Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Generating high-quality 2D images of virtual 3D models is challenging due to the difficulty in determining appropriate imaging parameters that mimic real-life images, especially in e-commerce platforms, which can be costly and time-consuming for merchants to achieve through traditional photo shoots.
Innovation Solution
A system determines virtual imaging parameters based on 2D images of other objects to generate consistent 2D images of virtual 3D models, incorporating aspects like viewpoint, orientation, lighting, and background setup, using techniques such as reverse engineering and machine learning to replicate desirable image qualities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional photo shoots are used to generate 2D images of virtual 3D models, then image quality can be maintained, but cost and time consumption increase significantly
Solution Approach 1:
The patent creates virtual copies of physical objects as 3D models, then generates 2D images from these digital replicas. This copying approach eliminates the need for repeated physical photo shoots while maintaining image quality, as the virtual 3D model can be rendered infinitely without additional time or resource investment.
Solution Approach 2:
The patent replaces the mechanical photography process (cameras, lighting equipment, physical setups) with computational rendering methods. By substituting physical imaging mechanisms with software-based 3D rendering, the system achieves comparable image quality without the time-consuming setup and execution of traditional photo shoots.
2Manufacturing precision
If traditional photo shoots are conducted to achieve desired image quality, then consistent imaging parameters can be obtained, but cost increases significantly
Solution Approach 1:
The patent extracts imaging parameters by creating virtual copies and comparing their rendered appearance against reference images. This digital copying and comparison process enables precise parameter determination without incurring the high costs of multiple physical photo shoots with professional equipment and personnel.
Solution Approach 2:
The patent substitutes expensive physical photography equipment and professional photo shoot operations with computational algorithms that analyze reference images and derive imaging parameters. This mechanical-to-computational substitution dramatically reduces costs while maintaining parameter consistency.
3Manufacturing precision
If virtual 3D models are rendered with accurate imaging parameters, then image quality improves, but the complexity of determining those parameters increases
Solution Approach 1:
The patent breaks down the complex task of determining imaging parameters into separate, manageable components: extracting parameters from reference images, creating virtual 3D models, rendering those models, comparing results, and iteratively adjusting parameters. This segmentation transforms an overwhelming complex problem into a systematic multi-step process.
Solution Approach 2:
The patent implements a feedback loop where rendered images from virtual 3D models are compared against reference images, and the differences inform adjustments to imaging parameters. This iterative feedback process automatically refines parameter accuracy without requiring complex manual analysis, as the system self-corrects based on visual comparison results.
