Parking Area Sensing Cameras Field of View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking area sensing cameras have limited field of view and high hardware and software complexity, making them costly and inefficient for monitoring multiple parking spaces, and drivers cannot determine the location of unoccupied spaces from a single indication light.
Innovation Solution
A pair of parking area sensing cameras is used, where one camera monitors and displays the status of another area, increasing the field of view and reducing hardware complexity by mounting cameras closer to adjacent areas, allowing direct communication and display of parking status without a central server, and using LED lights to indicate availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a single conventional parking area sensing camera is mounted above a driving lane with two lenses to monitor both sides, then the field of view is improved, but the hardware and software complexity increases
Solution Approach 1:
The patent divides the parking area monitoring into separate segments by using individual cameras for each parking area side. Each camera independently monitors one side and displays status on its own housing, eliminating the need for complex multi-lens integration and dual video input processing in a single camera system.
Solution Approach 2:
Each parking area sensing camera is designed to perform multiple functions: monitoring its assigned parking area, processing video input, and displaying status information on its own housing. This universal design allows simple single-lens cameras to achieve the functional equivalence of complex multi-lens systems.
2Ease of manufacture
If a conventional parking area sensing camera is mounted close to the target parking area, then the installation cost is reduced, but the field of view becomes narrow
Solution Approach 1:
The patent segments the parking area into multiple zones, each monitored by a separate camera mounted close to its target area. This segmentation allows each camera to have a narrow but sufficient field of view for its specific zone, while collectively covering the entire parking area with multiple simple, low-cost cameras.
3Ease of manufacture
If a single indication light is used to show parking status, then the hardware cost is reduced, but the driver cannot determine the location of unoccupied spaces
Solution Approach 1:
The patent applies local quality by placing indication lights directly on the housing of each parking area sensing camera at the specific location where parking status is monitored. This allows drivers to see the status indication at the actual parking area location, providing both cost-effectiveness and location information simultaneously.
4Area of moving object
If multiple conventional cameras are used to monitor multiple parking spaces, then the field of view is improved, but the hardware cost and installation complexity increase
Solution Approach 1:
The patent designs each parking area sensing camera as a universal unit that can monitor a specific parking area and display status information independently. This universal design allows the system to achieve wide coverage through multiple simple units rather than requiring expensive complex cameras, reducing overall hardware cost while maintaining comprehensive monitoring capability.
