VR Image Rendering with 3D Object Models for Distant Object Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies struggle to represent objects far from the base point in high resolution, leading to difficulty in visually recognizing these objects accurately in generated direction images.
Innovation Solution
An image processing apparatus that generates a VR image by obtaining object models from multiple viewpoints, determining virtual object positions, and setting a base point to create a VR image with enhanced representation of distant objects using virtual objects disposed near the base point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a direction image is generated by clipping a partial image region from a panoramic image or omnidirectional image, then the base point can be set at a specific position, but objects far from the base point are reduced in resolution and become difficult to visually recognize
Solution Approach 1:
The patent transitions from 2D panoramic image clipping to 3D virtual space rendering. By constructing a three-dimensional space from multi-viewpoint images and rendering direction images from virtual viewpoints in this 3D space, the system maintains high resolution for distant objects while enabling flexible directional viewing, thus resolving the resolution loss problem inherent in 2D clipping methods
Solution Approach 2:
The patent creates virtual copies of the imaging region in three-dimensional space. By generating virtual viewpoint images that replicate the spatial relationships and visual information from multiple captured images, the system preserves high-resolution representations of distant objects without requiring physical proximity to the base point
2Adaptability or versatility
If multi-viewpoint images are used to generate virtual viewpoint images for combining into a panoramic image, then a base point can be established, but the representation of distant objects remains low in resolution
Solution Approach 1:
The patent elevates the processing from 2D image manipulation to 3D spatial rendering. By constructing a three-dimensional space from multi-viewpoint images and performing rendering operations in this volumetric space, the system maintains high resolution for objects at all distances while preserving the flexibility to position base points anywhere in the virtual environment
Solution Approach 2:
The patent applies different processing qualities to different regions of the virtual space. By rendering direction images from virtual viewpoints that are strategically positioned, the system ensures high-resolution representation for objects in all directions from the base point, including distant objects that would otherwise be low-resolution in clipped panoramic approaches
