Projection Image Adjustment System with Automated Imaging Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing projection image adjustment systems require significant time and effort for users to determine which imaging apparatuses cover the projection image of projection display apparatuses, making it difficult to adjust the image shape or characteristics effectively.
Innovation Solution
A projection image adjustment system comprising multiple projection display apparatuses, imaging apparatuses, and a controller with an imaging-apparatus selecting unit, shooting-region setting unit, pattern projection unit, and shot-image display unit, allowing users to easily check and adjust the projection regions, positions, and selection of imaging apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users manually determine which imaging apparatuses cover which projection images, then the system can establish correspondence between imaging apparatuses and projection display apparatuses, but the adjustment process requires significant time and effort
Solution Approach 1:
The system automatically determines correspondence between imaging apparatuses and projection display apparatuses by having each imaging apparatus shoot the projection image and the controller identify which projection display apparatus corresponds to which imaging apparatus based on the shot images, eliminating the need for manual user determination
Solution Approach 2:
The controller displays the shot image from each imaging apparatus to provide visual feedback, allowing users to easily verify whether the imaging apparatus is involved in the projection region, thereby streamlining the adjustment process
2Manufacturing precision
If users manually check and adjust projection regions and imaging apparatus positions, then the projection image can be properly adjusted to desired shape or characteristics, but the operation becomes complex and time-consuming
Solution Approach 1:
The system automatically determines the correspondence between imaging apparatuses and projection display apparatuses through automated image shooting and identification processes, reducing the operational burden on users while maintaining precise adjustment capability
Solution Approach 2:
The controller provides visual feedback by displaying shot images and indicating which projection display apparatuses are involved in each imaging apparatus's field of view, enabling users to easily verify and adjust settings without complex manual procedures

AI summary
The projection image adjustment system includes: projection display apparatuses for projecting projection images; a first and a second imaging apparatus for shooting the projection images; and a controller. The controller includes: an imaging-apparatus selecting unit, a shooting-region setting unit, a pattern projection unit, and a shot-image display unit. The imaging-apparatus selecting unit selects the first or the second imaging apparatus. The shooting-region setting unit sets a first and a second charge-of-shoot region for a projection display apparatus. The first and the second imaging apparatus are respectively in charge of shooting the first and the second charge-of-shoot region. At least one projection display apparatus is shared by the first and second charge-of-shoot regions. The pattern projection unit projects a format pattern of the projection display apparatus corresponding to the first or the second charge-of-shoot region. The shot-image display unit displays an image of the first or the second imaging apparatus.
