Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current single-person kiosk-style body temperature scanning solutions are disruptive and slow, creating choke points that disrupt business flow and require patrons to wait in line, while multi-lane setups are desired to allow continuous patron flow without stopping.
Innovation Solution
A multi-lane elevated body temperature scanning system using GigE vision and tracking, employing machine learning and multiple thermal cameras to track and scan multiple individuals simultaneously, eliminating the need for individual pauses and enhancing throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single thermal camera is used for temperature scanning, then the equipment cost is reduced, but the scanning throughput and productivity are limited to one person at a time
Solution Approach 1:
The system divides the scanning area into multiple virtual lanes within a single camera field of view. Each lane is independently tracked and scanned, allowing simultaneous processing of multiple individuals without requiring multiple physical cameras or complex multi-camera synchronization systems.
Solution Approach 2:
The patent transitions from sequential one-dimensional scanning (one person at a time) to parallel multi-lane scanning by utilizing the two-dimensional field of view of a single thermal camera. Multiple scanning lanes are created across the horizontal dimension, enabling simultaneous scanning of multiple individuals across different lanes.
2Productivity
If traditional kiosk-style scanning is used, then temperature screening accuracy is maintained, but patron flow is disrupted and wait time increases
Solution Approach 1:
The system performs preliminary temperature screening as patrons naturally walk through the scanning area without requiring them to stop or queue. The tracking algorithm continuously monitors temperature data during movement, completing the screening action before patrons would need to pause, thereby eliminating wait time while maintaining screening accuracy.
Solution Approach 2:
The scanning process is made continuous by tracking patrons throughout their movement across the scanning area rather than requiring discrete stop-and-scan moments. The system maintains continuous temperature monitoring and tracking as individuals walk through multiple virtual lanes, eliminating interruptions and maintaining steady patron flow.
3Productivity
If multiple thermal cameras are deployed for multi-lane scanning, then scanning throughput increases, but system complexity and cost increase
Solution Approach 1:
A single thermal camera is made multi-functional by implementing software-based virtual lane division and tracking capabilities. The same camera hardware performs the work of multiple cameras by creating and managing multiple independent scanning lanes within its field of view, eliminating the need for additional camera equipment while achieving multi-lane throughput.

AI summary
A multi-lane elevated body temperature preventative scanning solution using GigE vision and tracking. This multi-lane solution is used to scan and track movement of people through an elevated body temperature scanning solution. When a person enters the frame, their identity (ID) is tracked within the field of view of the thermal camera in a designated scanning area from there it is monitored through the entry and exit of a premise to acquire a preventative temperature screening. Multiple machine learning and tracking routines are used together in this innovative offering.
