Engineering Contradiction Analysis
1Measurement precision
If thermal sensor data and machine learned models are used to analyze heat signatures, then measurement precision of object behavior prediction is improved, but device complexity increases
Solution Approach 1:
The system segments thermal data into distinct heat signatures corresponding to different object features (e.g., engine, wheels, exhaust pipe for vehicles; body, limbs for pedestrians). This segmentation allows the machine learned model to analyze specific thermal patterns independently, improving prediction accuracy while managing computational complexity through focused analysis of discrete thermal regions.
Solution Approach 2:
The patent introduces thermal analysis component as an intermediary layer between raw thermal sensor data and the autonomous vehicle's decision-making system. This intermediary processes thermal data, extracts heat signatures, and provides processed information to higher-level systems, thereby improving measurement precision while shielding the core control system from thermal data complexity.
2Reliability
If thermal data analysis is implemented to determine object states, then reliability of behavior prediction is improved, but difficulty of detecting and measuring increases
Solution Approach 1:
The system utilizes thermal signatures as visual indicators of object states, where different temperature patterns and heat distributions serve as detectable markers for various conditions (e.g., active vs. inactive vehicle states). This approach transforms invisible thermal energy into measurable and interpretable data, improving reliability of predictions while making thermal detection more straightforward through established thermal imaging technology.
Solution Approach 2:
The patent monitors changes in thermal parameters over time to determine object states and predict behavior. By tracking temperature variations, heat signature patterns, and thermal distribution changes, the system achieves reliable behavior prediction without requiring complex detection methods, as thermal parameters naturally change with object state transitions.
