Fulldome Display Mapping Method for Hardware Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fulldome display systems face increased hardware costs and inefficiencies when dealing with higher image resolutions, as they require a proportional increase in transmitting and receiving devices to handle the increased image pixels.
Innovation Solution
A mapping method that divides the deformed image into multiple images, allowing for efficient transmission and display by using a combination of first and second displaying modules with specific mapping relations, thereby reducing the need for additional hardware by incorporating and rearranging image pixels within existing modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the resolution of the original image and the fulldome display increases, then the image quality and viewing presence are improved, but the number of transmitting devices and receiving devices must be increased, leading to increased hardware cost
Solution Approach 1:
The patent divides the deformed image into multiple sub-images (first image, second image, third image) that correspond to different displaying modules. This segmentation allows the system to distribute image data across existing hardware modules rather than requiring additional devices, thereby maintaining high resolution while avoiding increased hardware complexity
Solution Approach 2:
The patent incorporates the third image with the second image to form an intermediate image, effectively utilizing the temporal or processing dimension to combine image data. This approach allows the system to handle increased image resolution by processing images in stages rather than requiring proportional increases in parallel hardware devices
2Productivity
If the number of transmitting devices and receiving devices is increased to handle higher resolution images, then the image transmission capability is improved, but the hardware cost increases
Solution Approach 1:
The patent makes existing displaying modules perform multiple functions by assigning different image portions to different modules and incorporating images across modules. The first, second, and third displaying modules work together in a coordinated manner, with each module handling specific portions of the high-resolution image, thereby achieving enhanced transmission capability without additional hardware investment
Solution Approach 2:
The patent merges the second image and third image to form an intermediate image that is then displayed on the second displaying module. This combining approach allows the system to utilize existing hardware resources more efficiently, achieving higher effective resolution and transmission capability without proportionally increasing hardware quantity or cost

AI summary
A mapping method for a fulldome display, including convert an original image into a deformed image corresponding to the fulldome display; divides the deformed image into at least one first image, at least one second image, and at least one third image; incorporate the third image with the second image to form at least one intermediate image; display image pixels of the first image on display pixels of at least one first displaying module of the fulldome display based on a first mapping relation; display image pixels of the intermediate image on display pixels of at least one second displaying module of the fulldome display based on a second mapping relation. In this way, the increased image pixels of the third image could be transmitted and be displayed.
