Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intrinsic parameters are checked for each camera model change, then correct parameters are used for applications, but application software complexity and run times increase
Solution Approach 1:
The patent creates a unified camera model that can serve multiple camera models universally. Instead of maintaining separate intrinsic parameter sets for each camera model, a single unified model with unified parameters is developed that can accurately represent multiple different camera models, thereby reducing software complexity while maintaining reliability
Solution Approach 2:
The patent transforms the approach from using multiple model-specific parameter sets to using a single set of unified parameters. By changing the parameter representation from model-specific to model-agnostic, the system eliminates the need for complex model identification and parameter selection logic in the application software
2Reliability
If intrinsic parameters are checked for each camera model change, then correct parameters are used for applications, but run times increase
Solution Approach 1:
The unified camera model and its parameters are pre-computed and established during a calibration phase, before actual application execution. This preliminary action eliminates the need for time-consuming parameter checks during runtime, as the unified parameters are already optimized and ready for immediate use across all supported camera models
Solution Approach 2:
The unified camera model serves all camera models simultaneously, eliminating the need for runtime model identification and parameter selection. Applications can directly use the unified parameters without checking which specific camera model is in use, thereby reducing execution time while maintaining parameter accuracy
3Adaptability or versatility
If multiple camera models are supported with model-specific parameters, then each camera model can be used, but the system requires complex model identification and parameter selection
Solution Approach 1:
The patent develops a unified camera model that can universally represent multiple different camera models. This unified model eliminates the need for complex model identification and parameter selection logic, as the same unified parameters can be applied across all supported camera models while maintaining adaptability through the unification transformation process

AI summary
A vehicle includes a system performing a method of operating a camera for the vehicle. The camera is configured to capture an image. The processor is configured to query the camera to obtain an intrinsic parameter of the camera, estimate a unified parameter based on the intrinsic parameter of the camera, and perform at least one application on the image using the unified parameter.
