Parking Lot Allocation Strategy for Single Camera Occlusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a plurality of parking spaces in a parking lot are monitored by a single camera, the visibility of certain parking spaces can be obscured by vehicles parked in adjacent spaces, leading to decreased accuracy in monitoring and potential errors in determining the usage status of parking spaces.
Innovation Solution
A parking lot management method and system that allocates available parking spaces based on predetermined entry and exit priorities, ensuring that spaces farther from the camera are prioritized for entry and spaces closer to the camera are prioritized for exit, thereby minimizing the impact of occlusion and maintaining accurate monitoring.

Engineering Contradiction Analysis
1Quantity of substance
If a single camera monitors multiple parking spaces to reduce costs, then the number of cameras is reduced, but the visibility of parking spaces decreases due to occlusion by parked vehicles
Solution Approach 1:
The system pre-establishes an entry priority map that assigns priority levels to different parking spaces based on their spatial relationships and occlusion characteristics. When a vehicle enters the parking lot, the management system refers to this pre-established map to determine which parking space to allocate, proactively preventing occlusion issues before they occur. This preliminary arrangement of parking spaces according to priority ensures that vehicles are directed to spaces that minimize visibility obstruction for the single camera.
2Device complexity
If parking spaces are allocated without considering occlusion, then allocation is simple, but monitoring accuracy decreases due to hidden markers
Solution Approach 1:
The system assigns different entry priorities to different parking spaces based on their local characteristics, specifically their susceptibility to occlusion. Parking spaces that are more likely to be obscured by adjacent vehicles are assigned lower priorities, while spaces with better visibility are assigned higher priorities. This localized differentiation of quality (priority levels) across different parking spaces enables the single camera to maintain accurate monitoring by ensuring that high-priority visible spaces are filled first.
3Ease of operation
If vehicles are parked in spaces closer to the camera first, then allocation is straightforward, but occlusion of farther spaces increases
Solution Approach 1:
Instead of allocating parking spaces in the conventional order (closest to farthest from the camera), the system inverts the allocation strategy by prioritizing farther parking spaces over closer ones. The entry priority map assigns higher priorities to spaces that are farther from the camera and more susceptible to occlusion. This inverted approach ensures that vehicles are directed to distant spaces first, preventing occlusion of these spaces by vehicles that would later park in closer positions.

AI summary
A parking lot includes a plurality of parking spaces monitored by a single camera. A parking lot management method for managing the parking lot includes a parking space allocation process that allocates an available parking space having a highest entry priority among the plurality of parking spaces to an entry vehicle entering the parking lot. The plurality of parking spaces include a first parking space and a second parking space that is closer to an installation position of the single camera than the first parking space is. An entry priority of the first parking space is higher than an entry priority of the second parking space.
