Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The generation of moiré patterns during virtual production is laborious and time-consuming due to the need for manual placement and analysis of cameras relative to display walls, which is unsatisfactory in a production environment.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual placement and analysis of cameras relative to display walls is performed, then accurate moiré pattern detection is achieved, but the process becomes laborious and time-consuming
Solution Approach 1:
The patent creates a virtual copy of the physical production set in a computer-generated environment. This virtual model includes digital representations of display walls, cameras, and targets. By analyzing moiré patterns in this virtual copy rather than performing manual physical analysis, the system maintains detection accuracy while dramatically reducing the time and labor required for set planning.
Solution Approach 2:
The patent replaces manual mechanical analysis methods with automated computer-based simulation. Instead of physically positioning cameras and manually analyzing moiré patterns, the system uses software to simulate camera positions, render virtual images, and automatically detect moiré patterns through algorithmic analysis, eliminating the need for labor-intensive manual procedures.
2Manufacturing precision
If comprehensive analysis of all camera positions is performed, then optimal camera locations are identified, but the complexity of the analysis process increases
Solution Approach 1:
The patent divides the continuous space of possible camera positions into a discrete grid of sample points. This segmentation allows the system to analyze specific predetermined locations systematically without overwhelming complexity. The virtual production set is also segmented into manageable computational elements that can be processed individually by the simulation system.
Solution Approach 2:
The patent performs preliminary virtual analysis of all potential camera positions before actual production begins. By pre-calculating moiré patterns for multiple positions in the virtual environment and generating heat maps showing risk areas, the system identifies optimal locations in advance, simplifying the actual on-set camera placement process.
