Multi-person Continuous Fever Screening
@ $300

A thermal vision-based low-cost system for continuous detection of fever in large populations to combat the spread of infectious diseases such as COVID-19


One of the key challenges in containing infectious diseases such as COVID-19 from spreading is the lack of a safe and cost-effective way to perform early detection of potential carriers at scale. It is particularly damaging when the virus has a long incubation period, rendering 1-shot checks, such as those performed at airports, largely ineffective. What is desperately needed is an inexpensive way to continuously screen large populations, such as in hospitals, workspaces, classrooms, buses, cafes, and homes. This project aims to use low-cost (~$300) thermal cameras to perform continuous skin temperature measurements, enabling anyone to perform fever screening remotely and safely.

System Design

Thermal Sensing

Our system uses inexpensive thermal cameras (~$300) that anyone can install and use.

People Detection

We automatically detect people to enable placement in different environments.

Robust Models

We develop accurate 3D thermal models to ensure correct identification of people with fever.

Real-Time Mobile Alerts

The system generates real-time notifications to alert users.

System Details

Our system is composed of six main subcomponents. The different subcomponents connect to extract features from the RGB and thermal images, and output fever predictions for any occupants in view. Thermal and RGB image features are fused into 3D point-cloud models of heads to improve accuracy.
