Abstract

A guidance processing apparatus ( 100 ) includes an information acquisition unit ( 101 ) that acquires a plurality of different pieces of guidance information on the basis of states of a plurality of people within one or more images, and a control unit ( 102 ) that performs control of a plurality of target devices present in different spaces or time division control of a target device so as to set a plurality of different states corresponding to the plurality of pieces of guidance information.

First claim

The invention claimed is:

1. A guidance processing system comprising:
at least one memory storing instructions; and
at least one processor configured to execute the instructions to perform:
analyzing surveillance images to acquire a state of a crowd in a target area;
detecting a change in the state of the crowd in the target area;
detecting an abnormal state of the crowd on the basis of the detected change in the state of the crowd;
detecting a degree of abnormality of the crowd on the basis of the number of people causing the change of the state of the crowd, the state including at least one of a state where the people turn around and a state where the people start running;
comparing the degree of abnormality of the crowd in the target area with a degree of abnormality of a crowd in another area;
in response to determining that the degree of abnormality of the crowd in the target area severely differs from the degree of abnormality of the crowd in the another area,
generating guidance information corresponding to the target area; and
outputting the guidance information on a display device.

2. The guidance processing system according to claim 1 ,
wherein the state of the crowd is a degree of crowdedness and the abnormal state of the crowd is a degree of dissatisfaction of the crowd.

3. The guidance processing system according to claim 1 ,
wherein the at least one processor is configured to execute the instructions to perform generating the guidance information using environment condition information indicating conditions of an environment.

4. The guidance processing system according to claim 1 , wherein the guidance information includes a predicted crowdedness in the target area.

5. The guidance processing system according to claim 1 ,
wherein the at least one processor is configured to execute the instructions to perform:
acquiring the degree of crowdedness in a first target area and acquiring a flow rate in a second target area; and
calculating a predicted crowdedness in the first target area at a point in time in the future based on the flow rate.

6. The guidance processing system according to claim 1 ,
wherein the at least one processor is configured to execute the instructions to perform:
determining a degree of influence of a peripheral area on the degree of crowdedness in the target area; and
generating the guidance information for suppressing an increase in a number of people moving from the peripheral area with a high degree of influence on the target area to the target area.

7. A guidance processing method executed by a computer and comprising:
analyzing surveillance images to acquire a state of a crowd in a target area;
detecting a change in the state of the crowd in the target area;
detecting an abnormal state of the crowd on the basis of the detected change in the state of the crowd;
detecting a degree of abnormality of the crowd on the basis of the number of people causing the change of the state of the crowd, the state including at least one of a state where the people turn around and a state where the people start running;
comparing the degree of abnormality of the crowd in the target area with a degree of abnormality of a crowd in another area;
in response to determining that the degree of abnormality of the crowd in the target area severely differs from the degree of abnormality of the crowd in the another area,
generating guidance information corresponding to the target area; and
outputting the guidance information on a display device.

8. The guidance processing method according to claim 7 ,
wherein the state of the crowd is a degree of crowdedness and the abnormal state of the crowd is a degree of dissatisfaction of the crowd.

9. The guidance processing method according to claim 7 , further comprising
generating the guidance information using environment condition information indicating conditions of an environment.

10. The guidance processing method according to claim 7 , wherein the guidance information includes a predicted crowdedness in the target area.

11. The guidance processing method according to claim 7 , further comprising:
acquiring the degree of crowdedness in a first target area and acquiring a flow rate in a second target area; and
calculating a predicted crowdedness in the first target area at a point in time in the future based on the flow rate.

12. The guidance processing method according to claim 7 , further comprising:
determining a degree of influence of a peripheral area on the degree of crowdedness in the target area; and
generating the guidance information for suppressing an increase in a number of people moving from the peripheral area with a high degree of influence on the target area to the target area.

13. A non-transitory computer-readable medium storing a program for causing a computer to perform operations comprising:
analyzing surveillance images to acquire a state of a crowd in a target area;
detecting a change in the state of the crowd in the target area;
detecting an abnormal state of the crowd on the basis of the detected change in the state of the crowd;
detecting a degree of abnormality of the crowd on the basis of the number of people causing the change of the state of the crowd, the state including at least one of a state where the people turn around and a state where the people start running;
comparing the degree of abnormality of the crowd in the target area with a degree of abnormality of a crowd in another area;
in response to determining that the degree of abnormality of the crowd in the target area severely differs from the degree of abnormality of the crowd in the another area,
generating guidance information corresponding to the target area; and
outputting the guidance information on a display device.

14. The non-transitory computer-readable medium according to claim 13 ,
wherein the state of the crowd is a degree of crowdedness and the abnormal state of the crowd is a degree of dissatisfaction of the crowd.

15. The non-transitory computer-readable medium according to claim 13 ,
wherein the operations further comprise generating the guidance information using environment condition information indicating conditions of an environment.

16. The non-transitory computer-readable medium according to claim 13 , wherein the guidance information includes a predicted crowdedness in the target area.

17. The non-transitory computer-readable medium according to claim 13 ,
wherein the operations further comprise:
acquiring the degree of crowdedness in a first target area and acquiring a flow rate in a second target area; and
calculating a predicted crowdedness in the first target area at a point in time in the future based on the flow rate.
