OBJECT IDENTIFICATION INFORMATION RECOGNITION SYSTEM AND METHOD, IMAGE INPUT DEVICE, AND OBJECT IDENTIFICATION INFORMATION RECOGNITION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an object identification information recognition system prevented from being restricted by a reading direction and a distance from an object identification information code when reading the object identification information code.

SOLUTION: The object identification information code comprising a plurality of feature points peculiar to the object and a first geometric invariant corresponding to the object identification code are produced, an image input device provides a plurality of images of the object added with the object identification information codes from a plurality of viewpoints, a plurality of independent images are produced out of the plurality of images, and feature points positions constituting the object identification information code are selected for the plurality of independent images. A second geometric invariant is calculated from the selected feature points positions and the object identification information code being the closest to the calculated second geometric invariant and corresponding to the first geometric invariant is detected.
