Leftover object detection device, leftover object detection method, and leftover object detection program

摘要

PROBLEM TO BE SOLVED: To prevent erroneous detection of a moving object as a leftover object. A left-over object detection device 10 detects a left-over object left in a photographing region based on photographed image data obtained by photographing a photographing region with a photographing device. The background difference calculation unit 22 calculates background difference information indicating a region having a difference between the target captured image data and the background image data, for each of the captured image data of a plurality of frames. The left-behind object detection unit 23 detects, as the left-behind area where the left-behind object is, an area indicating that there is a difference in the background difference information calculated for the captured image data of the reference number or more.
