Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques often fail to appropriately generate three-dimensional models of subjects from image data, leading to inaccuracies and incomplete representations.
Innovation Solution
An information processing apparatus and method that acquire an image of a specific object, utilize information indicating the object's shape, and capture angles to generate a three-dimensional model, incorporating a guiding model database for improved accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional image data processing is used to generate three-dimensional models, then the process is simple, but the model accuracy and completeness deteriorate
Solution Approach 1:
The patent introduces a guiding model database as an intermediary between the captured image and the final three-dimensional model. The guiding model provides prior shape information that guides the reconstruction process, acting as a mediator that bridges the gap between simple image data and accurate 3D models without requiring complex multi-view processing systems
Solution Approach 2:
The patent performs preliminary action by pre-storing three-dimensional shape information of reference objects in a guiding model database before the actual model generation. This pre-prepared shape information is then used to guide the reconstruction process, improving accuracy without adding complexity to the real-time processing system
2Loss of information
If multiple views and angles are captured to improve model completeness, then the model quality improves, but the amount of data and processing complexity increase
Solution Approach 1:
The patent uses a guiding model that contains pre-stored three-dimensional shape information as a template or copy. This guiding model is overlaid or combined with the captured image data, allowing the system to infer missing information from the reference shape without requiring additional captured images from multiple angles
Solution Approach 2:
The guiding model database serves multiple functions: it provides shape priors for reconstruction, fills in missing information from single-view images, and guides the alignment of captured data. This multi-functional approach reduces the need for separate processing steps that would otherwise require multiple images
