Patent Document ID: 9454708
Application ID: 14285688

Base Claim:
1. A recognition dictionary creation apparatus, comprising: an image capturing section configured to photograph a commodity to capture the image of the commodity; a measurement module configured to measure a distance from the image capturing section to the commodity photographed by the image capturing section; a specifying module configured to specify the commodity; a storage module configured to store a correction coefficient for representing an attenuation trend of light reflected by a surface of the commodity having a standard figure when photographing the commodity at each separation distance from the image capturing section; a generation module configured to generate a quasi-commodity-image in a state in which the commodity is imaginarily moved away from the image capturing section to a given registration distance longer than the distance measured by the measurement module based on the image of the commodity photographed by the image capturing section; a correction module configured to correct the quasi-commodity-image generated by the generation module with the correction coefficient for the registration distance; an after-generation extraction module configured to extract an appearance feature amount of the commodity from the quasi-commodity-image generated by the generation module, wherein the after-generation extraction module extracts the appearance feature amount of the commodity from the quasi-commodity-image corrected by the correction module; and an after-generation registration module configured to register, in a recognition dictionary in association with the registration distance, the appearance feature amount extracted by the after-generation extraction module as the feature amount data of the commodity specified by the specifying module at the registration distance.

Claim 2:
2. The recognition dictionary creation apparatus according to claim 1 , further comprising: an acquisition module configured to acquire the appearance shape of the commodity photographed by the image capturing section; wherein the storage module stores, for each standard figure, a correction coefficient for representing the attenuation trend of each light reflected by the surfaces of objects having different standard figures when photographing the objects at each separation distance from the image capturing section, and the correction module corrects the quasi-commodity-image with a correction coefficient of a standard figure similar to the appearance shape acquired by the acquisition module.
