Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional 3D modeling techniques are used to generate high-quality free viewpoint videos, then the quality and accuracy of 3D representations are improved, but the processing time and system resource requirements increase significantly
Solution Approach 1:
The patent segments the 3D modeling process by dividing the scene into multiple depth layers or slices. Each layer is processed independently to generate 2D images, which are then composited to create the final 3D representation. This segmentation reduces the computational complexity of processing the entire scene at once, enabling faster generation while maintaining model accuracy.
Solution Approach 2:
The patent uses 2D image copies or projections as intermediaries to represent 3D information. Instead of directly computing complex 3D geometries from raw data, the system creates 2D representations that can be efficiently processed and then synthesized into 3D models, significantly reducing processing time while preserving essential spatial information.
2Manufacturing precision
If detailed 3D models are generated for high-quality video rendering, then the visual quality is improved, but the computational power and storage requirements increase
Solution Approach 1:
The patent applies partial action by processing only the necessary portions of the scene at high detail levels. Rather than rendering every element with maximum detail, the system selectively applies detailed 3D modeling to regions that require it, while using simplified representations for other areas, thus reducing overall computational power requirements while maintaining visual quality where needed.
3Speed
If real-time processing is implemented for live broadcasting, then the responsiveness is improved, but the processing quality and model accuracy may deteriorate
Solution Approach 1:
By segmenting the scene into multiple depth layers that can be processed in parallel, the system achieves real-time processing speeds while maintaining quality. Each layer is independently rendered and then combined, allowing for efficient utilization of processing resources and maintaining acceptable 3D representation quality under real-time constraints.

AI summary
A method and system for improving a three-dimensional (3D) representation of objects using semantic data. The method comprises receiving an input data generated in response to captured video in a filming area; setting at least one parameter for each region in the input data; and generating a 3D representation based in part on the at least one parameter and semantic data associated with the input data.
