Engineering Contradiction Analysis
1Reliability
If deep learning-based object detection algorithms are used, then object detection capability is improved, but performance decreases under suboptimal lighting conditions
Solution Approach 1:
The system performs preliminary actions by capturing reference images of the object under controlled lighting conditions before actual detection occurs. These reference images are used to generate training data that teaches the deep learning algorithm what the object looks like under optimal lighting, enabling better detection performance even when lighting conditions are suboptimal during actual use.
Solution Approach 2:
The system implements feedback mechanisms where the deep learning algorithm continuously refines its object detection capabilities based on reference images and training data. The algorithm learns from the relationship between reference images and actual detection scenarios, adjusting its internal models to compensate for varying lighting conditions and improve overall detection reliability.
2Reliability
If lighting conditions are optimized for object detection, then detection performance is improved, but system complexity increases
Solution Approach 1:
The system performs self-service by automatically capturing reference images, generating training data, and training the deep learning algorithm without requiring manual intervention or complex external control systems. The system self-adjusts and self-optimizes its detection performance based on the reference images and training data it generates itself.
Solution Approach 2:
The system changes parameters by adjusting the training data generation process, reference image capture parameters, and algorithm training parameters to optimize detection performance. By systematically varying and optimizing these parameters, the system achieves better detection accuracy without requiring complex hardware modifications or system reconfigurations.
