A Millimeter-Wave Radar and Kinect(TM) Depth Camera for Non-Contact Respiratory Sensing.

摘要

Remote, non-contact respiratory sensing has gained interest in the past decade with the dawn of cheaper microwave integrated circuits and optical devices. The need for an inexpensive and portable respiratory monitor is in particular demand in a hospital setting as the respiratory rate provides early warning for cardiorespiratory arrest. This thesis explores the hypothesis that an inexpensive millimeter-wave (MMW) radar module can synergize with an infrared (IR) camera to provide a low-cost module for accurate, long-term measurement of respiratory rate.;Both the IR camera system and the MMW radar technique are experimentally validated. Promising results are presented for the IR camera in which the respiratory rate is accurately measured for different scenarios. Measurements with the MMW radar indicate that more expensive and complex hardware are required to achieve adequate results.
