SUSPICIOUS PERSON DETECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a suspicious person detection device for highly accurately detecting a suspicious person such as a push-in robber.

SOLUTION: The suspicious person detection device includes: an imaging part for successively obtaining images in a prescribed region; a tracking part for tracking persons on the images by each person image detected from the images and successively outputting position information of each person image; a detection part for detecting existence of the suspicious person; and an output part for outputting alarm when detecting the existence of the suspicious person. The detection part includes: relative position calculation means for calculating a relative position being relative position relation between the first person image and the second person image among the multiple person images when the tracking part detects the multiple person images; and determination means for determining the existence of the suspicious person when the relative position is substantially fixed over a prescribed time.
