## Abstract

A missing child prevention support system is provided and includes: a grouping part configured to recognize a group of users who are facility users entering a facility and generate user group information indicating a user group; an image acquisition part configured to acquire facility images including images of the users from imaging devices of the facility; a guide control part configured to control an operation of a movable guiding device performing guiding for the users in the facility; a guide grouping specifying part configured to specify the user group of the users for which the guiding device performs the guiding; and a missing child estimation part configured to estimate an unguided user who is a user not belonging to the user group as a potential missing child when the unguided user is shown in the facility images.

## Claims

### Claim 1

A missing child prevention support system comprising:
a grouping part, configured to recognize a group of users who are facility users entering a facility and generate a user group information indicating a user group;
an image acquisition part, configured to acquire facility images including images of the users from imaging devices of the facility;
a guide control part, configured to control an operation of a movable guiding device performing a guiding for the users in the facility;
a guide grouping specifying part, configured to specify the user group of the users for which the guiding device performs the guiding; and
a missing child estimation part, configured to estimate an unguided user who is a user not belonging to the user group as a potential missing child, when the unguided user is shown in the facility images.

### Claim 2 (depends on 1)

The missing child prevention support system according to claim 1, wherein
the imaging devices include an imaging device with which the guiding device is equipped.

### Claim 3 (depends on 1)

The missing child prevention support system according to claim 1, wherein
the grouping part is configured to generate the user group information based on talk analysis of talk voices with the users acquired from a reception device talking with the users entering the facility and talk analysis of talk voices between the guiding device and the users acquired from the guiding device.

### Claim 4 (depends on 2)

The missing child prevention support system according to claim 2, wherein
the grouping part is configured to generate the user group information based on talk analysis of talk voices with the users acquired from a reception device talking with the users entering the facility and talk analysis of talk voices between the guiding device and the users acquired from the guiding device.

### Claim 5 (depends on 1)

The missing child prevention support system according to claim 1, further comprising:
an alert operation part, configured to specify a position of the unguided user who is estimated as the potential missing child based on the facility images or positions of the imaging devices imaging the unguided user and perform an alert operation in accordance with the specified position.

### Claim 6 (depends on 2)

The missing child prevention support system according to claim 2, further comprising:
an alert operation part, configured to specify a position of the unguided user who is estimated as the potential missing child based on the facility images or positions of the imaging devices imaging the unguided user and perform an alert operation in accordance with the specified position.

### Claim 7 (depends on 3)

The missing child prevention support system according to claim 3, further comprising:
an alert operation part, configured to specify a position of the unguided user who is estimated as the potential missing child based on the facility images or positions of the imaging devices imaging the unguided user and perform an alert operation in accordance with the specified position.

### Claim 8 (depends on 4)

The missing child prevention support system according to claim 4, further comprising:
an alert operation part, configured to specify a position of the unguided user who is estimated as the potential missing child based on the facility images or positions of the imaging devices imaging the unguided user and perform an alert operation in accordance with the specified position.
