Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for generating texture maps in computer-generated visual content, such as interactive video games, face challenges in producing high-quality, seamless texture maps that accurately represent the visual characteristics of three-dimensional objects, particularly human bodies, under varying lighting conditions and polarization patterns.
Innovation Solution
A lighting assembly and image processing workflow that includes multiple lighting fixtures with adjustable light intensity and polarization filters, synchronized with cameras to capture images under different illumination and polarization patterns, followed by image calibration, distortion correction, and blending operations to generate reflectance, photometric normal, displacement, and albedo maps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple lighting fixtures with adjustable intensity and polarization filters are used, then the quality and realism of texture maps are improved, but the device complexity increases
Solution Approach 1:
The lighting assembly is divided into multiple independent lighting fixtures, each equipped with adjustable intensity controls and polarization filters. This segmentation allows each fixture to be independently controlled to create specific illumination patterns, enabling high-quality texture map acquisition while maintaining modular complexity that can be managed through standardized interfaces and control systems.
2Measurement precision
If images are captured under different illumination and polarization patterns, then the accuracy of visual characteristics is improved, but the time required for image capture and processing increases
Solution Approach 1:
The system employs periodic action by systematically cycling through different illumination patterns and polarization configurations in a predetermined sequence. Multiple images are captured under varying conditions (different lighting angles, intensity levels, and polarization states), then processed through calibration and blending operations to produce accurate texture maps. This methodical periodic variation ensures comprehensive visual characteristic capture while maintaining efficient workflow through automated sequencing.
