SUSPICIOUS BEHAVIOR DETECTION SYSTEM AND METHOD
First Claim
Patent Images
1. A suspicious behavior detection system comprising:
- a sensor means for detecting movement of a monitored subject;
an ambulatory path acquisition means which acquires information about an ambulatory path of the monitored subject, based on the output of the sensor means;
a behavioral identification means which identifies behavior of the monitored subject, based on the ambulatory path information acquired by the ambulatory path acquisition means, by using learned information obtained by learning behavior along the ambulatory path; and
a determination means which automatically determines suspicious behavior of the monitored subject in real time, based on the behavior identified by the behavioral identification means.

Abstract
There is provided a suspicious behavior detection system capable of specifying and identifying a suspicious person exhibiting abnormal behavior. A suspicious behavior detection system is a system to detect suspicious behavior of a monitored subject, by using images captured by a stereo camera. The suspicious behavior detection system has an ambulatory path acquisition unit which acquires ambulatory path information of the monitored subject, and a behavioral identification unit which identifies behavior of the monitored subject based on the ambulatory path information, and automatically determines suspicious behavior of the monitored subject.

12. A suspicious behavior detection method adapted to a suspicious behavior detection system using a sensor means for detecting movement of a monitored subject, the suspicious behavior detection method comprising:
-
a step of acquiring information about an ambulatory path of the monitored subject, based on the output of the sensor means; a step of identifying behavior of the monitored subject, based on the ambulatory path information, by using learned information acquired by learning behavior along the ambulatory path; and a step of automatically determining suspicious behavior of the monitored subject in real time, based on the behavior identified by the behavioral identification means.
