Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single color filter array pattern is used, then the device complexity is low, but the detection precision for different types of objects is suboptimal
Solution Approach 1:
The color filter array is divided into multiple distinct patterns (first pattern, second pattern, third pattern), each optimized for detecting specific types of objects. This segmentation allows each pattern to specialize in detecting particular features while collectively covering a broader range of detection needs, thereby improving overall detection precision without requiring a complete redesign of the entire filter array.
Solution Approach 2:
Different regions of the color filter array are assigned different patterns based on the specific detection requirements for those regions. For example, certain patterns are optimized for traffic lights while others are optimized for lane markers. This local quality approach ensures that each region of the array has the optimal filter configuration for its specific detection task, improving detection precision for diverse objects.
2Measurement precision
If multiple color filter patterns are used, then the detection precision for different objects is improved, but the manufacturing complexity increases
Solution Approach 1:
The color filter array apparatus is designed to perform multiple detection functions using a single integrated structure. The first, second, and third patterns work together to detect various objects including traffic lights, lane markers, and other features. This multi-functionality allows the system to achieve high detection precision for diverse objects while maintaining a unified manufacturing process, reducing the need for separate filter arrays for each detection task.
3Measurement precision
If color filters are arranged in different patterns, then the detection capability for specific objects is optimized, but the image viewing quality for human display may be compromised
Solution Approach 1:
The first pattern, second pattern, and third pattern are merged into a single color filter array apparatus, where each pattern contributes its specialized detection capability. The third pattern is specifically designed to optimize image viewing quality for human display, while the first and second patterns optimize detection for specific objects. By combining these patterns, the system achieves both specialized detection capability and overall image viewing quality simultaneously.
