Article Verification Using Textured Pattern Image Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID-based verification technologies require high costs and are impractical for small items like fasteners, as they necessitate the installation of special devices such as IC tags, which is often unfeasible due to size constraints.
Innovation Solution
A verification method and system that utilizes a textured pattern on articles, where image features of the pattern are stored and matched against acquired images, eliminating the need for special devices like IC tags by designating a verification area on the article and using image feature comparison for verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID chips are installed in articles for verification, then verification capability is improved, but manufacturing cost increases and device complexity increases
Solution Approach 1:
The patent extracts the verification function from the article itself by utilizing the inherent textured pattern on the article surface. Instead of adding external verification devices like RFID chips, the solution uses the article's own texture characteristics as the verification medium, thereby eliminating the need for additional complex components while maintaining verification capability.
Solution Approach 2:
The patent creates a digital copy of the textured pattern's image features and stores them in a database. This digital replica serves as the verification reference, allowing the system to compare acquired images against the stored copy to authenticate the article without requiring physical RFID tags or other electronic components.
2Reliability
If RFID chips are installed in articles for verification, then verification capability is improved, but manufacturing cost increases
Solution Approach 1:
The article's textured pattern serves its dual purpose: it provides the article's functional surface characteristics and simultaneously acts as the verification identifier. The texture pattern inherently contains unique image features that can be captured and stored, eliminating the need for separate verification components and reducing manufacturing costs by utilizing what is already present on the article.
Solution Approach 2:
Instead of physically copying the article with RFID chips, the patent creates a digital copy of the textured pattern's image features. This digital replication is stored in a database and used for verification, significantly reducing manufacturing costs compared to installing physical RFID chips in each article.
3Reliability
If small articles like fasteners are verified using RFID chips, then verification capability is improved, but ease of manufacture deteriorates due to size constraints
Solution Approach 1:
The patent extracts the verification function from external components and embeds it within the article's surface texture itself. For small articles like fasteners, this means the verification capability is inherent in the textured pattern that is already part of the manufacturing process, eliminating the need to install separate RFID chips that would be difficult to attach to such small items.
Solution Approach 2:
The textured pattern on small articles serves the dual purpose of providing the article's surface characteristics and enabling verification. The unique image features of the texture pattern are captured and stored, allowing small articles to be verified without requiring additional components that would be challenging to manufacture or attach at their small scale.
