Engineering Contradiction Analysis
1Measurement precision
If sensor-based solutions are used for monitoring parking spaces, then vehicle detection capability is improved, but installation and maintenance costs increase significantly
Solution Approach 1:
The patent replaces sensor-based detection systems with video-based detection using cameras and image processing algorithms. The system uses video capture devices to monitor parking spaces and computer vision techniques to detect vehicle presence, eliminating the need for physical sensors while maintaining detection accuracy and significantly reducing installation and maintenance costs.
Solution Approach 2:
The system creates visual copies (images and video frames) of the parking area to analyze vehicle presence. By capturing and processing visual information through cameras, the system replicates the detection function of physical sensors using optical copies, thereby reducing hardware costs and complexity.
2Ease of manufacture
If non-stereoscopic video cameras are used for monitoring parking spaces, then system cost is reduced, but license plate recognition accuracy deteriorates for tightly parked vehicles
Solution Approach 1:
The patent transitions from two-dimensional image analysis to three-dimensional spatial reasoning by incorporating depth information and spatial relationships in video frames. The system analyzes the spatial arrangement of vehicles, camera angles, and parking space geometry to compensate for the limitations of non-stereoscopic cameras, enabling accurate license plate recognition without requiring expensive 3D or stereoscopic camera systems.
Solution Approach 2:
The system performs preliminary actions by capturing multiple video frames over time and pre-processing images to enhance license plate visibility. By accumulating temporal information and applying pre-processing techniques such as image enhancement and stabilization, the system improves recognition accuracy for tightly parked vehicles before final analysis.
3Ease of operation
If traditional meters are used for parking management, then payment collection is simplified, but labor costs for inspection and enforcement increase
Solution Approach 1:
The system implements self-service functionality by automatically detecting vehicle presence, calculating parking duration, identifying license plates, and enforcing parking regulations without human intervention. The video-based system continuously monitors parking spaces and autonomously generates enforcement actions, eliminating the need for manual inspection while maintaining simplified payment collection through automated processes.
Solution Approach 2:
The system establishes continuous feedback loops where video data is constantly analyzed, vehicle presence is detected in real-time, and enforcement actions are automatically triggered based on detected violations. This closed-loop feedback mechanism enables automated inspection and enforcement, replacing manual labor while maintaining operational simplicity.
4Measurement precision
If single-space parking meters are deployed, then individual space monitoring is achieved, but space utilization efficiency decreases
Solution Approach 1:
The patent implements a universal video-based monitoring system that can detect and monitor multiple parking spaces simultaneously using a single camera system. The system analyzes video frames to identify vehicle presence across multiple spaces, enabling one camera to perform the function of multiple individual meters while maintaining accurate individual space monitoring and improving overall space utilization efficiency.
