3D Augmentation via Vanishing Point Geometric Scaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Binocular disparity weakens the 3D effects of 2D images, as the strongest 3D information, it overrides other 3D cues, making it difficult to enhance 3D effects in traditional 2D image displays.
Innovation Solution
The method involves setting a vanishing point or vertical vanishing line on the image and augmenting the geometric perspective based on this point or line, which adjusts the horizontal widths of objects relative to their distance from the vanishing point or line, thereby enhancing the 3D effect.

Engineering Contradiction Analysis
1Manufacturing precision
If binocular disparity is used to achieve 3D effects, then the strongest 3D information is obtained, but other 3D information in 2D images is weakened
Solution Approach 1:
The patent segments the image processing into multiple zones based on distance from the vanishing point, with each zone applying different geometric transformation parameters. This allows selective enhancement of 3D effects in different regions without uniformly affecting the entire image, thereby preserving other 3D information while augmenting geometric perspective.
Solution Approach 2:
The patent applies local quality by using different processing parameters for different regions of the image. Specifically, pixels closer to the vanishing point undergo different geometric transformations compared to pixels farther away, creating localized 3D enhancement that adapts to the spatial structure of the scene.
2Manufacturing precision
If traditional image processing methods are used to augment 3D information, then 3D effects can be enhanced, but the processing becomes complicated and time-consuming
Solution Approach 1:
The patent extracts the essential element for 3D enhancement - the vanishing point or vertical vanishing line - and uses it as the core reference for all subsequent processing. By focusing on this single extracted feature rather than complex multi-parameter optimization, the method achieves 3D augmentation with simplified processing suitable for real-time applications.
Solution Approach 2:
The patent changes geometric parameters (horizontal width scaling) based on the distance from the vanishing point. By systematically varying this single parameter across different zones rather than adjusting multiple image properties simultaneously, the method achieves effective 3D augmentation while maintaining processing efficiency.
3Manufacturing precision
If multiple vanishing points are used in geometric perspective, then more accurate 3D representation is achieved, but image processing becomes more difficult
Solution Approach 1:
The patent applies partial action by using only one vanishing point or vertical vanishing line for processing, which is sufficient to achieve the desired 3D effect for most practical applications. This selective approach avoids the complexity of multiple vanishing points while still providing effective geometric perspective enhancement.
