Apparatus for presenting result of recognizing recognition target
There are provided an apparatus, a method, and an autonomous moving body which allow a recognition target to be notified with certainty that the recognition target is recognized by an autonomous moving body. A recognition result presenting apparatus according to an embodiment of the present disclosure detects a recognition target (person) present within a predetermined range from an automatic driving vehicle and presents, to the detected recognition target (person), the result of recognition indicating that the automatic driving vehicle recognizes the recognition target (person).
1. A system comprising:
a light emitter mounted on an autonomous moving body;
a processor; and
a memory storing thereon a computer program, which when executed by the processor, causes the processor to perform operations including:
acquiring positional information of a recognition target present within a predetermined range around the autonomous moving body, the positional information having been generated by detecting the recognition target via a sensor mounted on the autonomous moving body; and
emitting, via the light emitter, a light to the detected recognition target to alert the recognition target that the autonomous moving body recognizes the recognition target after the positional information is acquired.
2. The system according to claim 1 , wherein
the light is at least partly emitted onto a ground on which the recognition target is present.
3. The system according to claim 2 , wherein
the emitted light has a predetermined pattern on the ground.
4. The system according to claim 3 , wherein
the recognition target is a person, and
the predetermined pattern includes
a first part for informing the person of being the recognition target, and
a second part for informing the person that the light is emitted from the autonomous moving body.
5. The system according to claim 4 , wherein
the second part has a linear shape extending between the autonomous moving body and the recognition target.
6. The system according to claim 1 , wherein
the light is at least partly emitted onto a ground between the light emitter and the recognition target.
7. The system according to claim 1 , wherein
the sensor includes a camera configured to capture an image of a scene within the predetermined range.
8. The system according to claim 7 , wherein
in the emitting, an image obtained from the captured image is presented to the recognition target using the light.
9. The system according to claim 8 , wherein
the presented image is an image obtained by horizontally flipping the captured image.
10. The system according to claim 8 , wherein
the light emitter is included in a display mounted on a surface of the autonomous moving body.
11. The system according to claim 1 , wherein
the operations further include
determining an attribute of the detected recognition target, and
the emitted light is different depending on the attribute of the detected recognition target.
12. The system according to claim 1 , wherein
the operations further include
determining a degree of danger to which the detected recognition target is exposed, and
the emitted light is different depending on the degree of danger.
13. The system according to claim 12 , wherein
the emitted light has a different color depending on the degree of danger.
14. The system according to claim 1 , wherein
the operations further include
outputting, via a speaker mounted on the autonomous moving body, a sound to the detected recognition target to alert the recognition target that the autonomous moving body recognizes the recognition target after the positional information is acquired.
15. The system according to claim 14 , wherein
the operations further include
determining a degree of danger to which the detected recognition target is exposed, and
the output sound is different depending on the degree of danger.
16. The system according to claim 1 , wherein
the light emitter is a laser or a light-emitting diode.
17. The system according to claim 1 , wherein
the autonomous moving body is a car, a truck, or a bus.
18. An autonomous moving body comprising:
the system according to claim 1 ; and
a controller that controls movement of the autonomous moving body in accordance with a situation of the detected recognition target.
