Abstract

Claims (66)

1. A monitoring system comprising:

a plurality of monitoring cameras that capture images; and

a management device that is connected to the plurality of monitoring cameras,

wherein the management device transmits first feature information relevant to a first person to one or more first monitoring cameras of the plurality of monitoring cameras,

wherein each of the first monitoring cameras performs a first check with respect to a first image, which is captured by the first monitoring cameras, using the received first feature information, and transmits a first check result to the management device,

wherein the management device transmits time information based on time, in which the first image including the first person is captured, to second monitoring cameras, which capture the first image relevant to the time information, among the first monitoring cameras based on the first check result,

wherein each of the second monitoring cameras performs a second check with respect to a second image, which is captured by the second monitoring cameras, using the received time information, and transmits a second check result to the management device,

wherein the management device specifies a second person based on the second check result, and

wherein the management device displays a number of times of appearances for each person who appears in the second image on a display, and specifies the second person based on the number of times of the appearances.

2. The monitoring system of claim 1 ,

wherein the management device transmits second feature information relevant to the specified second person to one or more third monitoring cameras including the first monitoring cameras, and

wherein each of the third monitoring cameras performs a third check with respect to a third image, which is captured by the third monitoring cameras, using the received second feature information, and transmits a third check result to the management device.

3. The monitoring system of claim 2 ,

wherein each of the first monitoring cameras performs the first check of detecting a feature quantity of the first person from the first image and checking the first feature information and the feature quantity of the first person,

wherein each of the second monitoring cameras performs the second check of checking the time information and time in which the second image where the feature quantity of the first person is detected is captured, and

wherein each of the third monitoring cameras performs the third check of detecting the feature quantity of the second person from the third image and checking the second feature information and the feature quantity of the second person.

4. The monitoring system of claim 1 ,

wherein the management device displays a location of each of the first monitoring cameras, which capture the first image including the first person who coincides with the first feature information, on a display based on the first check result.

5. The monitoring system of claim 4 ,

wherein the management device displays the location of each of the first monitoring cameras, which capture the first person who coincides with the first feature information, for each capturing time in which the first image is captured.

6. The monitoring system of claim 2 ,

wherein the management device displays a location of each of the third monitoring cameras, which capture the second person who coincides with the second feature information, on a display based on the third check result.

7. The monitoring system of claim 6 ,

wherein one or more the monitoring cameras are installed in each of a plurality of areas, and

wherein the management device displays the location of each of the third monitoring cameras, which capture the second person who coincides with the second feature information, for each area.

8. The monitoring system of claim 4 ,

wherein the first check result includes at least one of the location of each of the first monitoring cameras, a thumbnail image of the first image, and information of time in which the first image is captured, and

wherein, in a case where the location of each of the first monitoring cameras is maldistributed in a first area, the management device displays the first check result acquired by each of the first monitoring cameras installed in the first area.

9. The monitoring system of claim 6 ,

wherein the third check result includes at least one of the location of each of the third monitoring cameras, a thumbnail image of the third image, and information of time in which the third image is captured, and

wherein, in a case where the location of each of the third monitoring cameras is maldistributed in a second area, the management device displays the third check result acquired by each of the third monitoring cameras installed in the second area.

10. The monitoring system of claim 2 ,

wherein the monitoring cameras are installed in each of a plurality of areas, and

wherein an area in which the third monitoring cameras are installed is wider than an area in which the first monitoring cameras are installed.

11. A monitoring camera, which is connected to a management device and captures an image, comprising:

an image sensor;

a processor; and

a communication device,

wherein the image sensor captures an image of a first person,

wherein the processor detects a feature quantity of the first person from the image,

wherein the communication device receives first feature information relevant to the first person from the management device,

wherein the processor performs a first check of checking the first feature information and the feature quantity of the first person,

wherein the communication device transmits a first check result to the management device,

wherein the processor performs a second check of checking time information and feature quantity of a second person, and

wherein the communication device transmits a second check result to the management device

wherein the management device specifies the second person based on the second check result displays a number of times of appearances for each person appearing in a second image on a display, and specifies the second person based on the number of times of the appearances.

12. The monitoring camera of claim 11 ,

wherein the processor detects the feature quantity of the second person from the image, and

wherein the communication device receives the time information based on time in which the image including the first person is captured.

13. A management device, which is connected to monitoring cameras, comprising:

a processor; and

a communication device,

wherein the communication device

transmits first feature information relevant to a first person to one or more first monitoring cameras,

receives a first check result using the first feature information from each of the first monitoring cameras,

transmits time information based on time, in which a first image including the first person is captured, to second monitoring cameras, which capture the first image including the first person, among the first monitoring cameras based on the first check result,

receives a second check result from the second monitoring cameras using the time information,

wherein the processor specifies a second person based on the second check result, and

wherein the processor displays a number of times of appearances for each person who appears in a second image on a display, and specifies the second person based on the number of times of the appearances.

14. A method, comprising:

transmitting, from a management device to first monitoring cameras of a plurality of monitoring cameras coupled to the management device, first feature information relevant to a first person;

performing, by the first monitoring cameras, a first check with respect to a first image, which is captured by the first monitoring cameras, using the received first feature information, and transmitting a first check result to the management device;

transmitting, by the management device, time information based on time, in which the first image including the first person is captured, to second monitoring cameras of the plurality of monitoring cameras, which capture the first image relevant to the time information, among the first monitoring cameras based on the first check result;

performing, by the second monitoring cameras, a second check with respect to a second image, which is captured by the second monitoring cameras, using the time information, and transmitting a second check result to the management device;

specifying, by the management device, a second person based on the second check result; and

displaying, by the management device, a number of times of appearances for each person who appears in the second image on a display, and specifying the second person based on the number of times of the appearances.
