Fusing mmWave and RGBD Sensor for Vitalsign Detection in Sleep and Respiratory Applications

This paper proposes a dual-sensor fusion system that combines a Frequency Modulated Continuous Wave (FMCW) radar and an Intel RealSense RGB+Depth (RGBD) sensor as non-contact physiological signal sensing devices. Through the fusion of point clouds obtained from the dual-sensor system, the spatial information and vital sign signals can be perceived.
