RECOGNITION DICTIONARY CREATION APPARATUS AND METHOD FOR CREATING RECOGNITION DICTIONARY BY THE SAME
First 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 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;
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; and
an after-generation registration module configured to register, in a recognition dictionary in association with the registration distance data, 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.

Abstract
A recognition dictionary creation apparatus photographs a commodity by an image capturing section to capture the image of the commodity; measures a distance from the image capturing section to the commodity photographed by the image capturing section; generates 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 measurement distance based on the image of the commodity photographed by the image capturing section; extracts an appearance feature amount of the commodity from the generated quasi-commodity-image; and registers, in a recognition dictionary in association with the registration distance data, the extracted appearance feature amount as the feature amount data of the photographed commodity at the registration distance to create the recognition dictionary.

6. A method for creating a recognition dictionary by a recognition dictionary creation apparatus having an image capturing section, including:
-
photographing a commodity by the image capturing section to capture the image of the commodity; measuring a distance from the commodity to the image capturing section; specifying the commodity; generating 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 measured distance based on the image of the commodity photographed by the image capturing section; extracting an appearance feature amount of the commodity from the generated quasi-commodity-image; and registering, in a recognition dictionary in association with the registration distance data, the extracted appearance feature amount as the feature amount data of the specified commodity at the registration distance to create the recognition dictionary.
