Automated Article Appraisal Using 3D Scanning and Image Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for authentic articles, such as luxury goods and art, is hindered by the difficulty in determining authenticity, leading to a rise in fraudulent transactions due to the limitations of traditional appraisal methods that require professional appraisers and are restricted by time and location.
Innovation Solution
An apparatus that uses a camera, 3D scanner, and processing unit to analyze images and videos of articles, determining authenticity and evaluating their value based on characteristic point information, brand, type, and product information, regardless of the presence of professional appraisers, and provides product information and location-based services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If professional appraisers are used to determine article authenticity, then appraisal accuracy is improved, but time and location restrictions increase and accessibility decreases
Solution Approach 1:
The patent uses high-resolution image capture and 3D scanning to create digital copies of articles for analysis. The imaging unit captures detailed images from multiple angles, and the 3D scanning unit creates three-dimensional models, allowing the article's physical characteristics to be replicated digitally for automated authentication without requiring physical presence of expert appraisers
Solution Approach 2:
The patent replaces the mechanical system of human expert appraisal with an automated image processing and analysis system. The processing unit automatically extracts features from captured images, compares them against reference databases, and determines authenticity using algorithms, eliminating the need for physical human inspection while maintaining accuracy
2Device complexity
If traditional image photography methods are used, then equipment simplicity is improved, but measurement precision and detail capture deteriorate
Solution Approach 1:
The patent divides the imaging process into multiple segments: a main imaging unit for overall article capture, additional imaging units for specific detail areas, and a 3D scanning unit for spatial characteristics. This segmentation allows comprehensive detail capture while keeping each individual imaging component relatively simple
Solution Approach 2:
The patent combines multiple imaging technologies (2D photography, macro photography, and 3D scanning) into a single integrated appraisal system. The processing unit merges data from all imaging sources to create a comprehensive digital representation of the article, achieving high precision without requiring overly complex individual components
3Measurement precision
If comprehensive article analysis is performed, then appraisal accuracy is improved, but processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary organization of reference data in databases before actual appraisal. Reference images, 3D models, and authentication criteria are pre-processed and stored in structured formats, allowing the processing unit to quickly retrieve and compare against captured article data without time-consuming analysis during the appraisal moment
Solution Approach 2:
The patent extracts only the most critical authentication features from comprehensive article data. The processing unit identifies and extracts key characteristics such as serial numbers, unique patterns, and defining structural features for authentication, while separating less critical cosmetic details for separate evaluation, reducing processing complexity while maintaining accuracy
Data Source
AI summary
The present disclosure relates to an apparatus for appraising an article. The apparatus for appraising an article includes: a communication unit receiving a photographed image including a partial image an entire image of the article; and a processing unit analyzing the photographed image, extracting characteristic point information of the photographed image based on a result of the analyzing of the photographed image, comparing the characteristic point information with reference information for the article to determine authenticity and an appearance grade of the article, and calculating an evaluation amount of the article based on the authenticity and the appearance grade of the article.
