Tiling Projection Blend Width Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image projection systems face difficulties in easily setting up tiling projections due to the need for users to designate the blend width, which can result in poor image quality or joint smoothness issues unless the characteristics of the blend width are understood.
Innovation Solution
A display method that allows users to select the size of the projection range, automatically determining the blend width and projecting patterns representing the overlapping area using two projectors, enabling seamless image alignment without requiring users to manually designate the blend width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user designates the blend width manually, then the projection setup can be completed, but the operation becomes difficult for ordinary users who do not understand the characteristics of blend width
Solution Approach 1:
The system automatically determines the blend width based on the projection range information selected by the user, eliminating the need for users to manually specify technical parameters they do not understand. The projectors self-adjust their overlapping areas to achieve seamless image joints without requiring user expertise in blend width characteristics.
Solution Approach 2:
The system changes the parameter determination method from manual user input to automatic calculation based on projection range. By selecting the projection range as the input parameter instead of blend width, the system simplifies the setup process while maintaining optimal image quality through automated parameter derivation.
2Area of stationary object
If the blend width is too narrow, then the projection range is maximized, but the smoothness in joints between images is spoiled
Solution Approach 1:
The system projects patterns representing the overlapping area to provide visual feedback for alignment. This feedback mechanism ensures that the automatically determined blend width achieves the desired joint smoothness while maintaining the projected image quality.
Solution Approach 2:
The system performs preliminary alignment using projected patterns before final image projection. By pre-establishing the correct overlapping area through pattern alignment, the system ensures both optimal projection range and joint smoothness are achieved simultaneously.
3Manufacturing precision
If the blend width is too wide, then the joint smoothness is improved, but the projection range becomes small and image quality degrades
Solution Approach 1:
The system optimizes the blend width parameter by determining it automatically based on the selected projection range, rather than allowing arbitrary wide overlaps. This parameter optimization ensures the minimum necessary blend width is used to maintain joint smoothness while preserving maximum projection range and image quality.

AI summary
A display method including an adjustment of a combined image includes receiving selection of information representing a size of a projection range when performing tiling projection of a first image projected using a first projector and a second image projected using a second projector, projecting a third image including a pattern representing a width of an overlapping area based on the information representing the size of the projection range using the first projector, and projecting a fourth image including a pattern representing the width of the overlapping area using the second projector.
