3D Model Generation for Custom Decorative Sheet Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for customizing product covers, such as those described in JP 2010/532020 A and JP 2008/541246 A, are limited to pre-registered products, requiring time and effort to input product information like manufacturer and model name.
Innovation Solution
An information processing apparatus and system that acquires an image of an article, generates a three-dimensional model of the article, and arranges a design on the model's surface to generate image data for printing on a pressure-sensitive adhesive sheet, allowing for easy customization of seals or covers for any article.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a product cover customization system is implemented using pre-registered product information, then the customization function can be provided for specific products, but the system cannot be applied to arbitrary articles and requires time-consuming manual input of product information
Solution Approach 1:
The system creates a three-dimensional digital model (copy) of the physical article using image capture and processing. This digital model serves as a virtual representation that can be stored and reused for future customization operations, eliminating the need for repeated manual input of product information and enabling quick application of designs to the same or similar articles.
Solution Approach 2:
The manual mechanical process of inputting product information (typing, selecting from lists) is replaced by an automated optical system. The image acquisition device captures the article, and image processing algorithms automatically extract geometric features to generate the three-dimensional model, substituting human-operated mechanical data entry with automated computational processes.
2Measurement precision
If manual input of product information is required for customization, then accurate product identification can be achieved, but the customization process becomes time-consuming and labor-intensive
Solution Approach 1:
The manual mechanical process of product identification through information input is replaced by an automated optical measurement system. Image acquisition devices capture the article's visual characteristics, and image processing algorithms automatically analyze these images to extract geometric features and generate accurate three-dimensional models, achieving both precision and speed.
Solution Approach 2:
The system performs self-identification of the article by automatically analyzing its own visual characteristics. The image processing unit extracts geometric features directly from captured images without requiring external product information databases or manual input, enabling the system to autonomously identify and model the article for customization.
3Adaptability or versatility
If a three-dimensional model generation system using image processing is implemented, then customization can be applied to any article shape, but the system complexity increases
Solution Approach 1:
The complex task of three-dimensional model generation is segmented into distinct functional modules: image acquisition (capturing multiple views), image processing (extracting geometric features from images), and model generation (constructing the three-dimensional representation). This modular segmentation manages system complexity by organizing functions into separate, manageable components that can be developed and maintained independently.

AI summary
An information processing apparatus, an information processing program, and a system and a method for manufacturing a decorative sheet which can be applied for any article and easily customize a seal, a cover, or the like that covers the article. An information processing apparatus is applied to a system that manufactures a decorative sheet, which is attached to an article to decorate the article, and includes an acquisition unit, a model generation unit, and an image generation unit. The acquisition unit acquires an image of the article. The model generation unit generates a three-dimensional model of the article based on the image of the article. The image generation unit arranges a design on at least a part of a surface of the three-dimensional model, and generates image data for printing the arranged design on a pressure-sensitive adhesive sheet.
