Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a camera is positioned far from the object to cover a wider area, then the coverage area increases, but the tracking accuracy degrades
Solution Approach 1:
The patent combines detection results from multiple sensors (cameras) to generate tracking information. By merging data from multiple viewing angles and distances, the system achieves both wide coverage and high tracking accuracy, resolving the contradiction between coverage area and tracking precision
Solution Approach 2:
The patent introduces a coordinate system conversion and integration mechanism as an intermediary process. This mediator transforms detection results from different sensor coordinate systems into a unified coordinate system, enabling accurate object tracking across multiple cameras regardless of their positions
2Measurement precision
If multiple sensors are used to improve tracking accuracy, then the tracking precision improves, but the system complexity increases
Solution Approach 1:
The patent creates a universal coordinate system integration framework that can handle detection results from multiple different sensor types and positions. This multi-functional approach allows the same processing methodology to be applied regardless of the number or type of sensors, managing complexity while maintaining improved tracking accuracy
