Multi-Projector 3D Display with Variable Angular Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D display technologies face a tradeoff between spatial resolution and angular resolution due to limitations in pixel density, which affects the perception of 3D depth.
Innovation Solution
The method involves using a first projector to project a high-resolution image within a small region of the screen, achieving a high angular resolution, while a second projector projects lower-resolution secondary content on the remaining screen area, reducing bandwidth and processing requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single projector projects high-resolution content across the entire screen, then angular resolution is improved, but bandwidth and processing requirements increase significantly
Solution Approach 1:
The display screen is divided into multiple regions, with a first region receiving high-resolution projected content and a second region receiving lower-resolution content. This segmentation allows the system to provide high angular resolution where needed while reducing overall bandwidth requirements by applying lower resolution to peripheral regions.
2Measurement precision
If a single projector projects high-resolution content across the entire screen, then angular resolution is improved, but device complexity increases
Solution Approach 1:
The system segments the projection task across multiple projectors, where a first projector handles a specific first region with high resolution and a second projector handles the remaining region with lower resolution. This division of labor reduces the complexity burden on any single projector while maintaining overall high angular resolution in the primary viewing area.
3Measurement precision
If pixel density is increased to improve 3D depth perception, then angular resolution is improved, but manufacturing precision requirements increase
Solution Approach 1:
The system applies different quality levels to different regions of the display. The first region, which corresponds to the primary viewing area, receives high-resolution content with high pixel density for superior angular resolution and 3D depth perception. The second region receives lower-resolution content, reducing the overall manufacturing precision requirements while maintaining excellent quality where it matters most.

AI summary
A method includes projecting, by a first projector, a first image to a first region, the first image having a first angular resolution and a first number of views. The method also includes projecting, by a second projector, a second image to a second region, the second image having a second angular resolution and a second number of views, where the second region is within the first region, the second angular resolution is greater than the first angular resolution, and the second number of views is greater than the first number of views.
