Abstract

An autonomous mobile system according to the present embodiment is an autonomous mobile system that autonomously moves in a facility provided with a corner between aisles. When the autonomous mobile system turns at the corner, the autonomous mobile system calculates a magnitude of a corner radius of turning in a traveling path based on an obstacle captured in image data of a camera that captures an image of an exit of the corner.

Claims (38)

1. An autonomous mobile system that autonomously moves in a facility provided with a corner in an aisle, wherein when the autonomous mobile system turns at the corner, the autonomous mobile system calculates a magnitude of a corner radius of turning in a traveling path based on an obstacle captured in image data of a camera that captures an image of an exit of the corner, and turns at the corner with the calculated corner radius,

wherein the corner is configured by a first aisle extending in one direction and a second aisle extending in another direction intersecting the one direction, and

wherein, when the autonomous mobile system is not able to acquire the image data, the autonomous mobile system calculates the corner radius that provides the traveling path along outer edges of the first aisle and the second aisle on an outer side at the corner, and the autonomous mobile system travels in the traveling path along the outer edges.

2. The autonomous mobile system according to claim 1 , wherein the autonomous mobile system calculates the magnitude of the corner radius in accordance with a ratio of the obstacle occupying a space in the image data.

3. The autonomous mobile system according to claim 1 , wherein the autonomous mobile system calculates the magnitude of the corner radius in accordance with a type of the obstacle in the image data.

4. The autonomous mobile system according to claim 1 ,

wherein the autonomous mobile system calculates the corner radius that provides the traveling path along the outer edges of the first aisle and the second aisle on the outer side at the corner, depending on a type of the obstacle in the image data.

5. The autonomous mobile system according to claim 4 , wherein the autonomous mobile system stands by near a connection point between the outer edge of the first aisle on the outer side and the outer edge of the second aisle on the outer side.

6. The autonomous mobile system according to claim 1 , wherein the autonomous mobile system stands by near a connection point between the outer edge of the first aisle on the outer side and the outer edge of the second aisle on the outer side.

7. The autonomous mobile system according to claim 1 , wherein the autonomous mobile system calculates a moving speed based on the obstacle captured in the image data, and turns at the corner at the calculated moving speed.

8. An autonomous mobile system, comprising:

an autonomous mobile device that autonomously moves in a facility provided with a corner in an aisle;

a facility camera that is fixed in the facility and captures an image of an exit of the corner to generate image data; and

a server device that transmits and receives traveling information to and from the autonomous mobile device and acquires the image data from the facility camera, wherein:

when the autonomous mobile device turns at the corner, the server device calculates a magnitude of a corner radius of turning in a traveling path of the autonomous mobile device based on an obstacle captured in image data of the camera that captures the image of the exit of the corner; and

the autonomous mobile device turns at the corner with the calculated corner radius,

wherein the corner is configured by a first aisle extending in one direction and a second aisle extending in another direction intersecting the one direction;

wherein when the server device is not able to acquire the image data, the server device calculates the corner radius that provides the traveling path along outer edges of the first aisle and the second aisle on an outer side at the corner; and

wherein the server device causes the autonomous mobile device to travel in the traveling path along the outer edges.

9. The autonomous mobile system according to claim 8 , wherein the server device calculates the magnitude of the corner radius in accordance with a ratio of the obstacle occupying a space in the image data.

10. The autonomous mobile system according to claim 8 , wherein the server device calculates the magnitude of the corner radius in accordance with a type of the obstacle in the image data.

11. The autonomous mobile system according to claim 8 , wherein the server device calculates the corner radius that provides the traveling path along the outer edges of the first aisle and the second aisle on the outer side at the corner, depending on a type of the obstacle in the image data.

12. The autonomous mobile system according to claim 11 , wherein the autonomous mobile device stands by near a connection point between the outer edge of the first aisle on the outer side and the outer edge of the second aisle on the outer side.

13. The autonomous mobile system according to claim 8 , wherein the autonomous mobile device stands by near a connection point between the outer edge of the first aisle on the outer side and the outer edge of the second aisle on the outer side.

14. The autonomous mobile system according to claim 8 , wherein:

the server device calculates a moving speed of the autonomous mobile device based on the obstacle captured in the image data; and

the autonomous mobile device turns at the corner at the calculated moving speed.

15. An autonomous mobile method for an autonomous mobile device that autonomously moves in a facility provided with a corner in an aisle includes:

a step of calculating, when the autonomous mobile device turns at the corner, a magnitude of a corner radius of turning in a traveling path of the autonomous mobile device based on an obstacle captured in image data of a camera that captures an image of an exit of the corner; and

a step of causing the autonomous mobile device to turn at the corner with the calculated corner radius,

wherein the corner is configured by a first aisle extending in one direction and a second aisle extending in another direction intersecting the one direction, and

wherein when the image data is not able to be acquired, the corner radius is calculated to provide the traveling path along outer edges of the first aisle and the second aisle on an outer side at the corner, and the autonomous mobile device is caused to travel in the traveling path along the outer edges.

16. A non-transitory storage medium that stores an autonomous mobile program for an autonomous mobile device that autonomously moves in a facility provided with a corner in an aisle, the autonomous mobile program causing a computer to:

calculate, when the autonomous mobile device turns at the corner, a magnitude of a corner radius of turning in a traveling path of the autonomous mobile device based on an obstacle captured in image data of a camera that captures an image of an exit of the corner; and

cause the autonomous mobile device to turn at the corner with the calculated corner radius,

wherein the corner is configured by a first aisle extending in one direction and a second aisle extending in another direction intersecting the one direction;

wherein when the image data is not able to be acquired, the corner radius is calculated to provide the traveling path along outer edges of the first aisle and the second aisle on an outer side at the corner; and

wherein the autonomous mobile device is caused to travel in the traveling path along the outer edges.
