Abstract

According to one embodiment, a monitoring system includes a monitoring terminal and a server. The monitoring terminal includes a detector, a tracking unit, a first selector, and a transmitter. The server includes a receiver, a second selector, a collation unit, and an output unit. The receiver receives a first best shot images from the monitoring terminal. The second selector performs second selection processing, as part of a predetermined selection processing other than a first selection processing, of selecting a second best shot image suitable for collation with a predetermined image from among the first best shot images. The collation unit performs collation processing of collating the second best shot image with the predetermined image. The output unit outputs a result of the collation processing.

First claim

What is claimed is:

1 . A monitoring system comprising:
a monitoring terminal that comprises:
a detector configured to detect images of an object that are object images from frames constituting a moving image obtained by imaging a predetermined position with an imaging unit;
a tracking unit configured to track the object images of the same object across the frames;
a first selector configured to perform first selection processing, as part of predetermined selection processing, of selecting first best shot images suitable for collation with a predetermined image from among the object images of the same object; and
a transmitter configured to transmit the first best shot images to a server; and
the server that comprises:
a receiver configured to receive the first best shot images from the monitoring terminal;
a second selector configured to perform second selection processing, as part of the predetermined selection processing other than the first selection processing, of selecting a second best shot image suitable for collation with the predetermined image from among the first best shot images;
a collation unit configured to perform collation processing of collating the second best shot image with the predetermined image; and
an output unit configured to output a result of the collation processing.

2 . The system according to claim 1 , wherein
the collation unit calculates similarity between the second best shot image and the predetermined image; the output unit outputs the similarity as a result of the collation processing; and in the second selection processing, a best shot degree as a degree of the similarity with respect to the first best shot images based on a selection result of the second best shot image and a calculation result of the similarity, and an image the best shot degree of which is equal to or larger than a predetermined value is selected as the second best shot image from among the first best shot images.

3 . The system according to claim 1 , wherein
the monitoring terminal further comprises a reading unit configured to read an image from a recording medium carried by a person passing through the predetermined position, the transmitter transmits the first best shot images and the read image to the server, and the collation unit collates the read image as the predetermined image with the second best shot image.

4 . The system according to claim 2 , wherein the server further comprises a learning unit configured to learn parameters of the first selection processing with which the best shot degree of the first best shot images is increased based on a collation result between the second best shot image and the predetermined image, and transmit the parameters to the monitoring terminal.

5 . The system according to claim 4 , wherein the first selector performs the first selection processing in accordance with the parameters received from the server.
