Ordered Mapping on 3D Projection Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional displays are unable to effectively transmit visual media to unordered arrays of light sources, requiring manual mapping which is time-consuming and impractical, especially in scenarios with 3D structures wrapped in fiber optic light sources.
Innovation Solution
A computer-implemented method generates a 3D computer model of the display surface, creates a map of light emission locations, and uses a lookup table to correlate pixels of the visual media with light sources, allowing signals to be transmitted directly to unordered light sources without manual mapping, utilizing techniques like UV texture mapping and gray code lookup tables.

Engineering Contradiction Analysis
1Productivity
If manual mapping is used to transmit visual media to unordered arrays of light sources, then the display can present visual media, but the process is time-consuming and impractical
Solution Approach 1:
The system performs automatic mapping where the display device itself correlates light source locations with visual media pixels using image capture and pattern recognition, eliminating the need for external manual mapping. The processor automatically generates the correspondence information by analyzing captured images of the display surface.
Solution Approach 2:
The patent replaces manual mechanical mapping processes with automated optical and computational methods. Image capture devices photograph the display surface, and computational algorithms automatically correlate light source positions with pixel locations, substituting human-operated mechanical mapping with automated opto-electronic systems.
2Adaptability or versatility
If conventional display methods are used with ordered light sources, then the mapping process is straightforward, but the system cannot effectively handle unordered arrays of light sources
Solution Approach 1:
The patent creates a universal mapping system that can handle both ordered and unordered arrays of light sources through the same automated process. The image capture and pattern recognition methodology works regardless of whether light sources are arranged in a regular grid or scattered configuration, making the system adaptable to various display technologies including LEDs, fiber optics, and OLEDs.
Solution Approach 2:
The patent introduces an intermediary mapping system consisting of captured images and generated correspondence information that mediates between the visual media input and the unordered light source array. This intermediary layer of spatial correlation data allows the system to bridge the gap between ordered digital images and unordered physical light source positions.
3Manufacturing precision
If manual mapping is performed for each display configuration, then accurate visual media transmission is achieved, but the process is impractical for various types of light sources
Solution Approach 1:
The display system automatically performs the mapping task that would otherwise require manual intervention. By capturing images of the actual display surface and processing them through pattern recognition algorithms, the system self-generates the precise correspondence information needed for accurate visual media transmission without requiring manual configuration for each display setup.
Solution Approach 2:
The system performs preliminary mapping by capturing images and generating correspondence information before actual visual media presentation begins. This pre-established spatial correlation data is stored and reused for subsequent display operations, eliminating the need to perform mapping repeatedly for the same display configuration.
Data Source
AI summary
Systems and methods are provided for presenting visual media on a structure having a plurality of unordered light sources, e.g., fiber optic light sources, light emitting diodes (LEDs), etc. Visual media can be created based on a computer model of the structure. Images of the structure can be analyzed to determine the location of each of the light sources. A lookup table can be generated based on the image analysis, and used to correlate pixels of the visual media to one or more of the actual light sources. A visual media artist or designer need not have prior knowledge of the order/layout of the light sources on the structure in order to create visual media to be presented thereon.
