Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-camera multi-target tracking algorithms are implemented with sophisticated processing, then tracking quality and detection accuracy are improved, but hardware resource demand and computing costs increase significantly
Solution Approach 1:
The system dynamically adjusts configuration parameters of tracking devices based on real-time performance metrics and resource availability. The configurators modify processing capabilities, resolution, and frame rates adaptively to optimize the balance between tracking quality and hardware resource consumption.
Solution Approach 2:
The system changes physical and operational parameters of tracking devices including processing capability, image resolution, and frame rate. These parameter adjustments allow the system to maintain acceptable tracking quality while reducing computational load and hardware resource demand when resources are constrained.
2Area of stationary object
If a large number of cameras are deployed for comprehensive surveillance coverage, then monitoring area and detection capability are improved, but computing costs and hardware resource requirements become prohibitive
Solution Approach 1:
The surveillance system is divided into multiple independent tracking devices, each responsible for specific camera feeds and target tracking tasks. This segmentation allows distributed processing where each device handles a portion of the total computational load, making large-scale deployments feasible without requiring centralized supercomputing resources.
Solution Approach 2:
The system applies partial processing by selectively adjusting the processing capability of individual tracking devices based on local conditions and resource availability. Not all cameras require maximum processing power simultaneously, allowing the system to maintain comprehensive coverage while reducing overall computing costs through selective optimization.
3Reliability
If tracking priority is given to particular targets by allocating more resources, then detection accuracy for priority targets is improved, but tracking quality of other targets is temporarily reduced
Solution Approach 1:
The system applies different processing qualities and resource allocations to different tracking devices and targets based on local requirements. Priority targets receive enhanced processing resources from specific tracking devices, while other devices maintain standard operation, allowing differentiated quality of service without uniformly reducing overall system capability.
Solution Approach 2:
The system dynamically changes configuration parameters of tracking devices to prioritize specific targets when needed. By adjusting processing capability, resolution, and frame rate parameters selectively, the system can allocate more resources to priority targets while maintaining acceptable performance for other targets, preserving overall tracking flexibility.
4Productivity
If configuration parameters are continuously adjusted to reduce hardware resource demand, then resource efficiency is improved, but system complexity and control difficulty increase
Solution Approach 1:
The system uses performance metrics as feedback to automatically adjust configuration parameters. Tracking devices monitor their own performance and resource consumption, and configurators use this feedback to make automatic parameter adjustments. This closed-loop control reduces system complexity by automating the optimization process rather than requiring manual intervention.
Solution Approach 2:
Tracking devices and configurators are designed to self-adjust their configuration parameters based on performance metrics and resource conditions. The system serves itself by automatically optimizing resource allocation and processing capabilities without requiring external control, reducing operational complexity while maintaining high resource efficiency.
