ARTICLE POSITION ESTIMATION DEVICE, ARTICLE POSITION ESTIMATION METHOD, ARTICLE SEARCH SYSTEM, AND PROGRAM FOR ARTICLE POSITION ESTIMATION

摘要

Information on the location and time of an article that is detected by an article detection device (101) is stored in an article management database (102), and information on the location and time of a person that is detected by a person detection device (103) is stored in a person management database (104). A means (107) for estimating an article presence region refers to the above pieces of information and estimates a possible location where the article is present. It is also possible that a means (108) for weighting an article position candidate performs weighting based on information on movement of the person and on the location where the article is usually placed.
