Abstract

In order to provide a technique capable of presenting information that is different from the image of a surveillance camera and is effective for searching for a person, this search information providing device includes, as functional units, a collation unit and an output unit. The collation unit collates a fingerprint image obtained by a fingerprint photographing device with a fingerprint image, of a search target person, given in advance. When the fingerprint image on the handrail member matches the fingerprint image of the search target person, the output unit outputs information indicating that the search target person has been detected to a predetermined reporting destination.

First claim

What is claimed is:

1. A search information providing system comprising:
a search information providing device; and
a fingerprint capturing device,
wherein the search information providing device includes:
at least one processor configured to:
collate an image of a fingerprint of a person in a captured image of a fingerprint mark of the person left on a handrail member with an image of a fingerprint of a search target person that is given in advance, the handrail member circulating in a circulation path passing through an outward part and a return part, the outward part being a part of the circulation path to assist the person while moving along with movement of a conveyance member that conveys the person by moving from an entrance toward an exit, the return part being a part of the circulation path to move in a direction from the exit toward the entrance; and
when the image of the fingerprint of the person on the handrail member matches the image of the fingerprint of the search target person, output, to a predetermined reporting destination, information indicating that the search target person has been detected,

wherein the fingerprint capturing device is configured to capture the fingerprint mark of the person left on the handrail member at the return part of the circulation path and supplies the image of the fingerprint of the person to the search information providing device,
wherein the search information providing system further includes:
an adhesion device configured to cause a luminescent agent for causing the fingerprint mark of the person in the handrail member to become luminescent to adhere to the handrail member at a part of the circulation path nearer than a part of the circulation path captured by the fingerprint capturing device;
an irradiation device configured to irradiate a part of the handrail member, the part to be captured by the fingerprint capturing device, with light that causes the luminescent agent to become luminescent; and
a removal device configured to remove the fingerprint mark of the person and the luminescent agent left on the handrail member, at a part after passing through the part of the circulation path captured by the fingerprint capturing device.

2. The search information providing system according to claim 1 , wherein the at least one processor outputs, as information indicating that the search target person has been detected, information for identifying the search target person, time information indicating captured time at which the image of the fingerprint of the person is captured, and information indicating a place of capturing.

3. The search information providing system according to claim 1 , wherein the adhesion device, the irradiation device, the fingerprint capturing device, and the removal device are accommodated in a same housing.

4. The search information providing system according to claim 1 further comprising:
a person capturing device configured to capture a person conveyed by the conveyance member, wherein
the at least one processor included in the search information providing device is further configured to:
associate the image of the fingerprint captured by the fingerprint capturing device with an image including the person which is captured by the person capturing device and has a fingerprint captured in the image by the fingerprint capturing device, and
output, to the reporting destination, the image of the person associated with the image of the fingerprint of the person matching the image of the fingerprint of the search target person, when the image of the fingerprint of the person on the handrail member matches the image of the fingerprint of the search target person.

5. A search information providing method comprising:
by a computer installed in a search information providing device, collating an image of a fingerprint of a person in a captured image of a fingerprint mark of the person left on a handrail member with an image of a fingerprint of a search target person that is given in advance, the handrail member circulating in a circulation path passing through an outward part and a return part, the outward part being a part of the circulation path to assist the person while moving along with movement of a conveyance member that conveys the person by moving from an entrance toward an exit, the return part being a part of the circulation path to move in a direction from the exit toward the entrance; and
when the image of the fingerprint of the person on the handrail member matches the image of the fingerprint of the search target person, outputting, to a predetermined reporting destination, information indicating that the search target person has been detected,
by a fingerprint capturing device, capturing the fingerprint mark of the person left on the handrail member at the return part of the circulation path and supplying the image of the fingerprint of the person to the search information providing device,
by an adhesion device, causing a luminescent agent for causing the fingerprint mark of the person in the handrail member to become luminescent to adhere to the handrail member at a part of the circulation path nearer than a part of the circulation path captured by the fingerprint capturing device;
by an irrigation device, irradiating a part of the handrail member, the part to be captured by the fingerprint capturing device, with light that causes the luminescent agent to become luminescent; and
by a removal device, removing the fingerprint mark of the person and the luminescent agent left on the handrail member, at a part after passing through the part of the circulation path captured by the fingerprint capturing device.
