Engineering Contradiction Analysis
1Illumination intensity
If specialized mobile video projection equipment is used to project three-dimensional models onto real-world structures, then the visual display capability is improved, but distortion and loss of detail occur
Solution Approach 1:
The patent transforms the three-dimensional model into a two-dimensional reflection model through mathematical projection functions. This dimensional transformation allows the projection to accurately conform to the target structure's geometry, eliminating distortion and detail loss while maintaining high visual fidelity on complex surfaces like hemispherical domes.
Solution Approach 2:
The system applies mathematical projection functions that dynamically adjust projection parameters based on the target structure's geometric characteristics. By changing the projection parameters to match the specific geometry (e.g., hemispherical, cylindrical), the system achieves accurate mapping without distortion while preserving three-dimensional model details on two-dimensional projection surfaces.
2Adaptability or versatility
If projection mapping is used to fit images to building contours, then the adaptability to different structures is improved, but rendering errors and artifacts increase
Solution Approach 1:
The patent creates a reflection model that copies the essential geometric features of the target structure through mathematical transformation. This reflection model serves as an intermediate representation that preserves the structure's contours while eliminating rendering errors, allowing accurate projection across diverse building geometries without introducing artifacts.
Solution Approach 2:
The system replaces traditional geometric mapping mechanisms with mathematical projection functions. These functions compute the optimal projection transformation based on the target structure's geometry, substituting complex mechanical alignment processes with computational mathematics to eliminate rendering artifacts while maintaining high adaptability to different structures.
3Illumination intensity
If three-dimensional models are projected directly onto real-world structures, then the visual impact is improved, but distortion and loss of detail occur
Solution Approach 1:
The patent employs dimensional transformation by converting the three-dimensional model into a two-dimensional reflection model through mathematical projection. This transformation maintains all essential details and information from the original three-dimensional model while adapting it to the two-dimensional projection surface, preventing any loss of information during the projection process.
