Abstract

An information processing apparatus ( 10 ) includes a time and space information acquisition unit ( 110 ) that acquires high-risk time and space information indicating a spatial region with an increased possibility of an accident occurring or of a crime being committed and a corresponding time slot, a possible surveillance target acquisition unit ( 120 ) that identifies a video to be analyzed from among a plurality of videos generated by capturing an image of each of a plurality of places, on the basis of the high-risk time and space information, and analyzes the identified video to acquire information of a possible surveillance target, and a target time and space identification unit ( 130 ) that identifies at least one of a spatial region where surveillance is to be conducted which is at least a portion of the spatial region or a time slot when surveillance is to be conducted, from among the spatial region and the time slot indicated by the high-risk time and space information, on the basis of the information of the possible surveillance target.

First claim

The invention claimed is:

1. An information processing apparatus analyzing at least one video captured by at least one camera, the information processing apparatus comprising:
at least one memory storing instructions; and
at least one processor configured to execute the instructions to:
acquire high-risk time and space information indicating a spatial region with an increased possibility of an accident occurring or of a crime being committed and at least one of a corresponding with time slot and a corresponding date;
identify, from among the spatial region and the time slot indicated by the high-risk time and space information, a spatial region where surveillance is to be conducted which is at least a portion of the spatial region and a time slot when surveillance is to be conducted, on the basis of the video;
identify a past video in the spatial region and time slot indicated by high-risk time and space information as an analysis target, analyze the analysis target, and acquire information on a possible surveillance target; and
regulate, in accordance with a number of pieces of information on the possible surveillance target, at least one of the priority of a place where a surveillance is to be conducted and a time when surveillance is to be conducted.

2. The information processing apparatus according to claim 1 , wherein the processor is further configured to:
acquire information of a possible victim of an accident or a crime; and
adjust at least one of the spatial region where surveillance is to be conducted or the time slot when surveillance is to be conducted using the information of the possible victim.

3. The information processing apparatus according to claim 1 , wherein the processor is further configured to:
acquire environmental information of a region included in the video, on the basis of the identified video or information for identifying a place of the video; and
adjust at least one of the spatial region where surveillance is to be conducted or the time slot when surveillance is to be conducted using the environmental information.

4. The information processing apparatus according to claim 1 , wherein the processor is further configured to:
accept an input of a result of surveillance according to at least one of the spatial region where surveillance is to be conducted or the time slot when surveillance is to be conducted, and
store the input result in a database.

5. An information processing method performed by a computer analyzing at least one video captured by at least one camera, the information processing method comprising:
acquiring high-risk time and space information indicating a spatial region with an increased possibility of an accident occurring or of a crime being committed and at least one of a corresponding with time slot and a corresponding date;
identifying, from among the spatial region and the time slot indicated by the high-risk time and space information, a spatial region where surveillance is to be conducted which is at least a portion of the spatial region and a time slot when surveillance is to be conducted, on the basis of the video;
identifying a past video in the spatial region and time slot indicated by high-risk time and space information as an analysis target, analyzing the analysis target, and acquiring information on a possible surveillance target; and
regulating, in accordance with a number of pieces of information on the possible surveillance target, at least one of the priority of a place where a surveillance is to be conducted and a time when surveillance is to be conducted.

6. The information processing method according to claim 5 , further comprising:
acquiring information of a possible victim of an accident or a crime; and
adjusting at least one of the spatial region where surveillance is to be conducted or the time slot when surveillance is to be conducted using the information of the possible victim.

7. The information processing method according to claim 5 , further comprising:
acquiring environmental information of a region included in the video, on the basis of the identified video or information for identifying a place of the video; and
adjusting at least one of the spatial region where surveillance is to be conducted or the time slot when surveillance is to be conducted using the environmental information.

8. The information processing method according to claim 5 , further comprising:
accepting an input of a result of surveillance according to at least one of the spatial region where surveillance is to be conducted or the time slot when surveillance is to be conducted, and
storing the input result in a database.

9. A non-transitory computer-readable medium storing a program for causing a computer analyzing at least one video captured by at least one camera to perform operations, the operations comprising:
at least one memory storing instructions; and
at least one processor configured to execute the instructions to:
acquiring high-risk time and space information indicating a spatial region with an increased possibility of an accident occurring or of a crime being committed and at least one of a corresponding with time slot and a corresponding date;
identifying, from among the spatial region and the time slot indicated by the high-risk time and space information, a spatial region where surveillance is to be conducted which is at least a portion of the spatial region and a time slot when surveillance is to be conducted, on the basis of the video;
identifying a past video in the spatial region and time slot indicated by high-risk time and space information as an analysis target, analyzing the analysis target, and acquiring information on a possible surveillance target; and
regulating, in accordance with a number of pieces of information on the possible surveillance target, at least one of the priority of a place where a surveillance is to be conducted and a time when surveillance is to be conducted.

10. The non-transitory computer-readable medium according to claim 9 , wherein the operations further comprise:
acquiring information of a possible victim of an accident or a crime; and
adjusting at least one of the spatial region where surveillance is to be conducted or the time slot when surveillance is to be conducted using the information of the possible victim.

11. The non-transitory computer-readable medium according to claim 9 , wherein the operations further comprise:
acquiring environmental information of a region included in the video, on the basis of the identified video or information for identifying a place of the video; and
adjusting at least one of the spatial region where surveillance is to be conducted or the time slot when surveillance is to be conducted using the environmental information.

12. The non-transitory computer-readable medium according to claim 9 , wherein the operations further comprise:
accepting an input of a result of surveillance according to at least one of the spatial region where surveillance is to be conducted or the time slot when surveillance is to be conducted, and
storing the input result in a database.
