the route, in either one of the same and different display mode with respect to a display mode of other target.

5. The route display device of claim 1, wherein the display controller controls the horizontal and vertical axes of the linear route display section to indicate distance, and

wherein a display range of the vertical axis is wider than a display range of the horizontal axis.

6. The route display device of claim 1, wherein the display controller controls the horizontal axis of the linear route display section to indicate distance and the vertical axis of the linear route display section to indicate time.

7. The route display device of claim 1, wherein the display controller displays, in the linear route display section, a movable body mark indicating a current position of the movable body and a reference mark that moves along the route according to a time schedule for the movable body to travel on the route.

8. The route display device of claim 1, wherein the movable body is a ship.

9. The route display device of claim 1, wherein the display controller displays, in the linear route display section, positional information of a beacon.

10. The route display device of claim 1, wherein the display controller displays, in the linear route display section, positional information of a channel buoy.

11. The route display device of claim 1, wherein the display controller displays, in the linear route display section, a course-changing point indicating a timing of starting to change, after the movable body passes a waypoint, a course of the movable body to the next waypoint.

12. The route display device of claim 11, wherein, in addition to the course-changing point, information indicating the course changing direction is displayed in the linear route display section.

13. The route display device of claim 1, wherein the display controller displays a dangerous zone in the linear route display section.

14. The route display device of claim 13, wherein the dangerous zone is a shallow bottom zone.

15. A route display method, comprising:

acquiring a position and a direction of a movable body; and

linearly displaying the route in a vertical axis of a linear route display section of a display unit and positional relation of either one of the movable body and one or more targets with respect to the route in left-and-right directions of the route in a horizontal axis of the linear route display section of the display unit.

16. The route display method of claim 15, wherein when the movable body is off the route, the movable body mark is displayed to be separated from the route, corresponding to the positional relation of the movable body with the route.

17. The route display method of claim 15, wherein the movable body mark is displayed corresponding to the acquired direction of the movable body.

18. The route display method of claim 15, wherein the horizontal and vertical axes of the linear route display section indicates distance, and

wherein a display range of the vertical axis is wider than a display range of the horizontal axis.

19. The route display method of claim 15, wherein the horizontal axis of the linear route display section indicates distance and the vertical axis of the linear route display section indicates time.

20. The route display method of claim 15, wherein a movable body mark indicates a current position of the movable body and a reference mark indicates a position along the route according to a time schedule for the movable body.
