A camera-based multispectral setup for remote vital signs assessment

Abstract

Photoplethysmography Imaging and Infrared thermography are the two imaging modalities studied at the Philips Chair for Medical Information Technology which allow for remote assessment of vital signs such as heart rate, heart rate variability, breathing rate, oxygen saturation and temperature distribution. Both modalities use video cameras for recording different parts of the electromagnetic spectrum and deliver 2D images or videos. In this work, we will introduce the Philips-MedIT camera setup for multispectral measurements and set it into context with earlier developments at RWTH Aachen University.
