Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing techniques for projecting images on 3D structures are cumbersome, requiring repeated adjustments of projection display apparatuses in real space to match the desired image-projection state simulated in a virtual space, consuming significant time and effort.
Innovation Solution
A projection image adjusting system that includes a storage for virtual-environment setting information, a receiving section for real-environment setting information, and a controller to correct control set-up values, allowing for automatic adjustment of projectors to minimize the difference between the desired and actual image-projection states, thereby simplifying the installation and adjustment process.

Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustment of projection display apparatus is performed in real space to match the desired image-projection state, then the image projection accuracy is improved, but the time and effort required for installation and adjustment increases significantly
Solution Approach 1:
The patent creates a virtual space model that copies the real space environment, including the projection display apparatus and target object. By performing simulation and adjustment in this virtual copy, the system determines optimal control parameters without requiring repeated manual adjustments in the physical space, thereby reducing installation time while maintaining projection accuracy.
Solution Approach 2:
The system performs preliminary simulation and adjustment in the virtual space before actual installation in real space. The control parameters are optimized in advance through virtual environment testing, so that when the projection apparatus is deployed physically, minimal on-site adjustment is needed, significantly reducing the time and effort required for installation.
2Manufacturing precision
If repeated manual adjustment of lenses and apparatus position is performed, then the desired image-projection state is achieved, but the complexity of the installation process increases
Solution Approach 1:
The patent introduces a virtual space as an intermediary between the physical installation process and the final projection outcome. This virtual environment serves as a mediator where all complex adjustments, lens configurations, and positioning optimizations are performed through simulation, simplifying the actual physical installation process while achieving the desired projection state.
Solution Approach 2:
The system replaces the mechanical adjustment process (manual lens and apparatus repositioning) with a computational approach using virtual space simulation. Instead of physically moving components repeatedly, the system uses computer-based modeling and control parameter optimization to achieve the same adjustment objectives, thereby reducing installation complexity.
3Productivity
If simulation in virtual space is performed to determine optimal apparatus positioning, then the required adjustments in real space are minimized, but the system complexity increases due to virtual environment creation
Solution Approach 1:
The virtual space system performs multiple functions: it models the physical environment, simulates projection behavior, optimizes control parameters, and predicts installation outcomes. By consolidating these diverse functions into a single virtual environment platform, the system achieves high installation efficiency while managing complexity through functional integration rather than adding separate physical systems.

AI summary
The projection image adjusting system has a storage, a receiving section, and a controller. The storage stores virtual-environment setting information on a set-up situation of a projection display apparatus set so as to have a desired image-projection state on an object on which an image is projected in a virtual space created by a computer and also stores a control set-up value for the projection display apparatus in the desired image-projection state. The receiving section receives real-environment setting information on a set-up situation of the projection display apparatus in a real space. The controller controls the projection display apparatus in the real space. Based on the virtual-environment setting information and the real-environment setting information, the controller corrects the control set-up value so as to decrease a difference between an image-projection state in the real space and the desired image-projection state.
