Abstract

A system for monitoring event related data including a sensor data analyzer, an event analyzer and an actuator is disclosed. The sensor data analyzer detects events based on sensor data, the event analyzer couples to the sensor data analyzer and estimates the size of the detected entire events based on event related data of the detected events from the sensor data analyzer, and the actuator couples to the sensor data analyzer and the event analyzer and actuates a predetermined device based on the estimated size of the detected entire events.

Claims (44)

1. A control system comprising:

at least one memory storing instructions; and

at least one processor coupled to the at least one memory, the at least one processor configured to execute the instructions to:

detect a first event and a second event that occurred in a surveillance area by a sensing device; and

control a first size of an imaging range of a camera to a second size of the imaging range of the camera in the surveillance area by zooming-out based on detecting the second event after the first event, the second size of the image ranging camera including areas of the first event and the second event.

2. The control system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to control the imaging range based on a type of a sound event.

3. The control system according to claim 1 , wherein the processor is further configured to:

detect an abnormal odor as at least one of the first event and the second event based on the sensor data provided by an odor sensor; and

set the imaging range to a range depending on a location of the odor sensor.

4. The control system according to claim 1 , wherein the processor is further configured to:

detect an unusual crowd as at least one of the first event and the second event based on the sensor data provided by an infrared sensor; and

set the imaging range to a range depending on a location of the infrared sensor.

5. The control system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:

estimate an angle based on the first event and the second event, and

control the imaging range of the camera based on the angle.

6. A control system according to claim 1 , wherein the surveillance area is larger than the first size and the second size.

7. A control method comprising:

detecting a first event and a second event that occurred in a surveillance area by a sensing device; and

controlling a first size of an imaging range of a camera to a second size of the imaging range of the camera in the surveillance area by zooming-out based on detecting the second event after the first event, the second size of the imaging range of the camera including areas of the first event and the second event.

8. The control method according to claim 7 , wherein the controlling includes controlling the imaging range based on a type of a sound event.

9. The control method according to claim 7 , further comprising:

detecting an abnormal odor as at least one of the first event and the second event based on the sensor data provided by an odor sensor; and

setting the imaging range to a range depending on a location of the odor sensor.

10. The control method according to claim 7 , further comprising:

detecting an unusual crowd as at least one of the first event and the second event based on the sensor data provided by an infrared sensor; and

setting the imaging range to a range depending on a location of the infrared sensor.

11. A control method according to claim 7 , wherein the surveillance area is larger than the first size and the second size.

12. A non-transitory computer readable storage medium storing a program causing a computer to execute processing of:

detecting a first event and a second event that occurred in a surveillance area by a sensing device; and

controlling a first size of an imaging range of a camera to a second size of the imaging range of the camera in the surveillance area by zooming-out based on detecting the second event after the first event, the second size of the imaging range of the camera including areas of the first event and the second event.

13. The storage medium according to claim 12 , wherein the controlling includes controlling the imaging range based on a type of a sound event.

14. The storage medium according to claim 12 , wherein the program further causing a computer to execute processing of:

detecting an abnormal odor as at least one of the first event and the second event based on the sensor data provided by an odor sensor; and

setting the imaging range to a range depending on a location of the odor sensor.

15. The storage medium according to claim 12 , wherein the program further causing a computer to execute processing of:

detecting an unusual crowd as at least one of the first event and the second event based on the sensor data provided by an infrared sensor; and

setting the imaging range to a range depending on a location of the infrared sensor.

16. A storage medium according to claim 12 , wherein the surveillance area is larger than the first size and the second size.

17. A control system comprising:

at least one memory storing instructions; and

at least one processor coupled to the at least one memory, the at least one processor configured to execute the instructions to:

detect a first target and a second target from occurrences in a surveillance area by a sensing device; and

control a first size of an imaging range of a camera to a second size of the imaging range of the camera in the surveillance area by zooming-out based on detecting the second event after the first event, the second size of the imaging range of the camera including areas of the first target and the second target.

18. A control system according to claim 17 , wherein the surveillance area is larger than the first size and the second size.
