Multi-Projector Control Interface for Image Alignment and Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image projection systems face challenges in efficiently setting up projector positions for multi-projection displays, particularly when dealing with multiple layers, as users need to manually switch screens and confirm projector availability, which is time-consuming and cumbersome.
Innovation Solution
A control method for an image projection system that includes a first and second projector group, with a setting screen displaying regions for setting projector positions, allowing users to select and arrange projectors, and providing functions like screen matching, tiling assist, and stacking assist to align images and adjust settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually switch screens and confirm projector availability for each projector replacement, then projector position settings can be adjusted, but the setup time increases significantly
Solution Approach 1:
The system pre-displays a setting screen showing all projectors and their current positions before any replacement operation. This allows users to plan and execute projector reassignments in advance without needing to switch screens during the process, significantly reducing setup time while maintaining operational flexibility
Solution Approach 2:
The system creates a visual copy of the projector arrangement on the setting screen, allowing users to simulate and confirm position changes before actually implementing them. This virtual representation eliminates the need for physical screen switching and provides immediate feedback on the impact of each projector reassignment
2Reliability
If users switch screens to confirm projector availability for replacement, then accurate projector assignment can be ensured, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The setting screen serves multiple functions simultaneously: it displays the current projector arrangement, shows available projectors for replacement, provides drag-and-drop interface for reassignment, and confirms the impact of position changes. This multi-functional display eliminates the need for multiple separate screens and simplifies the entire projector configuration process while maintaining high accuracy
Solution Approach 2:
The system provides immediate visual feedback on the setting screen showing how projector reassignments will affect the overall display arrangement. Users can see the predicted outcome of each change before committing, ensuring accurate assignment while making the operation intuitive and error-free
3Manufacturing precision
If projectors of the same model or same function are disposed in respective layers for stack projection, then unevenness in multi-projection screen can be suppressed, but the determination process takes more time
Solution Approach 1:
The setting screen uses visual indicators (such as color coding or highlighting) to show projectors that are suitable for each layer based on their model and function characteristics. This visual differentiation helps users quickly identify compatible projectors without manually evaluating each one, reducing determination time while ensuring proper layer assignment for uniform display

AI summary
A range of images projected by a first projector group and a range of images projected by a second projector group are set to coincide with each other. A first setting screen including a first region for setting positions of images projected by a respective plurality of projectors included in the first projector group and a second region for setting positions of images projected by a respective plurality of projectors included in the second projector group is displayed. Operation by a user on the first setting screen is received. The positions of the images projected by the respective plurality of projectors included in the first projector group and the positions of the images projected by the respective plurality of projectors included in the second projector group are set.
