Solution Overview
Problem
Traditional head-mounted display devices have a narrow 3D image display angle and fuzzy edge processing, which limits the user's immersive experience.
Innovation Solution
A 3D image display method that involves building a 3D background model, projecting video image data into it, performing image morphing and smoothing processing, and displaying the images through two lenses to generate wide-angle 3D video images for each eye, enhancing the visual angle and clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional head-mounted devices perform fuzzy processing on the edge portion of each frame, then the edge portion becomes fussy and the 3D image display angle becomes narrow, but this processing method is simple and easy to implement
Solution Approach 1:
The patent introduces a 3D background model dimension to transform the traditional 2D frame processing approach. By projecting video image data into a 3D background model and performing image morphing processing, the system achieves wide-angle 3D image display without compromising implementation simplicity.
Solution Approach 2:
The patent performs preliminary actions by building a 3D background model and pre-processing the video image data before display. The image morphing processing is performed in advance to generate the first and second 3D video images, which then can be displayed with wide angle without requiring complex real-time processing.
2Device complexity
If traditional head-mounted devices focus on displaying movie content, then the device structure remains simple, but users do not feel like watching movies in a theater
Solution Approach 1:
The patent nests the video image display area within the 3D background model, creating an immersive theater-like environment. The first and second 3D video images are displayed within the 3D background model through two lenses, achieving both simplicity and immersive experience.
Solution Approach 2:
The patent creates a virtual copy of the theater experience by projecting video image data into a 3D background model. This virtual theater environment replicates the immersive feeling of watching movies in a theater while maintaining relatively simple device structure.
3Adaptability or versatility
If image morphing processing is performed on the 3D background model, then the visual angle becomes wide and clarity improves, but the processing complexity increases
Solution Approach 1:
The patent performs image morphing processing as a preliminary action to generate the first and second 3D video images before display. By pre-computing the morphed images based on the 3D background model and video image data, the system achieves wide visual angle without requiring complex real-time processing during display.
