Collation/retrieval system, collation/retrieval server, image feature extraction apparatus, collation/retrieval method, and program
First Claim
1. A collation apparatus comprising:
- a storage device configured to store a plurality of image features of collation areas extracted from a plurality of objects and management information corresponding to the plurality of objects in a mutually associated manner;
a memory configured to store instructions; and
a processor coupled to the memory and configured to execute the instructions to;
obtain an image including a reference section and a collation area of an object to be collated;
retrieve, from the stored plurality of image features, an image feature having the highest similarity to an image feature of collation area of the object to be collated; and
output management information about an object stored in the storage device corresponding to the image feature having the highest similarity, whereinthe management information about the object is not used for collation of the object and includes at least one of a production site, a producer name, a lot number, a production date, a quality information, a shipping point, and a ship date of the object.

4. A collation method performed by a processor executing instructions stored on a memory coupled to the processor, comprising:
-
obtaining an image including a reference section and a collation area of an object to be collated; retrieving an image feature having the highest similarity to an image feature of collation area of the object to be collated from a plurality of image features of collation areas extracted from a plurality of objects and stored in a storage device, wherein the storage device stores the plurality of image features and management information corresponding to the plurality of objects in a mutually associated manner; and outputting management information about an object stored in the storage device corresponding to the image feature having the highest similarity, wherein the management information about the object is not used for collation of the object and includes at least one of a production site, a producer name, a lot number, a production date, a quality information, a shipping point, and a ship date of the object. - View Dependent Claims (5, 6)
