Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional target object tracking methods are used, then the tracking process can be completed, but the accuracy and success rate of determining trajectory and identification information are low
Solution Approach 1:
The tracking system is divided into multiple independent modules: image acquisition module, target detection module, trajectory calculation module, and identification module. Each module handles a specific aspect of the tracking process, allowing for specialized optimization and improving both accuracy and reliability independently.
Solution Approach 2:
The system performs preliminary target detection and identification before full tracking begins. Reference images are pre-processed and stored in a database, and potential targets are pre-screened using multiple features (appearance, gait, vehicle type) before committing to tracking, which improves success rate by avoiding false starts.
2Measurement precision
If simple tracking methods are used, then the processing speed is fast, but the accuracy of tracking information is insufficient
Solution Approach 1:
The system applies multiple detection methods (appearance-based detection, gait recognition, vehicle type identification) simultaneously, using more detection mechanisms than strictly necessary. This excessive action ensures high accuracy by cross-validating results from multiple sources, while the modular architecture maintains processing efficiency through parallel execution.
Solution Approach 2:
The system replaces traditional mechanical tracking methods with automated image processing and computer vision algorithms. Machine learning models automatically extract features and determine trajectories, substituting manual or simple mechanical tracking with intelligent automated systems that provide both high accuracy and efficient processing.
3Measurement precision
If multiple detection methods are employed to improve accuracy, then the tracking precision increases, but the system complexity increases
Solution Approach 1:
The system employs a universal detection framework that handles multiple target types (pedestrians, vehicles, cyclists) and multiple detection methods (appearance, gait, vehicle type) through a single integrated architecture. This multi-functional design improves identification accuracy across diverse targets while avoiding the complexity of separate specialized systems for each target type.
Solution Approach 2:
The system introduces an intermediary feature extraction and matching layer between image acquisition and target identification. This intermediary module standardizes the output from various detection methods (appearance features, gait features, vehicle features) into a unified format, simplifying the integration of multiple detection methods while maintaining high identification accuracy.
