Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate brackets are used to connect color camera and IR camera, then alignment precision is improved, but device complexity and design flexibility deteriorate
Solution Approach 1:
The patent merges the alignment function into the processor through software algorithms. The processor receives images from both cameras and performs computational alignment by comparing feature points and calculating transformation matrices, eliminating the need for separate physical brackets while achieving precise alignment through digital image processing.
Solution Approach 2:
The patent replaces the mechanical bracket system with a computational system. Instead of using physical structures to maintain camera alignment, the system uses image processing algorithms that analyze feature points, calculate spatial transformations, and digitally align images from cameras with different positions and orientations.

3Manufacturing precision
If color pattern images are processed to generate high dynamic range color images, then image quality is improved, but processing time increases
Solution Approach 1:
The patent performs preliminary actions by generating transmission maps and luminance contrast maps from the color pattern images before final HDR image synthesis. These intermediate maps are created by analyzing specific pixel characteristics and are stored for use in the subsequent HDR generation process, enabling efficient processing by preparing data in advance.
Solution Approach 2:
The patent segments the HDR image generation process into distinct stages: generating transmission maps from color pattern images, creating luminance contrast maps, and finally synthesizing the HDR color image. This segmentation allows each processing stage to be optimized independently and enables parallel processing of different image regions or channels.
