Monitoring system, monitoring device and method, recording medium, and program
First Claim
1. A monitoring system, comprising:
- an image pickup apparatus for imaging monitoring region to output a monitor image;
face detection means for detecting an image of the face of an approaching individual, who approaches an object which is a target of monitoring, from the monitor image;
characteristic amount detection means for detecting amount of characteristics of the approaching individual from the image of the face of the approaching individual;
recording control means for controlling recording of characteristic amount data indicating the characteristic amount of the approaching individual, on recording means;
identifying means for identifying the approaching individual by collating the characteristic amount data on the approaching individual with characteristic amount data on an approaching individual detected in the past and recorded on the recording means; and
judging means for judging whether or not the approaching individual is a suspicious individual, on the basis of the frequency with which the image of the face of the identified approaching individual is detected within a predetermined period of time.

Abstract
A suspicious individual can be detected more accurately. A face detecting unit detects a face image of an approaching individual from a monitor image, and a characteristic amount detecting unit detects the characteristic amount of the approaching individual from the face image. A collating unit identifies an approaching individual by collating the characteristic amount of the approaching individual with the characteristic amount of an authorized individual which is recorded in an authorized individual information recording unit and the characteristic amount of a previously detected individual which is recorded in an approach information recording unit. An approaching activity detecting unit and an abnormal activity detecting unit compute the degree of suspiciousness of the approaching individual on the basis of the frequency with which the approaching individual approaches a target of monitoring, time at which the approaching individual approaches a target of monitoring, distance by which the approaching individual approaches a target of monitoring, and the like. A suspiciousness degree judgment unit judges whether the approaching individual is a suspicious individual or not, on the basis the degree of suspiciousness. The present invention can be applied to an on-vehicle monitoring system.
