Cross-arranged Optical Machines for Circular Screen Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projectors struggle to achieve full coverage of small and micro spaces due to the short distance between the optical machine and the circular-screen projection surface, requiring special optical machines with short focal lengths, which limits their applicability in compact environments.
Innovation Solution
A projection method and system that employs a cross-arrangement of optical machines to optimize their placement, using common focal length machines to achieve seamless, multi-directional circular-screen coverage by calculating and adjusting the spatial position and rotation angles of each optical machine based on maximum optical path distance and setting parameters.

Engineering Contradiction Analysis
1Device complexity
If a conventional projector uses a common focal length optical machine, then the device complexity and hardware cost are reduced, but the projection coverage is insufficient for small and micro spaces due to the short distance between the optical machine and the circular-screen projection surface
Solution Approach 1:
The projection system divides the circular-screen projection surface into multiple projection areas, with each optical machine responsible for projecting onto a specific segment. This segmentation allows multiple optical machines to work cooperatively to achieve full coverage of the circular screen in small spaces without requiring each individual machine to have complex short-focal-length optics.
Solution Approach 2:
Multiple optical machines with common focal lengths are combined in a cross-arrangement configuration, where each machine projects onto a different segment of the circular screen. The projections are merged to form a complete panoramic image, achieving the coverage of a specialized short-focal-length system while using standard optical machines.
2Adaptability or versatility
If the distance between the optical machine and the circular-screen projection surface is shortened to fit small spaces, then the adaptability to compact environments is improved, but the projection coverage and image quality deteriorate
Solution Approach 1:
The system transitions from a single-point projection approach to a multi-point cross-arrangement configuration. By distributing multiple optical machines at different positions and angles around the projection space, the system achieves comprehensive coverage of the circular screen without requiring any single machine to be positioned extremely close to the screen.
Solution Approach 2:
The cross-arrangement configuration with multiple optical machines provides universal adaptability to various small space environments. The system can be adjusted and configured for different room sizes and screen positions while maintaining consistent projection quality and coverage, making it universally applicable rather than requiring specialized short-focal-length machines for each specific application.
3Area of stationary object
If multiple optical machines are arranged to achieve surrounding projection in small spaces, then the projection coverage is improved, but the device complexity and arrangement optimization difficulty increase
Solution Approach 1:
The cross-arrangement configuration employs asymmetric positioning of optical machines relative to the circular screen, with each machine placed at optimized angles and distances to maximize coverage of its assigned projection segment. This asymmetric arrangement, rather than symmetric uniform distribution, allows each machine to be optimally positioned for its specific projection task, simplifying the overall system design while achieving complete coverage.

AI summary
The projection method obtains a circular-screen projection surface by dividing a visual platform to be projected, arranges each optical machine to be arranged according to maximum optical path distance information that each optical machine to be arranged projects an image onto each circular-screen projection surface to obtain a first projection coverage range, and adjusts the first projection coverage range according to setting parameters corresponding to each optical machine to be arranged and in accordance with a preset projection surface to obtain a second projection coverage range. The projection method calculates geometric parameters and the second projection coverage range of each optical machine to be arranged to obtain a spatial position and a rotation angle range of each optical machine to be arranged.
