Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a lidar module is used to perform three-dimensional imaging, then the imaging precision and completeness are improved, but the hardware cost and device complexity increase significantly
Solution Approach 1:
The patent uses ordinary cameras to capture two-dimensional images and processes them through coordinate transformation algorithms to generate three-dimensional imaging results, effectively copying the function of expensive lidar modules using readily available camera hardware combined with computational methods
Solution Approach 2:
The patent replaces the mechanical/optical ranging system (lidar) with a computational imaging system that uses standard cameras and coordinate transformation algorithms to achieve three-dimensional reconstruction, substituting physical measurement mechanisms with mathematical processing
2Ease of operation
If the photographing position is not fixed during three-dimensional imaging, then the adaptability and ease of operation are improved, but cumulative errors increase leading to reduced measurement precision
Solution Approach 1:
The patent introduces a coordinate transformation mechanism that operates in the mathematical dimension, transforming images from different spatial positions into a unified three-dimensional coordinate system, thereby eliminating cumulative errors while preserving photographing flexibility
Solution Approach 2:
The patent uses a standard three-dimensional coordinate system as an intermediary framework to integrate multiple two-dimensional images taken from different positions, allowing flexible photographing while maintaining measurement precision through systematic coordinate alignment
