Abstract

An information processing apparatus according to the present invention includes: a display control unit that displays, on a screen, a map of a search area, a camera icon indicating a location of a surveillance camera in the map, and a person image of a search target person; an operation receiving unit that receives an operation of superimposing, on the screen, one of the person image or the camera icon on the other; and a processing request unit that requests a matching process between the person image and a surveillance video captured by the surveillance camera corresponding to the camera icon based on the operation.

First claim

What is claimed is:

1. An information processing apparatus comprising:
at least one memory storing instructions; and
at least one processor configured to execute the instructions to:
display at least a map of a search area and one camera icon on a screen, the at least one camera icon corresponding to at least one camera and indicating a location of the at least one camera on the map;
display at least one person image on the screen, the at least one person image showing at least one person;
receive an operation to superimpose one of the at least one person image or the at least one camera icon on the other;
request a first matching process based on the operation to superimpose one of the at least one person image or the at least one camera icon on the other, the first matching process matching between the at least one person image and the at least one video captured by the at least one camera;
receive an operation to superimpose a specified person image on a camera icon displayed on the screen which is different from the at least one camera icon, the specified person image showing a person who is specified from an extracted video; and
request a second matching process based on the operation to superimpose the specified person image on the camera icon displayed on the screen, the second matching process matching between the specified person image and a video captured by a camera corresponding to the camera icon.

2. The information processing apparatus according to claim 1 , wherein the at least one processor further is configured to execute the instructions to:
display the extracted video on the screen, the extracted video showing the at least one person and extracted from the at least one video.

3. The information processing apparatus according to claim 1 ,
wherein the at least one camera icon comprises a plurality of camera icons; wherein the at least one camera comprises a plurality of cameras, the plurality of the cameras corresponding to the plurality of the camera icons;
wherein the at least one video comprises a plurality of videos, each of the plurality of the videos captured by each of the plurality of the cameras; and
wherein the at least one processor further is configured to execute the instructions to:
receive an operation to superimpose collectively the at least one person image on the plurality of the camera icons; and
request third matching process based on the operation to superimpose collectively the at least one person image on the plurality of the camera icons, the third matching process matching between the at least one person image and each of the plurality of the videos.

4. The information processing apparatus according to claim 3 , wherein the at least one processor further is configured to execute the instructions to:
change the plurality of the camera icons in response to the third matching process.

5. The information processing apparatus according to claim 1 ,
wherein the at least one person comprises a plurality of persons searched by the first search process;
wherein the at least one person image comprises a plurality of person images, each of the plurality of the person images showing each of the plurality of the persons; and
wherein the at least one processor further is configured to execute the instructions to:
receive an operation to superimpose collectively the plurality of the person images on the at least one camera icon; and
request fourth matching process based on the operation to superimpose collectively the plurality of the person images on the at least one camera icon, the fourth matching process matching between each of the plurality of the person images and the at least one video.

6. The information processing apparatus according to claim 5 , wherein the at least one processor further is configured to execute the instructions to:
display an extracted video on the screen, the extracted video showing at least one person who matched by the fourth matching process.

7. The information processing apparatus according to claim 5 , wherein the at least one processor further is configured to execute the instructions to:
display an extracted video on the screen, the extracted video simultaneously showing all of persons who matched by the fourth matching process.

8. The information processing apparatus according to claim 1 , wherein the at least one processor further is configured to execute the instructions to:
determine a period for the first matching process based on a time capturing the at least one person, position information of a camera capturing the at least one person, and position information of the at least one camera, the position information of the camera being different from the position information of the at least one camera.

9. The information processing apparatus according to claim 8 ,
wherein the instructions to determine the period for the first matching process determine the period for the first matching process based on a speed of the at least one person.

10. The information processing apparatus according to claim 2 , wherein the at least one processor further is configured to execute the instructions to:
display a sign on the extracted video, the sign indicating a direction to a location located in a camera which is different from the at least one camera corresponding to the extracted video.

11. The information processing apparatus according to claim 2 , wherein the at least one processor further is configured to execute the instructions to:
display identification information on the extracted video, the identification information corresponding to a camera located in a direction in which the at least one person proceeds.

12. The information processing apparatus according to claim 1 , wherein the at least one processor further is configured to execute the instructions to:
highlight a camera icon corresponding to a camera located in a direction in which the at least one person proceeds.

13. The information processing apparatus according to claim 1 , wherein the at least one processor further is configured to execute the instructions to:
receive specified information related to at least one of clothes of the at least one person, articles to be carried by the at least one person, age of the at least one person, gender of the at least one person or gait of the at least one person;
wherein the instructions to request a first matching process based on the operation to superimpose one of the at least one person image or the at least one camera icon on the other request the first matching process based on the specified information and the at least one person image.

14. The information processing apparatus according to claim 1 ,
wherein the instructions to display at least one person image on the screen include to display a video showing the at least one person on the screen, the video captured by a camera, the camera corresponding to a camera icon displayed on the screen, the camera icon being different from the at least one camera icon; and
wherein the at least one person image is obtained from the video displayed on the screen.

15. The information processing apparatus according to claim 1 ,
wherein the instructions to display at least one person image on the screen include to display, on the screen, at least one of a still image stored or a moving image stored; and
wherein the at least one person image is obtained from the at least one of a still image or a moving image displayed on the screen.

16. The information processing apparatus according to claim 15 ,
wherein the instructions to display at least
