NUISANCE PERSON ESTIMATION SYSTEM AND CONTROL METHOD OF NUISANCE PERSON ESTIMATION SYSTEM

摘要

To provide a nuisance person estimation system capable of estimating a nuisance person in a space which a number of unspecific persons enter and exit.SOLUTION: In a nuisance person estimation system 500, a first imaging unit 501 takes an image of a person entering a space. A second imaging unit 502 is provided in the space and takes images of surroundings of its location in response to a notification signal from a notification terminal 503. An image analysis unit 504 extracts face data from the images taken by the first imaging unit 501 and the second imaging unit 502, and stores them into a first database unit 505 and a second database unit 506. A face data analysis unit 508 selects face data to be stored in a third database unit 507 by analyzing the face data in the first database unit 505 and the second database unit 506, and calculates a frequency score. A determination unit 509 estimates a person in the face data for which a corresponding frequency score exceeds a threshold value after elapse of a defined time period.SELECTED DRAWING: Figure 1
