Portable Terminal Wine Label Recognition via Image Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in accessing wine information due to similar label designs for different wines, requiring professional knowledge to distinguish between them, and conventional barcode methods incur additional costs and complexity.
Innovation Solution
A method and apparatus using a portable terminal to recognize wine labels through image processing, extracting characters, detecting image characteristics, and matching them with a database to provide accurate and rapid wine information retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a barcode is attached to a wine label for recognition, then wine information can be retrieved, but additional expense is incurred and an additional barcode reader is required
Solution Approach 1:
The patent uses the existing wine label image as captured by the camera instead of requiring a separate barcode. The label image itself serves as the recognition source, eliminating the need for additional barcode stickers or dedicated barcode readers. The system processes the visual information already present on the label through image processing and character recognition techniques.
2Measurement precision
If professional knowledge is required to discriminate between wines with similar labels, then accurate wine identification can be achieved, but ease of operation deteriorates
Solution Approach 1:
The system performs automatic wine label recognition and information retrieval without requiring user expertise. The portable terminal automatically captures the label image, processes it through character recognition and image matching algorithms, and retrieves wine information from a database. This self-service approach eliminates the need for users to have professional wine knowledge while maintaining high identification accuracy.
3Quantity of substance
If wine information is provided through web-service, then comprehensive information can be accessed, but accessibility deteriorates due to time and location constraints
Solution Approach 1:
The portable terminal integrates multiple functions including camera capture, image processing, character recognition, database searching, and information display in a single device. This multi-functional system allows users to access comprehensive wine information anytime and anywhere by simply pointing the camera at the label, eliminating the need for continuous internet connection or specialized equipment while maintaining information completeness.

AI summary
Disclosed is a method for retrieving a label in a portable terminal. The method includes obtaining a label image photographed through a camera, extracting characters included in the label image and recognizing the extracted characters, detecting at least one label including the recognized character from a label database including multiple labels and information on the multiple labels and constituting a preliminary label candidate group including said at least one label, detecting an image characteristic of the label image, detecting at least one label having an image characteristic, which is similar with the detected image characteristic, from the preliminary label candidate group, and constituting a final label candidate group, and providing each of said at least one label included in the final label candidate group and detailed information corresponding to each of said at least one label.
