Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional perspective correction methods are used, then the processing speed is relatively fast, but the perspective correction effect is not good enough to satisfy user demands
Solution Approach 1:
The patent segments the perspective correction process into multiple processing stages: obtaining perspective correction direction, determining transformation information, and performing correction processing. This segmentation allows for more precise control at each stage while maintaining overall processing efficiency.
Solution Approach 2:
The patent introduces a new dimension of processing by utilizing both preset directions (horizontal/vertical) and custom directions for perspective correction. This multi-dimensional approach enables more accurate perspective transformation while optimizing processing speed through directional-specific algorithms.
2Adaptability or versatility
If generic perspective correction is applied, then the processing is simple and fast, but it cannot satisfy diverse user optimization demands
Solution Approach 1:
The patent implements dynamic processing by allowing users to select between preset directions and custom directions based on their specific needs. The system adapts its processing approach according to the selected direction type, providing versatility without requiring complex processing for all cases.
Solution Approach 2:
The patent applies local quality by using different processing strategies for different directions. Preset directions (horizontal/vertical) use optimized algorithms, while custom directions use adaptive algorithms. This allows the system to be complex only where necessary and simple where sufficient.
3Measurement precision
If perspective correction is performed without considering specific directions, then the processing is straightforward, but the correction accuracy for different viewing angles is insufficient
Solution Approach 1:
The patent changes key parameters (processing approach) based on the perspective correction direction. For preset directions, it uses fixed transformation parameters, while for custom directions, it calculates adaptive parameters. This parameter adaptation improves accuracy without significantly complicating the user operation.
