UAV-Based IoT System for Public Temperature Surveillance Using Thermal Imaging

Abstract

Elevated body temperature is often an early indicator of potential COVID-19 infection, making its timely detection crucial for controlling the spread of the virus. Resent research underscores the versatility and advantages of unmanned aerial vehicles (UAVs) in various civilian applications. Building on these strengths, this study presents the design and implementation of a UAV-based temperature monitoring system for public areas to be used by the authorities. The design and development of this UAV based system, equipped with a thermal imaging sensor, autonomously patrols a defined area to continuously monitor individuals’ body temperatures. When a person with temperature above the normal threshold is detected, the UAV captures an image of the individual and stores it locally, while simultaneously sending an alert to a central control unit to initiate appropriate action. The system's successful development demonstrates the practicality and effectiveness of the proposed solution for real-time public health surveillance.
