Patent attributes
Devices and methods are provided for performing remote physiological monitoring of vital signs from one or more subjects. Camera pairs including an intensity camera and a depth camera are used to obtain intensity image data and depth image data that are then processed using one or more ROIs for extracting heart rate and respiratory waveforms from which the heart rate and respiratory rate may be estimated. In other embodiments, multiple ROIs may be used to obtain several heart rate and respiratory rate values which are then fused together. In some embodiments motion compensation may be used prior to generating the heart rate and respiratory waveforms. In other embodiments, multiple camera pairs may be used to obtain intensity and depth data from multiple fields of view which may be used to obtain several heart rate and respiratory rate values which are then fused together.
