Abstract

The present technique relates to a mobile body and a control method by which multiple mobile bodies that are performing photographing can be inhibited from obstructing each other's photographing. The mobile body receives photographing information including information regarding a photographing range which is photographed by another mobile body. Subsequently, the mobile body controls a photographing action of a camera for performing photographing, according to the photographing information regarding the other mobile body. The present technique is applicable to, for example, a photographing system that performs aerial photographing using multiple drones, or the like.

First claim

1 . A mobile body comprising:
a communication section that receives photographing information including information regarding a photographing range that is photographed by another mobile body; and a photographing action control section that controls a photographing action of a camera according to the photographing information regarding the other mobile body received by the communication section.

2 . The mobile body according to claim 1 , further comprising:
a cost information deriving section that generates the photographing information including an obstruction cost and range information, the obstruction cost being set for a photographing range of the mobile body and representing a likelihood that the other mobile body obstructs photographing being performed by the mobile body, the range information indicating a cost application range to which the obstruction cost is applied in the photographing range.

3 . The mobile body according to claim 2 , wherein
the cost information deriving section generates the photographing information including an obstruction cost and range information, the obstruction cost being set for a predicted photographing range that is predicted to become the photographing range of the mobile body, the range information indicating a cost application range to which the obstruction cost is applied in the predicted photographing range.

4 . The mobile body according to claim 3 , wherein
the photographing action control section controls the photographing action according to a combined cost that is obtained by combining the obstruction cost included in the photographing information regarding the other mobile body.

5 . The mobile body according to claim 4 , wherein
the photographing action control section causes a movement of the mobile body to a corrected photographing position that is obtained through a correction according to the combined cost.

6 . The mobile body according to claim 5 , wherein
the photographing action control section causes a movement of the mobile body to the corrected photographing position, along a movement path that is set according to the combined cost.

7 . The mobile body according to claim 3 , wherein
the cost information deriving section sets the predicted photographing range according to a photographing target of the camera.

8 . The mobile body according to claim 3 , wherein
the cost information deriving section sets the obstruction cost according to a photographing target of the camera.

9 . The mobile body according to claim 3 , wherein
the cost information deriving section sets the obstruction cost according to an attention region that is set in the photographing range of the mobile body.

10 . The mobile body according to claim 3 , wherein
the cost information deriving section sets the obstruction cost according to a focal distance of the camera.

11 . The mobile body according to claim 3 , wherein
the cost information deriving section sets, as the predicted photographing range, a range that becomes the photographing range when a subject located outside the photographing range of the mobile body is photographed.

12 . The mobile body according to claim 3 , wherein
the cost information deriving section sets a photographing prohibition position at which the other mobile body's photographing is prohibited, and generates the photographing information including the photographing prohibition position.

13 . The mobile body according to claim 12 , wherein
the photographing action control section inhibits photographing of the photographing prohibition position included in the photographing information regarding the other mobile body.

14 . The mobile body according to claim 3 , wherein
the cost information deriving section sets the obstruction cost according to a shielded range that includes a dead angle to the camera.

15 . The mobile body according to claim 1 , wherein
the mobile body includes a drone.

16 . A control method comprising:
by a mobile body, receiving photographing information including information regarding a photographing range that is photographed by another mobile body; and controlling a photographing action of a camera according to the photographing information regarding the other mobile body.
