Wide-area fever screening using advanced digital imaging

摘要

Wide-area temperature monitoring and feverscreening to mitigate COVID-19 using a long-wave infrared digital pixel focal plane array camera scanning systemand real-time temperature estimation processing is presented. The system enables multi-pose temperature readings of more than 20 people simultaneously overa 90° horizontal x 30° vertical field-of-regard at a 1 Hz update rate and+/- 0.6℉ accuracy. The systemhas been operational in the MIT LL lobby since April 2020.
