3D Architecture Projection System with Matte Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image projection systems struggle to project images onto non-coplanar and non-adjacent surfaces without optical distortion, limiting their ability to display images on complex three-dimensional architectures such as multiple surfaces joined at corners, and require manual manipulation and multiple projectors for accurate representation.
Innovation Solution
A method and system using a video compositing application to project images onto three-dimensional architectures by securing a projector in a fixed orientation, coupling it with a computer device, and adjusting mattes within the composition window to align edges of the projected image with the architecture's surfaces, while compensating for optical distortions through tools like rotating, scaling, and skewing, allowing for simultaneous projection onto multiple non-contiguous surfaces.

Engineering Contradiction Analysis
1Adaptability or versatility
If conventional projection systems are used to project images onto non-coplanar and non-adjacent surfaces, then the projection can be achieved, but optical distortion of the image occurs
Solution Approach 1:
The projection system divides the complex three-dimensional architecture into multiple separate projection surfaces (e.g., individual walls, ceilings, floors). Each surface is projected onto separately using distinct projection devices or separate projection sequences, allowing each surface to be optimized individually for distortion-free projection while collectively covering the entire architecture.
Solution Approach 2:
The system transitions from traditional two-dimensional flat surface projection to three-dimensional architectural surface projection. By incorporating depth and spatial orientation dimensions, the system can project onto non-coplanar surfaces at various angles and orientations, enabling immersion in the architectural space while maintaining image quality through computational correction.
2Area of stationary object
If multiple projection devices are used to project onto multiple non-contiguous surfaces, then coverage area increases, but system complexity increases
Solution Approach 1:
The projection system employs universal projection devices that can project onto multiple types of surfaces (flat, curved, angled, non-coplanar) with a single device. This multi-functionality allows one projector to replace multiple specialized projectors, reducing system complexity while maintaining comprehensive coverage of various architectural surfaces.
Solution Approach 2:
The system introduces an intermediary computational processing layer that receives the projection content, analyzes the target architectural surfaces, applies distortion correction algorithms, and generates corrected projection images. This intermediary software layer coordinates multiple projection devices, managing their operation and synchronization, thereby reducing the operational complexity despite increased hardware quantity.
3Manufacturing precision
If manual manipulation is performed to align projection images on adjacent surfaces, then distortion correction is achieved, but operation time increases
Solution Approach 1:
The projection system incorporates feedback mechanisms where sensors or cameras capture the actual projection output on the architectural surfaces, compare it with the desired alignment, and automatically adjust projection parameters (angle, position, distortion correction) to achieve precise alignment. This closed-loop feedback system eliminates manual trial-and-error adjustment, achieving accurate alignment quickly and consistently.
Solution Approach 2:
The system performs preliminary scanning and mapping of the architectural surfaces before projection begins. By pre-characterizing the geometry, orientation, and position of each surface, the system can pre-calculate the required distortion correction and alignment parameters, eliminating the need for time-consuming manual adjustment during actual projection setup.
