Commodity recognition apparatus and commodity recognition method

摘要

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.

主权项

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.
