Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If three-dimensional distance-measuring sensor data is integrated with imaging apparatus data having different sampling resolutions, then image quality and consistency are improved, but coordinate conversion accuracy and processing complexity increase
Solution Approach 1:
The patent segments the coordinate conversion process into distinct modules: acquiring positional relationships between sensors, converting three-dimensional coordinates to two-dimensional coordinates, and assigning pixels to screen positions. This modular segmentation reduces processing complexity by making each step independent and manageable while maintaining overall image quality.
Solution Approach 2:
The patent introduces an intermediary coordinate system as a bridge between the three-dimensional distance-measuring sensor data and the two-dimensional imaging apparatus data. This intermediary system facilitates accurate integration by providing a common reference frame, thereby improving image quality without excessively increasing processing complexity.
2Measurement precision
If three-dimensional coordinates are converted into two-dimensional coordinates through interpolation, then image definition is enhanced, but processing time and computational load increase
Solution Approach 1:
The patent performs preliminary coordinate conversion by pre-establishing the positional relationships between sensors and pre-converting three-dimensional coordinates to two-dimensional coordinates before final image rendering. This preliminary action reduces processing time during actual operation while maintaining high image definition through accurate interpolation.
Solution Approach 2:
The patent changes the parameter representation from three-dimensional coordinates to two-dimensional coordinates through interpolation. By transforming the coordinate system parameters and using efficient interpolation algorithms, the patent enhances image definition while controlling computational load and processing time.
