Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single high-resolution color camera is used, then color image quality is improved, but sensitivity under poor lighting conditions deteriorates
Solution Approach 1:
The imaging system is segmented into two separate camera subsystems: a color camera for capturing color information and a monochrome camera for capturing high-resolution detail. Each sensor is optimized for its specific function, allowing the system to overcome the limitations of a single sensor by dividing the imaging task into specialized components.
Solution Approach 2:
The system merges the outputs of two separate camera systems through image fusion technology. The color image from the color camera and the high-resolution monochrome image from the monochrome camera are combined to produce a final image that possesses both color information and high spatial resolution, thereby achieving both improved image quality and lighting sensitivity.
2Device complexity
If conventional single-camera systems are used, then device complexity is reduced, but ability to determine three-dimensional position deteriorates
Solution Approach 1:
The system transitions from two-dimensional image capture to three-dimensional position determination by utilizing the spatial relationship between two cameras with overlapping fields of view. By comparing the positions of objects in both camera views and applying parallax calculations, the system derives depth information (z-coordinate) to achieve accurate three-dimensional positioning.

Function Achieved in This Case
The system achieves improved sensitivity for color video capture under poor lighting and accurately determines the three-dimensional position of moving objects, enhancing surveillance and monitoring capabilities.
Implementation Method 1
a beam splitter, and a lens, wherein the lens gathers incident light towards the beam splitter, and the beam splitter splits the light towards the two sensor chips
Implementation Method 2
the distance from the cameras to the object in the axis perpendicular to the plane of the images is derived from the parallax error between the two image frames to be fused
