Abstract
The present invention provides a technology that can reduce erroneous detection and detect a suspicious person from an image at high accuracy. A suspicious person detection device according to one example embodiment of the present invention includes: an eye direction detection unit that detects an eye direction of a subject; a face direction detection unit that detects a face direction of the subject; an environment information acquisition unit that acquires environment information indicating arrangement of an object around the subject; and a determination unit that, based on the face direction, the eye direction, and the environment information, determines whether or not the subject is showing suspicious behavior.
Claims20
A suspicious person detection device comprising:
- a memory configured to store instructions;
- and
- a processor configured to execute the instructions to:
- detect an eye direction of a subject;
- detect a face direction of the subject;
- and
- determine that the subject is showing suspicious behavior when the face direction is oriented to a position of an object around the subject, and a difference between the face direction and the eye direction is greater than a predetermined threshold.
(canceled)
