Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital image editing systems fail to accurately and efficiently align objects across different perspectives, leading to inflexible, inaccurate, and inefficient results due to reliance on perspective-based grids and manual user input.
Innovation Solution
The cross-perspective alignment system extracts snappable line segments from objects and generates alignment bin maps to determine a modified alignment, allowing objects to be positioned flexibly and accurately across perspectives without grid constraints, using automated object positioning based on the alignment of objects in other perspectives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If perspective-based grids and manual user input are used for aligning objects, then the system is easy to operate, but the alignment accuracy and flexibility deteriorate
Solution Approach 1:
The system automatically determines alignment relationships between objects across different perspectives without requiring manual user input. The automated alignment algorithm analyzes the spatial relationships and perspective transformations to compute accurate alignment positions, allowing the system to serve itself rather than relying on user expertise for precise alignment.
Solution Approach 2:
The patent replaces manual mechanical adjustment with automated computational algorithms. Instead of requiring users to manually position objects based on visual estimation, the system uses image processing techniques, perspective transformation models, and automated optimization to calculate precise alignment positions, substituting human operation with computational mechanisms.
2Device complexity
If perspective-based grids are used for alignment, then the system structure is simple, but the adaptability to different perspectives deteriorates
Solution Approach 1:
The system dynamically adjusts alignment parameters based on the detected perspective type and spatial relationships between objects. Instead of using a fixed grid structure, the algorithm computes perspective-specific transformation parameters including vanishing point locations, horizon line positions, and depth cues, allowing the same system to adapt to various perspective configurations without changing its fundamental structure.
Solution Approach 2:
The patent creates a universal alignment system that can handle multiple perspective types (one-point, two-point, three-point perspective, oblique, and no-perspective views) through a single integrated algorithm. The system identifies the perspective type automatically and applies appropriate transformation models, making it multi-functional across different visual scenarios without requiring separate specialized systems for each perspective type.
3Manufacturing precision
If automated alignment algorithms are implemented, then the alignment accuracy improves, but the computing resources required increase
Solution Approach 1:
The system performs preliminary analysis of the digital image to detect objects, their positions, and perspective characteristics before executing the full alignment computation. By pre-processing the image to identify key features, estimate perspective transformations, and prepare alignment candidates, the system reduces the computational burden of the main alignment algorithm while maintaining high accuracy through targeted processing rather than brute-force computation.
