PROBLEM TO BE SOLVED: To accurately determine putting in/out of an article even in a case in which a plurality of articles are put in/out or an article is moved in a shed during a single opening/closing of a door, relating to management of an article in a storage shed.SOLUTION: A differential region between an in-shed image before operation for putting in/out or movement of an article in a storage shed and an in-shed image after the operation is extracted. Putting in or putting out of an article from a shed is determined based on the differential region and the in-shed image before operation and the in-shed image after the operation. Whether an operation is being made or not is determined from temporal change of the in-shed image. An image portion whose contour resembles the differential region is determined to be an image of an article that has been put in or put out of the shed. |
