Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a camera is positioned far from the object to track, then the coverage area increases, but the tracking accuracy becomes degraded
Solution Approach 1:
The patent combines detection results from multiple cameras positioned at different locations into a unified tracking result. By integrating information from multiple sensors, the system achieves both wide coverage and high tracking accuracy, resolving the contradiction between coverage area and tracking accuracy.
2Measurement precision
If multiple cameras are used to improve tracking accuracy, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The tracking device integrates multiple functions including detection, coordinate transformation, and result integration within a single system. This multi-functional approach allows the system to handle multiple cameras and perform complex operations while maintaining manageable complexity through unified processing.
Solution Approach 2:
The patent introduces a common coordinate system as an intermediary to unify detection results from multiple cameras with different coordinate systems. This mediator enables accurate integration of tracking information while simplifying the complexity of coordinating multiple sensors.
3Measurement precision
If detection results from multiple sensors are integrated, then the tracking accuracy improves, but the processing complexity increases
Solution Approach 1:
The system performs coordinate transformation of detection results into a common coordinate system before integration. This preliminary action standardizes the data from multiple sensors, making the subsequent integration process more straightforward and reducing processing complexity while maintaining high tracking accuracy.
