Automated Entrance Permit Validation via Computer Vision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional entrance permit control methods are time-consuming and labor-intensive, especially in large venues, and often require manual validation, which can slow down the entry process and divert attention from security and other welcoming aspects.
Innovation Solution
A system that uses computer vision to remotely monitor an entrance region, detect, and track entrance permits carried by individuals, allowing for automated validation without the need for mechanical gates, by projecting visual feedback indicating validation success or failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual inspection or scanning of entrance permits is used, then validation accuracy is maintained, but entrance processing speed decreases and labor intensity increases
Solution Approach 1:
The patent replaces manual mechanical inspection and scanning processes with an automated optical system using imaging devices and computer vision algorithms. The system captures images of entrance permits, automatically detects and validates codes through image processing, and provides automated feedback, eliminating the need for manual scanning while maintaining validation accuracy and significantly improving processing speed.
2Ease of operation
If manual validation is performed, then security monitoring is possible, but entrance hosts are diverted from security and welcoming tasks
Solution Approach 1:
The system enables self-service validation where the entrance permit itself serves as the validation target. The automated imaging and recognition system processes permits without requiring entrance host intervention, allowing hosts to focus entirely on security monitoring and welcoming tasks while the system handles validation autonomously.
3Productivity
If mechanical gates with scanning stations are used, then automated validation is achieved, but entry process becomes rigid and slower
Solution Approach 1:
The patent extracts the validation function from the mechanical gate infrastructure. Instead of requiring permits to be validated at fixed scanning stations integrated into gates, the system uses portable imaging devices that can validate permits anywhere in the entrance region, removing the constraint of fixed mechanical infrastructure and enabling more flexible, faster processing.
4Ease of operation
If traditional scanning stations are required, then validation accuracy is ensured, but entrance region becomes crowded and less seamless
Solution Approach 1:
The patent transitions from a linear, station-based validation approach to a spatially distributed validation system. Multiple imaging devices positioned at different locations and angles capture images of permits throughout the entrance region, allowing validation to occur in three-dimensional space rather than at fixed one-dimensional scanning points, thereby reducing crowding and improving seamlessness.

AI summary
A system for entrance permit control is configured to monitor individuals (1) in an entrance region (100) that includes an entrance (110) to a restricted area. The system performs a monitoring method to enable a seamless entrance experience for the individuals (1). The system receives a stream of digital images of the entrance region (100), and processes the received stream of digital images for detection of a machine-readable code, MRC, displayable on an entrance permit (10) carried by an individual (1) in the entrance region (100). The system further tracks, based on the received stream of digital images, a location of the MRC (12) within the entrance region (100), initiates a validation of the MRC (12), and provides, in dependence of the validation and position data generated by the tracking, a visual indication (14) of a result of the validation on at least one of the entrance permit (10) and the individual (1).
