Operation support system

1 . An operation support system comprising:

a display mounted in a watercraft; and

a processor configured to:

cause a first view to be displayed on the display, the first view being an oblique view of an image of the vicinity of the watercraft,

cause a second view to be displayed on the display, the second view being of top view of an image of the vicinity of the watercraft of an angle different from that of the first view,

superimpose a first object simulating the watercraft and a plurality of line-shaped second objects disposed in the vicinity of the first object onto the second view, the plurality of line-shaped second objects being respectively disposed at each of divided areas on an outer edge of the first object,

superimpose a third object representing a positional relation between an obstacle in the vicinity of the watercraft and the watercraft onto the first view, the third object being an object having a first type indicating a first distance and a second type indicating a second distance which is shorter than the first distance,

cause a type of display at least at the time of displaying the plurality of line-shaped second objects to be different depending on whether the positional relation satisfies predetermined conditions or the positional relation does not satisfy the predetermined conditions,

determine whether each of the each of divided areas satisfies the predetermined conditions,

superimpose the plurality of line-shaped second objects of the second type, onto the second view, in a case in which a first condition is satisfied, the first condition being a condition where a relative distance between the watercraft and the obstacle is the second distance, and

superimpose the plurality of line-shaped second objects of the first type, onto the second view, in a case in which the first condition is not satisfied.

2 . The operation support system according to claim 1 ,

wherein the relative distance between the watercraft and the obstacle being a predetermined distance or less is included in the predetermined conditions, and

wherein the processor further configured to perform a more highlighted display of the plurality of line-shaped second objects, in a case in which the relative distance is the predetermined distance or less than in a case in which the relative distance exceeds the predetermined distance.

3 . The operation support system according to claim 1 ,

wherein a reference distance, which is a distance based on a speed of the watercraft, being a predetermined distance or less is included in the predetermined condition, and

wherein the processor further configured to perform a more highlighted display of the plurality of line-shaped second objects, in a case in which the reference distance is the predetermined distance or less than in a case in which the reference distance exceeds the predetermined distance.

4 . The operation support system according to claim 1 ,

wherein a collision prediction time between the watercraft and the obstacle being a predetermined time or less is included in the predetermined condition, and

wherein the processor further configured to perform a more highlighted display of the plurality of line-shaped second objects, in a case in which the collision prediction time is the predetermined time or less than in a case in which the collision prediction time exceeds the predetermined time.

5 . The operation support system according to claim 1 ,

wherein the first predetermined condition and a second predetermined condition that is more unlikely to be satisfied than the first predetermined condition are included in the predetermined conditions, and

wherein the processor further configured to perform a more highlighted display of the plurality of line-shaped second objects, in a case in which the positional relation satisfies the second predetermined condition than in a case in which the positional relation satisfies the first predetermined condition.

6 . The operation support system according to claim 1 , wherein the processor further configured to cause a line-shaped second object of the plurality of line-shaped second objects to be displayed on at least one of:

a lateral side of the first object,

in front of the first object, or

behind the first object.

7 . The operation support system according to claim 6 , wherein a left side and a right side are included in the lateral side.

8 . The operation support system according to claim 1 , wherein the first view acquired by imaging a side in front of the watercraft, the first view acquired by imaging a side to the rear of the watercraft, and the first view acquired by imaging a lateral side of the watercraft are included in the first view.

9 . The operation support system according to claim 1 , wherein the processor further configured to cause the display to display the first view in which a direction, in which the obstacle of which the positional relation with the watercraft satisfies the predetermined condition is present, is imaged among a plurality of the first views.

10 . The operation support system according to claim 1 , wherein the processor further configured to superimpose a fourth object with a circular shape representing a rudder angle of a propeller of the watercraft onto the second view and cause the first object and the second object to be displayed inside the fourth object.

11 . The operation support system according to claim 1 , wherein, in a case in which the positional relation satisfies the predetermined condition, the processor further configured to change a color of a line-shaped second object of the plurality of line-shaped second objects to a predetermined color corresponding to the predetermined condition.

12 . The operation support system according to claim 1 , wherein, in a case in which the positional relation satisfies the predetermined condition, the processor further configured to change a line of a line-shaped second object of the plurality of line-shaped second objects to a predetermined line corresponding to the predetermined condition.
