Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

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.

Inventive Principle:
Principle #10Preliminary action

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.
