Abstract

A moving body system includes an imaging device attachable to a moving body, a visual line direction changing mechanism configured to change a visual line direction of the imaging device and a control unit configured to change the visual line direction of the imaging device in accordance with changing of a movement direction of the moving body.

Claims

1. A moving body system comprising:

an imaging device attachable to a moving body;

a visual line direction changing mechanism configured to change a visual line direction of the imaging device; and

a control unit configured to change the visual line direction of the imaging device in accordance with changing of a movement direction of the moving body.

2. The moving body system as claimed in claim 1, wherein the control unit is configured to control the visual line direction of the imaging device such that an angle made by the visual line direction of the imaging device and the movement direction of the moving body is changed in accordance with a changing amount of the movement direction of the moving body.

3. The moving body system as claimed in claim 1, wherein the control unit is configured to control the visual line direction of the imaging device based on at least one of information of a steering operation angle of the moving body, information of a steering operation speed of the moving body, and information of an angle of inclination of a wheel of the moving body.

4. The moving body system as claimed in claim 1, wherein the control unit is configured to control the visual line direction of the imaging device such that the larger a changing amount of the movement direction of the moving body becomes, the larger an angle made by the visual line direction of the imaging device and the movement direction of the moving body becomes.

5. The moving body system as claimed in claim 1, wherein the moving body is a vehicle.

6. The moving body system as claimed in claim 5, wherein the control unit is configured to control the visual line direction of the imaging device such that the visual line direction of the imaging device is angled with respect to the movement direction of the vehicle inside of a turning direction of the vehicle.

7. The moving body system as claimed in claim 5, wherein the control unit is configured to detect a changing amount of the movement direction of the moving body based on at least one of a steering operation angle of the vehicle, an angle of inclination of a wheel of the vehicle, and a changing of images captured by the imaging device.

8. The moving body system as claimed in claim 1, wherein the moving body is a flight body.

9. The moving body system as claimed in claim 8,

wherein the flight body is configured to be operated by a control stick, and

wherein the control unit is configured to detect the changing of the movement direction of the flight body based on a changing of a control signal of the control stick in order to control the visual line direction of the imaging device.

10. The moving body system as claimed in claim 8,

wherein the flight body is configured to be remotely operated by a radio control device, and

wherein the control unit is configured to control the visual line direction of the imaging device based on at least one of a control signal of the radio control unit and image information captured by the imaging device.

11. The moving body system as claimed in claim 1, wherein the control unit is configured to change at least one of a frame rate of the imaging device and a recognition process rate of the imaging device in accordance with the changing of the movement direction of the moving body.

12. The moving body system as claimed in claim 11, wherein the control unit is configured to make at least one of the frame rate of the imaging device and the recognition process rate of the imaging device higher in accordance with the changing of the movement direction of the moving body.

13. The moving body system as claimed in claim 11, wherein the control unit is configured to return the at least one of the frame rate of the imaging device and the recognition process rate of the imaging device which is changed to its original rate in accordance with an event in which the movement direction of the moving body returns to a straight direction after the visual line direction of the imaging device has been changed.

14. The moving body system as claimed in claim 11, wherein the control unit is configured to make the frame rate of the imaging device higher in a case in which an object exists in a predetermined distance from the moving body than the frame rate of the imaging device in a case in which the object does not exist in the predetermined distance from the moving body.

15. The moving body system as claimed in claim 1, wherein the imaging device is a stereo camera.

16. A moving body system comprising:

an imaging device attachable to a moving body, the imaging device being configured to capture a predetermined area with respect to the moving body, the predetermined area being outside of the moving body;

a predetermined area changing mechanism configured to move the imaging device with respect to the moving body in order to change the predetermined area with respect to the moving body in a state in which the imaging device is attached to the moving body; and

a control unit configured to control the changing mechanism in order to change the predetermined area with respect to the moving body in accordance with changing of a movement direction of the moving body.

17. The moving body system as claimed in claim 16, wherein the control unit is configured to control the predetermined area changing mechanism in order to change the predetermined area with respect to the moving body in accordance with an operation of a movement direction changing mechanism which is configured to change the movement direction of the moving body.

18. The moving body system as claimed in claim 16, wherein in accordance with changing of the movement direction of the moving body by a first angle to one side, the control unit is configured to control the predetermined area changing mechanism in order to change the predetermined area with respect to the moving body by a second angle to the one side, the second angle being larger than the first angle.

19. The moving body system as claimed in claim 18, wherein in a case in which a changing angle of the movement direction of the moving body is less than the first angle, the control unit is configured to control the predetermined area changing mechanism in order not to change the predetermined area with respect to the moving body.
