Commodity recognition apparatus and commodity recognition method
First Claim
Patent Images
1. A commodity recognition apparatus, comprising:
- a feature amount detection module configured to detect an appearance feature amount of a commodity included in an image captured by an image capturing unit;
a commodity candidate extraction module configured to extract a candidate of the commodity included in the image by comparing the data of the appearance feature amount detected by the feature amount detection module with the feature amount data in a recognition dictionary file storing feature amount data representing the surface information of a commodity for each commodity which is a recognition target;
a determination module configured to determine whether or not character recognition is required from the candidate of the commodity extracted as the candidate by the commodity candidate extraction module;
a character recognition module configured to recognize a character string included in the image captured by the image capturing unit, if the determination module determines that the character recognition is required; and
a commodity determination module configured to determine a commodity of a recognition target according to the character string recognized by the character recognition module and the candidate of the commodity extracted by the commodity candidate extraction module.

Abstract
A commodity recognition apparatus detects an appearance feature amount of a commodity included in an image captured by an image capturing unit, extracts a candidate of the commodity included in the captured image by comparing the data of the appearance feature amount with the feature amount data in a recognition dictionary file, recognizes a character string included in the image captured by the image capturing unit, and determines a commodity of a recognition target according to the recognized character string and the extracted candidate of the commodity.

6. A commodity recognition method, including:
-
detecting an appearance feature amount of a commodity included in an image captured; comparing the data of the detected appearance feature amount with a stored feature amount data representing surface information of a commodity for each commodity of a recognition target to extract a candidate of the commodity included in the image captured; determining whether or not character recognition is required from the candidate of the commodity extracted as the candidate; recognizing a character string included in the image captured, if it is determined that the character recognition is required; and determining a commodity of the recognition target according to the recognized character string and the candidate of the extracted commodity.

7. A commodity recognition apparatus, comprising:
-
an interface which captures an image captured by a camera; and a processor, the processor executing the following; detecting an appearance feature amount of a commodity included in the image captured by the camera; comparing data of the appearance feature amount of the commodity with feature amount data in a recognition dictionary file storing feature amount data representing surface information of a commodity for each commodity which is a recognition target; determining whether or not the character recognition is required from the candidate of the commodity extracted as the candidate; recognizing a character string included in the image captured by the camera, if the determination module determines that the character recognition is required; and determining a commodity of a recognition target from the candidate of the commodity according to the character string recognized. - View Dependent Claims (8, 9, 10)
