Projector Content Generation Using Virtual Space Reference Positions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Generating image content for projection systems is labor-intensive due to the need to constantly adjust for the relative positional relationship between the projector and the projection position, especially when the projection position changes, as it requires determining the size and shape of objects to maintain consistency across varying distances and orientations.
Innovation Solution
A method and system that acquire space information, display position information, and reference position information to generate image content in a virtual space, allowing for the projection of images with objects viewed from a reference position, thereby simplifying the generation process by decoupling the object's size and shape from the projector's position, using a content generation system with acquisition units and a generation unit to produce image content that can be projected at a real-space projection position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projection position changes in real space, then the flexibility and adaptability of the projection system is improved, but the complexity of generating image content increases due to the need to constantly adjust for relative positional relationships
Solution Approach 1:
The patent introduces a virtual space that corresponds to real space, adding a dimensional layer for content generation. By generating image content in this virtual space with predefined reference positions, the system decouples the complexity of real-space positional adjustments from the content generation process, allowing flexible projection positioning without increasing content generation complexity
Solution Approach 2:
The patent creates a virtual copy of real space where image content is generated. This virtual space serves as a simplified model that replicates the essential spatial relationships without the complexity of real-world positional variations, enabling consistent content generation across different projection positions
2Manufacturing precision
If the relative positional relationship between projector and projection position is adjusted to maintain constant object size, then the projection quality is improved, but the time and effort required for content generation increases
Solution Approach 1:
The patent establishes reference positions in the virtual space beforehand, before actual projection occurs. By pre-defining these reference positions and generating content relative to them, the system eliminates the need for time-consuming adjustments during deployment, as the content is already optimized for the desired projection quality
Solution Approach 2:
The reference position framework serves multiple functions simultaneously: it defines the viewing angle, determines object size scaling, and establishes spatial relationships all in one system. This multi-functionality allows the same reference position data to ensure projection quality across different positions without requiring separate adjustments for each parameter

AI summary
A content generation method generates image content to be projected at a projection position in a real space by a projector. In a first acquisition process, space information regarding a virtual space corresponding to the real space is acquired. In a second acquisition process, display position information regarding a display position corresponding to the projection position in the virtual space is acquired. In a third acquisition process, reference position information regarding a reference position in the virtual space is acquired. In a generation process, an image including an object viewed from the reference position when the object is displayed at the display position in the virtual space is generated as the image content, based on the space information, the reference position information, and the display position information.
