Information acquisition apparatus
First Claim
1. An information acquisition apparatus having a sensing device configured to sense an object, and a reading device configured to read information of a tag attached to the object, comprising:
- an extracting device configured to extract information concerning a characteristic of an object in an image sensed by said sensing device;
a storage device configured to store the information of the tag attached to the object and predetermined information and the information concerning the characteristic of the object, such that the information of the tag corresponds to the information of the object; and
a discrimination device configured to discriminate a position of the object corresponding to the information of the tag read by said reading device, on the basis of the information concerning the characteristic of the object in the sensed image extracted by said extracting device and the information of the tag read by said reading device,wherein said discrimination device performs the discrimination on the basis of the information stored in said storage device.

Abstract
When a plurality of objects having RFID tags attached are to be read, an image sensing unit performs image sensing, and at the same time an RFID reader reads an RFID tag within the image sensing range. A characteristic quantity (external appearance model) of an object obtained from a database on the basis of ID data of the RFID tag is compared with a characteristic quantity obtained by image processing of the sensed image, thereby acquiring information unique to the object. The object is discriminably specified by superimposing the acquired unique information on the object in the sensed image.
