Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single camera stand is used to generate compensation coefficient value at the nearest observation point, then the color cast problem is avoided at that specific observation point, but the compensation is greatly limited when the observation point changes
Solution Approach 1:
The patent divides the compensation system into multiple control devices, each responsible for specific spatial regions. Multiple camera stands are deployed at different positions, and each generates compensation coefficient values for its designated observation points. This segmentation allows the system to maintain high compensation accuracy across multiple locations simultaneously, resolving the contradiction between precision at a single point and adaptability to multiple points.
Solution Approach 2:
The patent introduces a spatial dimension by establishing a spatial model that maps multiple observation points in three-dimensional space. Instead of treating compensation as a single-point operation, the system creates a spatial distribution of compensation coefficient values across multiple observation points. This dimensional expansion enables the system to provide accurate compensation at multiple locations without sacrificing precision at any individual point.
2Reliability
If the image acquisition device is fixed at a specific observation point to photograph the image without color cast, then the color cast problem is avoided, but the flexibility in image capture is restricted
Solution Approach 1:
The patent transforms the static, fixed-position compensation approach into a dynamic system where multiple camera stands can operate from different positions. The system dynamically assigns observation points to different control devices based on spatial coordinates, allowing the image acquisition device to move between predefined observation points while maintaining compensation accuracy. This dynamic allocation preserves image quality consistency while enabling flexible repositioning.
Solution Approach 2:
The patent creates a universal compensation framework where multiple control devices share a common spatial model and compensation algorithm. Each control device can serve multiple functions: generating compensation coefficients for its assigned regions, receiving images from various sources, and applying compensation based on spatial position. This multi-functionality allows the image acquisition device to operate flexibly from different positions while maintaining reliable image quality through the universal compensation mechanism.
