Solution Overview

Problem

Three-dimensional modeling of objects requires high-end capturing devices, high-quality photographing environments, long reconstruction periods, and high manual post-processing costs, leading to high costs and potential reconstruction failures for reflective, transparent, and less textured articles, and NeRF solutions face long training times and low PSNR with cloud noise issues.

Innovation Solution

A low-cost three-dimensional information presentation method using common image capturing devices like mobile phones, combined with SLAM, AR, and data processing technologies, to capture and transform images into multiple viewing angles, reducing costs and improving presentation quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If three-dimensional reconstruction technology is used to present three-dimensional information, then the presentation quality is improved, but the cost and complexity increase significantly

Engineering Contradiction:
Improvethree-dimensional information presentation qualityVSAvoidcapturing device requirements
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent segments the three-dimensional information capture process into multiple two-dimensional image captures from different viewing angles. Instead of using a complex three-dimensional reconstruction system, it divides the task into capturing images at multiple positions around the article, then synthesizes these 2D images to create the 3D presentation effect.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent uses multiple two-dimensional copies (images) of the article from different angles to represent and reconstruct the three-dimensional information. By capturing and processing multiple 2D image copies, the system achieves 3D presentation without requiring complex 3D scanning hardware.

Inventive Principle:
Principle #26Copying

2Manufacturing precision

If three-dimensional reconstruction technology is used, then the presentation quality is improved, but the time and cost for reconstruction increase

Engineering Contradiction:
Improvethree-dimensional information presentation qualityVSAvoidreconstruction period
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent performs preliminary actions by capturing multiple images from different viewing angles in advance. These pre-captured images are then used to generate the three-dimensional presentation, eliminating the need for time-consuming real-time reconstruction processing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

By using multiple pre-captured two-dimensional image copies from different angles, the system avoids time-consuming 3D reconstruction algorithms. The presentation is generated by synthesizing these pre-existing image copies, significantly reducing processing time.

Inventive Principle:
Principle #26Copying

3Ease of manufacture

If conventional image capturing is used for three-dimensional reconstruction, then the equipment cost is reduced, but the reconstruction fails for reflective, transparent, and less textured articles

Engineering Contradiction:
Improvecapturing device accessibilityVSAvoidreconstruction success rate
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent changes the approach from attempting direct 3D reconstruction to capturing 2D images from multiple angular dimensions. By arranging image capturing positions at different viewing angles around the article, it captures information that conventional single-angle methods miss, improving success rate for challenging materials.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent applies local quality by using different image capturing positions with specific viewing angles tailored to capture different aspects of the article. Each capturing position is optimized for its specific angle, ensuring that reflective, transparent, and textured surfaces are all captured with appropriate lighting and perspective.

Inventive Principle:
Principle #3Local quality

4Manufacturing precision

If NeRF solutions are used for three-dimensional presentation, then the presentation quality is improved, but the training time increases and cloud noise appears

Engineering Contradiction:
Improvethree-dimensional presentation qualityVSAvoidtraining time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

Instead of using complex NeRF models that require extensive training, the patent uses a simpler, more direct approach of capturing and synthesizing images from pre-defined viewing angles. This lighter method avoids long training periods while still achieving high-quality 3D presentation.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent captures images from more viewing angles than the minimum required, ensuring comprehensive coverage of the article from all perspectives. This excessive sampling approach guarantees high-quality reconstruction without requiring complex training algorithms.

Inventive Principle:
Principle #16Partial or excessive action
