摘要： An apparatus of this invention is directed to an information processing apparatus that effectively counts, on a type basis, articles of a plurality of types displayed in a depth direction on a display shelf. The information processing apparatus includes a display count acquirer that acquires display count information of articles using article presence/absence sensors provided on the display shelf on which the articles are placed, an article identifier that acquires article identification information capable of identifying the types of articles based on an image acquired by capturing the display shelf, and a display recognizer that recognizes, based on the display count information and the article identification information, display count of each type of the articles.

摘要： An article management system according to the present invention includes: a reader antenna (102) including an open-type transmission line terminated in an impedance matched state; an RF tag (104) that is placed at a location that is electromagnetically coupled to the reader antenna (102) and is visible from the reader antenna (102) in a state where a management target article (105) is placed in the vicinity of the RF tag; a management target article arrangement region in which the management target article (105) is placed, the management target article arrangement region being set in a location where the management target article (105) is electromagnetically coupled to a tag antenna of the RF tag (104); and an RFID reader (103) that sends a transmitted signal to the reader antenna (102) and receives a response signal output from the tag antenna via the reader antenna (102). The presence or absence of the management target article (105) is detected by detecting a change in operating characteristics of the tag antenna due to the management target article based on a change in intensity or phase of a reflected signal from the RF tag (104).

摘要： An object detection system includes a reader waveguide (101) formed as an open transmission line, an RFID tag (102) placed above the reader waveguide (101), a signal strength acquisition unit (103) that acquires signal strength of a read signal read from the RFID tag (102) by electromagnetic coupling through the reader waveguide (101), and an object detection unit (104) that detects physical characteristics of an object (105) corresponding to the acquired signal strength based on a relationship between a plurality of (three or more values of) signal strength of the read signal and physical characteristics of the object to be detected.
