Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If mechanical disposition of cameras is performed during assembly, then camera positioning is established, but mechanical errors cause inconsistency in camera image regions
Solution Approach 1:
The patent performs preliminary calibration by capturing reference images and calculating transformation parameters before actual image composition. This preliminary action compensates for mechanical disposition errors by establishing correction parameters in advance, ensuring image region consistency despite manufacturing imperfections.
Solution Approach 2:
The system changes processing parameters by calculating transformation parameters (rotation, translation, scaling) based on captured reference images. These parameter adjustments compensate for mechanical errors in camera positioning, allowing the system to adapt to actual camera dispositions and ensure consistent image regions in the composite image.
2Reliability
If calibration adjustment is performed after product shipment, then image region consistency can be improved, but user adjustment capability is limited
Solution Approach 1:
The system enables self-service calibration by allowing users to capture reference images and automatically calculate transformation parameters. The calibration process is simplified to basic user actions (capturing reference images) while the complex parameter calculation and adjustment are performed automatically, making post-shipment calibration accessible to end users.
Solution Approach 2:
The system provides feedback by displaying the composite image with adjusted camera regions, allowing users to evaluate the calibration results. This feedback mechanism enables users to iteratively adjust calibration parameters until satisfactory image region consistency is achieved, improving ease of operation while maintaining reliability.
3Reliability
If processing conditions are changed for calibration, then image region consistency is improved, but calibration timing and convenience are reduced
Solution Approach 1:
The system performs calibration as a preliminary step before actual image composition operations. By completing the time-consuming parameter calculation and adjustment process in advance, the system ensures image region consistency is established beforehand, reducing time loss during subsequent imaging operations while maintaining calibration flexibility.

AI summary
An image processing device includes a stitching processing unit that composites composition source images generated from captured images under a preset processing condition to generate a composite image, a screen generation unit that generates a screen and outputs the composite image to a display input device, a touch operation determination unit that determines a camera image region to be adjusted based on a detection result of a touch operation on the screen and determines an adjustment item according to an operation mode of the touch operation, and a processing condition setting unit that sets a temporary processing condition related to the camera image region to be adjusted. The stitching processing unit generates the composition source image from the captured image of the camera corresponding to the camera image region to be adjusted under the temporary processing condition and updates the composite image by compositing the composition source images.
